When flexing, the \"top\" truss resists tension and the \"bottom\" truss resists compression. This has the effect of keeping the optical elements parallel to each other.

I have compared my own Questar Seven to a 14\" Schmidt-Cassegrain on deep space objects such as the Sombrero galaxy, the Saturn Nebula, and Omega Centauri. While the 14\" scope was brighter on the fainter objects, the superior contrast and resolution of the Questar Seven was easily visible . . . even to the owner of the 14\" scope. The Crêpe Ring and Encke's Division in the rings of Saturn are routine with a Seven in good seeing, as are myriad whorls and festoons in Jupiter's belts and hundreds of sub-kilometer craters on the lunar surface.\u003c\/p\u003e\n\u003cp\u003eWhat is it about a Questar that lets it outperform larger scopes on a day in\/day out basis?\u003c\/p\u003e\n\u003cp\u003eSimply this: a fanatical devotion to hand-crafted accuracy.\u003c\/p\u003e\n\u003cp\u003eEach optical element in a Questar typically tests out at a truly outstanding 1\/50th wave accuracy (shaped to within four ten-millionths of an inch of perfection!) This produces guaranteed total system performance at the Cassegrain focus of 1\/8th wave or better. That's twice the accuracy needed to meet Lord Rayleigh's Criterion, which specifies the level of optical excellence required to yield visual performance that is indistinguishable from perfect optics.\u003c\/p\u003e\n\u003cp\u003eMost commercial telescopes claim to be \"diffraction-limited\" (which is generally assumed to mean 1\/4th wave accuracy). However, they do not specify whether that is for individual components or the system as a whole. In either case, it's a far cry from the 1\/8th wave \u003cem\u003etotal system accuracy \u003c\/em\u003eat the eyepiece of a Questar.\u003c\/p\u003e\n\u003cp\u003eThis significant difference in total system accuracy is one reason why a 7\" Questar can routinely outresolve a 14\" Schmidt-Cassegrain (or virtually any other larger aperture catadioptric or reflector scope) on globular clusters, binary stars, and lunar and planetary details - with the Questar invariably exceeding Dawes' limit for the best resolution available from an optical system of its aperture.\u003c\/p\u003e\n\u003cp\u003eA second reason is the turbulent Earth atmosphere all telescopes must look through. In essence, when observing, you are usually looking through bubbles of disturbed air - microcells typically 4\" in diameter in the layer of the atmosphere nearest the surface of the Earth. The larger the aperture of the scope, the greater the image-blurring effect of these microcells, as the larger scopes simply have to look through more of these turbulent cells than a smaller scope.\u003c\/p\u003e\n\u003cp\u003eFinally, there is the matter of contrast. The small secondary mirror of a Questar Seven Maksutov (only 1.87\" in diameter) scatters far less light than a 14\" Schmidt-Cassegrain's much larger 4.5\" secondary. The same holds true with any other larger reflector or catadioptric telescope you care to name. They all have larger light-scattering secondary or diagonal mirror obstructions than a 7\" Questar Astro. In addition, a Questar's central baffle tube is not merely black plastic or painted black to reduce reflections, as with lesser scopes, but is a centerless ground stainless steel tube, anodized matte black and containing a wire helix with 19 internal knife-edge baffles to eliminate low-angle reflections that no paint alone can stop. The result is that a Questar scatters less light from the bright areas of an image into the dark - crisply defining high contrast planetary and lunar details that a larger scope can wash out in a haze of scattered light.\u003c\/p\u003e\n\u003cp\u003eA large aperture scope does have greater light-gathering than a 7\" Questar to capture additional faint deep space objects from a dark sky site. However, the higher contrast of a Questar lets the multitude of galaxies and nebulas within its grasp stand out more distinctly against a darker sky background, particularly from light-polluted suburban or city sites where a larger scope's greater light-gathering capacity submerges subtle low-contrast deep space details in a fog of city light.\u003c\/p\u003e\n\u003cp\u003eAs a Rolls-Royce is to automobiles, so is a Questar to telescopes - the very finest hand-crafted optical performance that money can buy.\u003c\/p\u003e\n\u003cp\u003eThe Questar Astro is precision-fabricated of lightened aluminum and titanium components, black and blue anodized for long life. It has a 1\" diameter knurled anodized aluminum focusing knob on the rear cell. The knob focuses the scope by turning a spring-loaded 32-pitch stainless steel focus rod that acts directly on the mirror thimble to move the primary mirror within the optical tube. A precision linear rotor bearing, integrated with the mirror mounting, is matched to central tube thimble to minimize mirror shift when focusing.\u003c\/p\u003e\n\u003cp\u003eThe Seven Astro uses a 7\" diameter meniscus corrector lens of Grade A BK7 optical glass, with magnesium fluoride anti-reflection coatings for high light transmission and minimal reflected light loss. The 7.6\" diameter primary mirror is Pyrex, aluminized, with a silicon monoxide (quartz) overcoating for long life.\u003c\/p\u003e\n\u003cp\u003eThe Questar Astro comes with a 2\" mirror star diagonal (with a 1.25\" eyepiece adapter for Questar Brandon eyepieces) that threads onto the rear cell. A swivel coupling allows the eyepiece\/diagonal combination to be tilted from side to side to the most comfortable observing position. A 1.25\" Questar Brandon eyepiece is supplied with the scope to get you started observing. It provides a magnification of 100x and a 0.53° field of view that's a little larger in diameter than the full Moon. A dust cap and thread-on lens shade are standard, as is a hard carrying case. The Questar Seven Astro optical tube uses the well-known TeleVue Starbeam red dot unity-power illuminated finder that makes pointing a telescope as easy as pointing your finger.\u003c\/p\u003e\n\u003cp\u003eThe Questar Astro weighs 19 pounds (with diagonal and eyepiece in place, 21 pounds if you add the thread-on dew shield). It measures 17.6\" long (21.9\" with the star diagonal in place). The low profile mounting adapter block on the underside of the Astro has both 1\/4\"-20 and 3\/8\"-16 mounting holes to allow to be installed on the Questar Equatorial Fork Mount (our part #20004) and Questar Large Astro Pier (our part #29338) for astronomical use. It is well-balanced and relatively light, allowing it to be mounted on any suitably sturdy tripod for terrestrial operation. It can also be adapted to your own equatorial mount with minimal effort.\u003c\/p\u003e\n\u003cp\u003eA useful upgrade to consider would be to substitute a broadband coatings package on the optics in lieu of the standard magnesium fluoride coatings. This optional dielectric multicoatings package includes ultra-high transmission\/low reflectivity broadband dielectric multicoatings on both sides of its objective lens for a light loss of less than 1\/10th of 1% per surface for the brightest possible images. This compares with a light loss of 1% per surface with standard magnesium fluoride antireflection coatings. This multicoatings package also includes high reflectivity silver mirror coatings with a protective overcoating of thorium fluoride instead of standard aluminum coatings with a silicon monoxide overcoat. The broadband coatings package gives you a full 22% overall gain in light transmission and contrast that's very useful for photography and when viewing faint deep space objects.\u003c\/p\u003e\n\u003cp\u003eThis broadband coatings package is not recommended if you live full time on ocean-front property, or spend much of the year at the seaside. Constant exposure to salt air can adversely affect the silver mirror coatings. Occasional visits to the shore are not a problem, only extended stays (particularly if the scope is not packed away in its case when not in use). Adding a few packets of desiccant (silica gel or similar, available at most camera stores) to the case to absorb moisture when near large bodies of salt water would be a helpful preventative measure in any event.\u003c\/p\u003e\n\u003cp\u003eA thermally stable Zerodur ceramic mirror is also available as an option in place of the standard Pyrex mirror. As with any Pyrex mirror telescope, if the difference in temperature between indoors and outdoors is 30 degrees or more when a Questar is taken outside, minor refocusing will be required as its mirror contracts while cooling down to the outdoor air temperature. Some people find the need for even an occasional refocusing to be annoying. Since a Zerodur mirror exhibits virtually no expansion or contraction as temperatures change, this option eliminates this need for refocusing. This option is well worth considering due to the large thermal mass of the 7\" mirror and its consequently longer cool-down time than a smaller scope. I have both broadband coatings and a Zerodur mirror on my Questar Seven and can recommend them without reservation.\u003c\/p\u003e\n\u003cp\u003eThe Questar Seven Astro comes in a high impact ABS plastic sealed carrying case. A basic 35mm camera coupling set is also included (needs a Questar T-ring to connect to your camera).\u003c\/p\u003e\n\u003cp\u003eThis Questar is protected by a ten-year Questar warranty (two-year warranty on the focuser mechanism).\u003c\/p\u003e\n\u003cp\u003eAbsolutely pinpoint resolution, total freedom from spurious color and distortion, with an image clarity and contrast in a class all its own - a Questar is truly the Rolls-Royce of telescopes.

The rear element is hard multicoated low dispersion flint glass. The combination of fluorite crystal and low dispersion glass provide absolutely superb apochromatic color correction that is visibly better than any ED glass doublet scope. Color correction is on a par with far more costly triplet systems, but the light transmission is higher than any triplet apochromatic system, due to the smaller number of optical elements to scatter and absorb light.

Of course, we can't guarantee you'll be able to reach this kind of magnification level with any sort of regularity with this Takahashi (it would take the equivalent of a 1.5mm eyepiece and would produce a very dim 0.25mm exit pupil), but the possibility of very high magnification is there.\u003c\/p\u003e\n\u003cp\u003eThe smooth Takahashi rack and pinion focuser has large ribbed focusing knobs that are easy to grip and operate in cold weather, even when wearing gloves. The optical tube has a flat boss above the focusing knobs, with two mounting bolts to hold an optional finderscope, such as the straight-through Takahashi 5 x 25mm with its very wide 9° field. The supplied 1.25\" eyepiece holder uses a non-marring nylon split compression ring system to hold your star diagonal or eyepiece in place. This system won't scratch the barrel of your eyepiece or star diagonal, as an ordinary brass or steel thumbscrew can. A simple twist of the ribbed ring at the end of the focuser drawtube tightens the internal compression ring to hold your diagonal firmly in place; while a twist in the opposite direction lets you remove it with ease.\u003c\/p\u003e\n\u003cp\u003eThe Takahashi optical tube itself weighs less than three lbs. It measures only 17\" long with dew shield in place. The optical tube is 80mm in diameter and an optional tube holder is available to fit the scope on a Takahashi mount (such as the altazimuth #TGS01 or the very compact #TGUL Teegul Sky Patrol equatorial).\u003c\/p\u003e\n\u003cp\u003eThe 60mm Takahashi FS-60C.

I have compared my own Questar Seven to a 14\" Schmidt-Cassegrain on deep space objects such as the Sombrero galaxy, the Saturn Nebula, and Omega Centauri. While the 14\" scope was brighter on the fainter objects, the superior contrast and resolution of the Questar Seven was easily visible . . . even to the owner of the 14\" scope. The Crêpe Ring and Encke's Division in the rings of Saturn are routine with a Seven Classic in good seeing, as are myriad whorls and festoons in Jupiter's belts and hundreds of sub-kilometer craters on the lunar surface.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eWhat is it about a Questar that lets it outperform larger scopes on a day in\/day out basis?\u003c\/p\u003e\n\u003cp\u003eSimply this: a fanatical devotion to hand-crafted accuracy.\u003c\/p\u003e\n\u003cp\u003eEach optical element in a Questar typically tests out at a truly outstanding 1\/50th wave accuracy (shaped to within four ten-millionths of an inch of perfection!) This produces guaranteed total system performance at the Cassegrain focus of 1\/8th wave or better. That's twice the accuracy needed to meet Lord Rayleigh's Criterion, which specifies the level of optical excellence required to yield visual performance that is indistinguishable from perfect optics.\u003c\/p\u003e\n\u003cp\u003eMost commercial telescopes claim to be \"diffraction-limited\" (which is generally assumed to mean 1\/4th wave accuracy). However, they do not specify whether that is for individual components or the system as a whole. In either case, it's a far cry from the 1\/8th wave \u003cem\u003etotal system accuracy \u003c\/em\u003eentering the eyepiece of a Questar.\u003c\/p\u003e\n\u003cp\u003eThis significant difference in total system accuracy is one reason why a 7\" Questar can routinely outresolve a 14\" Schmidt-Cassegrain (or virtually any other larger aperture catadioptric or reflector scope) on globular clusters, binary stars, and lunar and planetary details - with the Questar invariably exceeding Dawes' limit for the best resolution available from an optical system of its aperture.\u003c\/p\u003e\n\u003cp\u003eA second reason is the turbulent Earth atmosphere all telescopes must look through. In essence, when observing, you are usually looking through bubbles of disturbed air - microcells typically 4\" in diameter in the layer of the atmosphere nearest the surface of the Earth. The larger the aperture of the scope, the greater the image-blurring effect of these microcells, as the larger scopes simply have to look through more of these turbulent cells than a smaller scope.\u003c\/p\u003e\n\u003cp\u003eFinally, there is the matter of contrast. The small secondary mirror of a Questar Seven Maksutov (only 1.87\" in diameter) scatters far less light than a 14\" Schmidt-Cassegrain's much larger 4.5\" secondary. The same holds true with any other larger reflector or catadioptric telescope you care to name. They all have larger light-scattering secondary or diagonal mirror obstructions than a 7\" Questar Classic Titanium. In addition, a Questar's central baffle tube is not merely black plastic or painted black to reduce reflections, as with lesser scopes, but is a centerless ground stainless steel tube, anodized matte black and containing a wire helix with 19 internal knife-edge baffles to eliminate low-angle reflections that no paint alone can stop. The result is that a Questar scatters less light from the bright areas of an image into the dark - crisply defining high contrast planetary and lunar details that a larger scope can wash out in a haze of scattered light.\u003c\/p\u003e\n\u003cp\u003eA large aperture scope does have greater light-gathering than a 7\" Questar to capture additional faint deep space objects from a dark sky site. However, the higher contrast of a Questar lets the multitude of galaxies and nebulas within its grasp stand out more distinctly against a darker sky background, particularly from light-polluted suburban or city sites where a larger scope's greater light-gathering capacity submerges subtle low-contrast deep space details in a fog of city light.\u003c\/p\u003e\n\u003cp\u003eAs a Rolls-Royce is to automobiles, so is a Questar to telescopes - the very finest hand-crafted optical performance that money can buy.\u003c\/p\u003e\n\u003cp\u003eThe Questar Classic Titanium is precision-fabricated of specially lightened aluminum and titanium, with a black and blue anodized finish for long life. Questar engaged in an extensive heat transfer analysis to refine the shaping and milling of the internal components to dissipate heat and rapidly bring the optics down to ambient temperature quickly. This was done to avoid having to resort to the use of powered fans to cool the optics as others do (which can suck image-degrading dust into the optical path).\u003c\/p\u003e\n\u003cp\u003eAll internal components (such as the main tube mounting plate, mirror thimble, and central light baffle tube) are titanium, with milled surfaces to increase heat transfer and lighten weight. The optical tube is extruded and stress-relieved aluminum. The control box is machined cast aluminum, with milled internal surfaces to increase heat transfer and lighten weight. It is externally painted with special aluminum paint and clear overcoated for durability. The interior is finished in anti-reflective matte black paint.\u003c\/p\u003e\n\u003cp\u003eThe control knobs on the rear cell are turret lathe-turned anodized aluminum, with sharts and control levers of stainless steel. The focus knob focuses the scope by turning a spring-loaded 1\/4\"-32 thread stainless steel focus rod that acts directly on the titanium mirror thimble to move the primary mirror along the titanium central baffle tube within the optical tube. A precision linear ball-type bearing, integrated with the mirror mounting, is matched to central tube thimble to minimize mirror shift when focusing.\u003c\/p\u003e\n\u003cp\u003eThe optical tube barrel of the Questar Seven Classic Titanium is wrapped with an accurate full-color silk-screened star chart. The thread-on dewcap is wrapped with a useful silk-screened map of the Moon.\u003c\/p\u003e\n\u003cp\u003eThe Seven Classic Titanium uses a 7\" diameter meniscus corrector lens of Grade A BK7 optical glass, with magnesium fluoride anti-reflection coatings for high light transmission and minimal reflected light loss. The 7.6\" diameter primary mirror is Pyrex, aluminized, with a silicon monoxide (quartz) overcoating for long life.\u003c\/p\u003e\n\u003cp\u003eInsert the Questar's premium 24mm 1.25\" Questar Brandon eyepiece into the eyepiece holder on the top of the control box at the rear of the scope. Look in and you're looking into a 7.6x finder with a wide 7° field. A finger touch on a convenient lever at the rear of the scope changes the finder into a 106x telescope for observing the Moon, nebulas, galaxies, and star clusters. Touch a second lever and a built-in 2x Dakin Barlow instantly increases that eyepiece power to 212x for closer observing. Exchange the 24mm eyepiece for the supplied 16mm 1.25\" Questar Brandon eyepiece and you extend the power range still further, to an 11.5x finder with a 4.6° field and a 159x and 318x telescope. You never have to worry about the telescope and finderscope getting out of alignment with each other, because the finderscope in an integral part of the telescope body itself. Optional higher and lower power 1.25\" Questar Brandon eyepieces are available, for magnifications as low as 63.5x and as high as 635x.\u003c\/p\u003e\n\u003cp\u003eIn addition, the Questar Classic Titanium can be equipped with an optional 2\" mirror star diagonal that threads onto the rear cell. This lets you use longer focal length 2\" Brandon and third party eyepieces to lower the magnification to as little as 45x.\u003c\/p\u003e\n\u003cp\u003eThe Questar Classic Titanium weighs 19 pounds, 21 pounds if you add the thread-on dew shield). It measures 22.6\" long. The low profile mounting adapter block on the underside of the Classic Titanium has both 1\/4\"-20 and 3\/8\"-16 mounting holes to allow to be installed on the Questar Equatorial Fork Mount (our part #20004) and Questar Large Classic Titanium Pier (our part #29338) for astronomical use. It is well-balanced and relatively light, allowing it to be mounted on any suitably sturdy tripod for terrestrial operation. It can also be adapted to your own equatorial mount with minimal effort.\u003c\/p\u003e\n\u003cp\u003eThis Questar Seven Classic Titanium has a broadband dielectric multicoatings package that includes ultra-high transmission\/low reflectivity broadband dielectric multicoatings on both sides of its objective lens for a light loss of less than 1\/10th of 1% per surface for the brightest possible images. This compares with a light loss of 1% per surface with standard magnesium fluoride antireflection coatings. This multicoatings package also includes high reflectivity silver mirror coatings with a protective overcoating of thorium fluoride instead of standard aluminum coatings with a silicon monoxide overcoat. The broadband coatings package gives you a full 22% overall gain in light transmission and contrast that's very useful for photography and when viewing faint deep space objects.\u003c\/p\u003e\n\u003cp\u003eThis broadband coatings package is not recommended if you live full time on ocean-front property, or spend much of the year at the seaside. Constant exposure to salt air can adversely affect the silver mirror coatings. Occasional visits to the shore are not a problem, only extended stays (particularly if the scope is not packed away in its case when not in use). Adding a few packets of desiccant (silica gel or similar, available at most camera stores) to the case to absorb moisture when near large bodies of salt water would be a helpful preventative measure in any event.\u003c\/p\u003e\n\u003cp\u003eA thermally stable Zerodur ceramic mirror is also available as an option in place of the standard Pyrex mirror. As with any Pyrex mirror telescope, if the difference in temperature between indoors and outdoors is 30 degrees or more when a Questar is taken outside, minor refocusing will be required as its mirror contracts while cooling down to the outdoor air temperature. Some people find the need for even an occasional refocusing to be annoying. Since a Zerodur mirror exhibits virtually no expansion or contraction as temperatures change, this option eliminates this need for refocusing. This option is well worth considering due to the large thermal mass of the 7\" mirror and its consequently longer cool-down time than a smaller scope. I have both broadband coatings and a Zerodur mirror on my Questar Seven and can recommend them without reservation.\u003c\/p\u003e\n\u003cp\u003eThe Questar Seven Classic Titanium comes in a high impact ABS plastic sealed carrying case with wheels and transport handle. A basic 35mm camera coupling set is also included (needs a Questar T-ring to connect to your camera).\u003c\/p\u003e\n\u003cp\u003eThis Questar is protected by a ten-year Questar warranty (two-year warranty on the focuser mechanism and five years on the broadband coatings).\u003c\/p\u003e\n\u003cp\u003eAbsolutely pinpoint resolution, total freedom from spurious color and distortion, with an image clarity and contrast in a class all its own - a Questar is truly the Rolls-Royce of telescopes. For those individuals who appreciate the very finest that life has to offer, a Questar Seven Classic Titanium with broadband optical coatings will prove to be an absolutely eye-opening astronomical revelation.\u003c\/p\u003e\n\u003ch2\u003eTech Details: \u003c\/h2\u003e\n\u003ctable id=\"product-attribute-specs-table\" class=\"table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eAperture\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e7\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBinary and Star Cluster Observation\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eVery Good\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e2425mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/13.6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGalaxy and Nebula Observation\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eGood\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e19 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHighest Useful Magnification\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e423x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLunar Observation\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eGreat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e19 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePlanetary Observation\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eGood\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e0.65 arc seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVisual Limiting Magnitude\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e13.8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e10 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Questar","offers":[{"title":"Default Title","offer_id":40221647077449,"sku":"Q7CBT","price":12795.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/5514_1.jpg?v=1662967132"},{"product_id":"questar-7-classic-titanium-maksutov-cassegrain-broadband-coatings-quartz-mirror","title":"Questar 7\" Classic Titanium Maksutov-Cassegrain, Magnesium Fluoride AR and Silver Reflecting Coatings, Quartz Mirror","description":"\u003cp\u003eThis Questar Seven Classic Titanium uses the same quartz mirror and coatings combination as the renowned 50th Anniversary 3.5\" Questar, perhaps the ultimate small telescope.

The focus knob focuses the scope by turning a spring-loaded 1\/4\"-32 thread stainless steel focus rod that acts directly on the titanium mirror thimble to move the primary mirror along the titanium central baffle tube within the optical tube. A precision linear ball-type bearing, integrated with the mirror mounting, is matched to central tube thimble to minimize mirror shift when focusing.\u003c\/p\u003e\n\u003cp\u003eThe optical tube barrel of the Questar Seven Classic Titanium is wrapped with an accurate full-color silk-screened star chart. The thread-on dewcap is wrapped with a useful silk-screened map of the Moon.\u003c\/p\u003e\n\u003cp\u003eInsert the Questar's premium 24mm 1.25\" Questar Brandon eyepiece into the eyepiece holder on the top of the control box at the rear of the scope. Look in and you're looking into a 7.6x finder with a wide 7° field. A finger touch on a convenient lever at the rear of the scope changes the finder into a 106x telescope for observing the Moon, nebulas, galaxies, and star clusters. Touch a second lever and a built-in 2x Dakin Barlow instantly increases that eyepiece power to 212x for closer observing. Exchange the 24mm eyepiece for the supplied 16mm 1.25\" Questar Brandon eyepiece and you extend the power range still further, to an 11.5x finder with a 4.6° field and a 159x and 318x telescope. You never have to worry about the telescope and finderscope getting out of alignment with each other, because the finderscope in an integral part of the telescope body itself. Optional higher and lower power 1.25\" Questar Brandon eyepieces are available, for magnifications as low as 63.5x and as high as 635x.\u003c\/p\u003e\n\u003cp\u003eIn addition, the Questar Classic Titanium can be equipped with an optional 2\" mirror star diagonal that threads onto the rear cell. This lets you use longer focal length 2\" Brandon and third party eyepieces to lower the magnification to as little as 45x.\u003c\/p\u003e\n\u003cp\u003eThe Questar Classic Titanium weighs 19 pounds, 21 pounds if you add the thread-on dew shield). It measures 22.6\" long. The low profile mounting adapter block on the underside of the Classic Titanium has both 1\/4\"-20 and 3\/8\"-16 mounting holes to allow to be installed on the Questar Equatorial Fork Mount (our part #20004) and Questar Large Classic Titanium Pier (our part #29338) for astronomical use. It is well-balanced and relatively light, allowing it to be mounted on any suitably sturdy tripod for terrestrial operation. It can also be adapted to your own equatorial mount with minimal effort.\u003c\/p\u003e\n\u003cp\u003eThis Questar Seven Classic Titanium uses the same optical materials and coatings combination as the renowned 50th Anniversary 3.5\" Questar, perhaps the ultimate small telescope. The Seven Classic's zero thermal expansion quartz mirror eliminates the need to refocus the scope as it cools to ambient temperature in situations involving large temperature swings. With a conventional Pyrex mirror telescope, if the difference in temperature between indoors and outdoors is 30 degrees or more Fahrenheit when the scope is taken outside, minor refocusing will be required as its mirror contracts while cooling down to the outdoor air temperature. This is particularly true with a relatively large aperture scope like this Seven Classic, which has an oversize 7.6\" primary mirror. Some people find the need for even an occasional refocusing to be annoying. Since a quartz mirror exhibits no expansion or contraction as temperatures change, the quartz mirror in this Questar Seven Classic Titanium eliminates any need for even minor refocusing. You can take it out into the coldest night or hottest day and use it instantly, without any need for it to acclimate to the ambient temperature.\u003c\/p\u003e\n\u003cp\u003eThis Questar Seven Classic Titanium uses high reflectivity silver mirror coatings with a protective overcoating of thorium fluoride instead of a standard Questar's aluminum coatings with a silicon monoxide overcoat. The two silver mirrors provide a 10% light gain per surface, compared with aluminized mirrors. Magnesium fluoride antireflection coatings are used on the Grade A BK7 optical glass meniscus corrector lens on this scope, as mag fluoride coatings are optimally matched to the reflectivity response of the quartz\/silver\/thorium-coated mirrors.\u003c\/p\u003e\n\u003cp\u003eThis broadband coatings package is not recommended if you live full time on ocean-front property, or spend much of the year at the seaside. Constant exposure to salt air can adversely affect the silver mirror coatings. Occasional visits to the shore are not a problem, only extended stays (particularly if the scope is not packed away in its case when not in use). Adding a few packets of desiccant (silica gel or similar, available at most camera stores) to the case to absorb moisture when near large bodies of salt water would be a helpful preventative measure in any event.\u003c\/p\u003e\n\u003cp\u003eThe Questar Seven Classic Titanium comes in a high impact ABS plastic sealed carrying case with wheels and transport handle. A basic 35mm camera coupling set is also included (needs a Questar T-ring to connect to your camera).\u003c\/p\u003e\n\u003cp\u003eThis Questar is protected by a ten-year Questar warranty (two-year warranty on the focuser mechanism and five years on the broadband coatings).\u003c\/p\u003e\n\u003cp\u003eAbsolutely pinpoint resolution, total freedom from spurious color and distortion, with an image clarity and contrast in a class all its own - a Questar is truly the Rolls-Royce of telescopes. For those individuals who appreciate the very finest that life has to offer, a Questar Seven Classic Titanium with broadband optical coatings and a quartz mirror will prove to be an absolutely eye-opening astronomical revelation. It is a telescope you can live with comfortably for the rest of your life.\u003c\/p\u003e\n\u003ch2\u003eTech Details: \u003c\/h2\u003e\n\u003ctable class=\"table\" id=\"product-attribute-specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eAperture\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e7\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBinary and Star Cluster Observation\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eVery Good\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e2425mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/13.6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGalaxy and Nebula Observation\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eGood\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e19 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHighest Useful Magnification\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e423x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLunar Observation\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eGreat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e19 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePlanetary Observation\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eGood\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e0.65 arc seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVisual Limiting Magnitude\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e13.8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e10 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Questar","offers":[{"title":"Default Title","offer_id":40221647175753,"sku":"Q7CQT","price":14695.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/5516_1.jpg?v=1662967137"},{"product_id":"powerseeker-60-2-4-altazimuth-refractor","title":"Celestron PowerSeeker 60, 2.4\" Altazimuth Refractor  21041","description":"\u003cp\u003eThe Celestron PowerSeeker 60 altazimuth refractor is a \u003cem\u003every \u003c\/em\u003eeconomical introduction to casual astronomy and nature study for the backyard astronomer, but one that can supply good images of nature, the Moon, the planets, and many of the brighter deep space objects.\u003c\/p\u003e\n\u003cp\u003eThe 60mm altazimuth Celestron PowerSeeker is a good choice for a beginning astronomer who also has an eye for nature.

Both eyepieces have antireflection coatings on their lens surfaces for sharp images and good contrast. The 4mm eyepiece is realistically beyond the scope's usable magnification limit on all but the very rare nights of absolutely perfect seeing conditions. An optional 9mm eyepiece comes closer to providing the highest useful power on a regular basis.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBarlow lens:\u003c\/strong\u003e A 1.25\" 3x Barlow lens is included that triples the magnification of the two supplied eyepieces to 135x and 675x. The 675x magnification of the 4mm eyepiece\/Barlow combination is far beyond the scope's usable magnification capability, however. Do not count on using that optical combination very often, if at all. A lower power eyepiece, such as a 40mm (22.5x; 67.5x with the Barlow), would provide a pair of magnifications more useful than the impractical 675x of the 4mm and Barlow combination.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFinderscope:\u003c\/strong\u003e A low power 5x24mm finderscope attaches to the side of the optical tube. The straight-through viewing refractor finderscope provides a traditional inverted mirror-image astronomical view. If properly collimated (aligned) with the view through the main telescope, its crosshairs will help you center distant objects in the telescope so you don't have to search for them using the narrow eyepiece field of view.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Telescope's Mount . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEquatorial mount:\u003c\/strong\u003e The German equatorial mount is designed for astronomical observing. By aligning the mount on the north celestial pole, you only need to turn one slow motion control knob to follow planets and stars as they travel across the sky. A counterweight on the opposite side of the mount from the telescope balances the weight of the optical tube and makes it easy to move the scope effortlessly from one part of the sky to another.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSetting circles:\u003c\/strong\u003e Setting circles (graduated scales marked in either hours and minutes or degrees) are provided in both right ascension (the east\/west position of objects in the sky measured in hours and minutes) and declination (the north\/south position measured in degrees). These allow you to align the scope on the approximate position of an object in the sky by using its r. a. and dec coordinates from a star chart - before you search for it in the finderscope and eyepiece. Setting circles can reduce the time it takes for you to find the fainter and more difficult deep space objects.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eManual slow motion controls:\u003c\/strong\u003e There are two slow motion control knobs connected to the mount by long flexible cables so they are easy to reach while observing. One controls the scope's motion in right ascension (the east\/west direction in the sky). Turning this knob enables you to follow the motion of celestial objects as they travel from east to west across the sky.\u003c\/p\u003e\n\u003cp\u003eThe second controls the scope's motion in declination (the north\/south direction in the sky). Turning this knob enables you to correct for any north\/south drift a celestial object may take as it drifts across the sky, due to an improper alignment of the scope on the north celestial pole when you first set it up.\u003c\/p\u003e\n\u003cp\u003eThe two controls combine to give you complete access to any part of the sky. They give you the ability to star hop from a known object to any other object by using a star chart.

That means visibly brighter deep space images and the ability to see many more faint objects than a 60mm scope could ever hope to show.

That's the equivalent of a 7\" reflector in terms of the amount of light that reaches your eyepiece. With 459 times the light-gathering capacity of the human eye, the optics are sharp and well suited to serious deep space observing of binary stars, star clusters, and the brighter nebulas and galaxies, in addition to excellent high contrast planetary and lunar images. The objective lens cell is fully collimatable, using push\/pull collimation screws, so you can optimize your image quality.\u003c\/p\u003e\n\u003cp\u003eSome chromatic aberration is visible on stars and objects of 2nd or 3rd magnitude and brighter, as you would expect in an achromatic refractor of such large aperture and fast focal ratio. However, the spurious color is well controlled and not unreasonable, thanks to careful optical design, and has little effect on deep space observing. Most observers feel the relatively limited amount of chromatic aberration visible is a small price to pay for the scope's many other virtues of sharpness, contrast, and optical clarity.\u003c\/p\u003e\n\u003cp\u003eFor peak performance, some observers have found that upgrading the supplied star diagonal to a premium version, such as the Astronomy Technologies #AT1D dielectric diagonal, pays visible dividends in sharpness and contrast during high magnification observing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetails About This Optical Tube . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAchromatic refractor optics:\u003c\/strong\u003e 6\" (150mm) aperture, 1200mm focal length, f\/8 air-spaced crown and flint glass doublet lens.

This effectively reduces the aperture to 4\" and converts the telescope to an f\/12 focal ratio. At this longer focal ratio, chromatic aberration is reduced, with only a modest loss in resolution.

The latest antireflection multicoatings and numerous knife-edge internal baffles assure the maximum image contrast possible. \u003cbr\u003eThis 5.1\" Takahashi has a large aperture and diffraction-free images that make it surprisingly good for much deep space observing, as well. Binary stars and globular star clusters are particularly well-resolved and vivid, with the contrasting colors of many binary systems showing nicely.

The transit made me realize that the TV-60 just might be the ultimate scope for eclipse chasers . . . As I have come to expect from observing with TeleVue's other short-focus apo refractors, the views with the TV-60 are essentially free of false color . . . Even at 120x, brilliant Vega, one of the most challenging stars for a refractor to image cleanly, appears as a blue-white Airy disk surrounded by several white diffraction rings and no perceptible color halo . . .\u003c\/p\u003e\n\u003cp\u003e\"After many nights of observing, I'm comfortable recommending an upper limit of 180x for the TV-60, which is 75x per inch of aperture. I achieved this magnification with the 2-mm setting on the TeleVue 2-to-4-mm Nagler Zoom eyepiece. It offered exceptional views of binary stars (especially the well-known Double-Double in Lyra) and the Moon . . .\u003c\/p\u003e\n\u003cp\u003e\"The pint-sized TV-60 could match the best high-power view I have ever seen in a quality 60-mm f\/15 refractor. And the TV-60 could do something those other scopes couldn't: offer a stunning wide-field experience . . . With just three eyepieces - the 24mm Panoptic and the 9- and 2.5-mm Naglers - I spent hours wandering the Milky Way from Sagittarius to Cassiopeia.\"\u003c\/p\u003e\n\u003cp\u003eThis Telescope's Optical and Mechanical Systems . . .\u003c\/p\u003e\n\u003cp\u003eApochromatic SD doublet optics: 2.4\" (60mm) aperture, 360mm focal length, f\/6 apochromatic doublet lens using an SD (Special Dispersion) glass element.

Nylon thumbscrews lock in the drawtube focus and hold optional 1.25\" optical accessories securely in place.\u003c\/p\u003e\n\u003cp\u003eDew shield: The scope comes with a sliding captive dew shield to slow the formation of dew and act like a camera lens shade to improve contrast by blocking ambient light (from a neighbor's back yard security light, for example.) A camera-style snap-in plastic dust cap protects the optics from damage while stored or traveling.\u003c\/p\u003e\n\u003cp\u003eStar diagonal: No star diagonal is supplied, as most observers buy the TV-60 as a second 'grab and go' scope and therefore already have a star diagonal from their primary telescope. This allows you to equip the TV-60 with the optical accessories that best suit your observing style - such as an in-line Porro prism or a 45º image erecting diagonal for terrestrial observing, or a 60º or 90º star diagonal for astronomical use.\u003c\/p\u003e\n\u003cp\u003eEyepiece: As with a star diagonal, none is supplied, as it is assumed that the buyer already has a selection of eyepieces from his or her primary scope. A good optional basic eyepiece might be TeleVue's 11mm Plössl. This premium eyepiece provides a magnification of 33x, with a field of view more than three times as wide as the full Moon. Optional shorter focal length eyepieces and\/or Barlow lenses will provide high powers to let you examine details in the storm belts of Jupiter, the rings of Saturn, the mountains of the Moon, and much more. And the resolution of those details will be crisp and detailed, often visibly superior to larger telescopes more easily affected by atmospheric conditions. The maximum power for lunar\/planetary viewing is 180x, with the optional 2-4mm Nagler Zoom. Put in an optional longer focal length (lower power) eyepiece and the TV-60 becomes a true rich field telescope, capable of scanning wide scenic vistas by day and revealing multitudes of large, faint deep space objects by night. With an optional 1.25\" 40mm TeleVue Plössl (9x, with a 4.3° field), the TV-60 is not only a surprisingly good little rich field scope, but it is its own best finderscope, as well. It's also excellent as a terrestrial spotting scope for vacations, birding, or nature studies. In addition, optional camera adapters turn the TV-60 into excellent 360mm (7.2x) f\/6 telephoto lens for terrestrial and lunar photography.\u003c\/p\u003e\n\u003cp\u003eFinderscope: No finderscope is supplied or needed. As noted above, with a 40mm TeleVue Plössl eyepiece, the TV-60 its own best finderscope.\u003c\/p\u003e\n\u003cp\u003eMounting system: The TV-60 has an adjustable dovetail balancing bar mount that fits on any optional sturdy photo tripod for casual use, or on an optional equatorial or altazimuth mount (such as the TeleVue Tele-Pod and Panoramic mounts and the Vixen\/TeleVue PORTA mount) for more serious observing. An available optional X-Y axis adjustable mounting bracket (#TVXYA) allows the TV-60 to be used as a superfinder on TeleVue refractors, while a separate adapter (#TVXYC) allows it to be used on Celestron and Meade Schmidt-Cassegrain telescopes, as well as on TeleVue scopes. The balancing bar system allows the TV-60 to be moved fore and aft on your mount or tripod to balance the weight of different eyepieces or a camera.\u003c\/p\u003e\n\u003cp\u003eThere are few optical systems that combine into one very compact body the ability to be customized into a serious astronomical telescope with true apochromatic optics, a terrestrial spotting scope, and a top-quality telephoto lens - but the TV-60 does it surprisingly well. Whether you want to observe the skies from your back yard on the spur of the moment, or travel round the world with a very portable telescope that will reveal and photograph everything nearby and distant, you'll find it hard to beat this truly exceptional TeleVue small refractor.\u003c\/p\u003e\n\u003ch2\u003eTech Details: \u003c\/h2\u003e\n\u003ctable id=\"product-attribute-specs-table\" class=\"table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eAperture\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e2.4\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e360mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e3 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHighest Useful Magnification\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e180x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e3 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e1.93 arc seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTelescope Type\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eRefractor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVisual Limiting Magnitude\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e11.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e5 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eSupplied Accessories: \u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e60mm apochromatic doublet optics\u003c\/li\u003e\n\u003cli\u003e2-stage drawtube\/helical focuser\u003c\/li\u003e\n\u003cli\u003eRetractable lens shade\u003c\/li\u003e\n\u003cli\u003eDust covers\u003c\/li\u003e\n\u003cli\u003eCarrying pouch\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TeleVue","offers":[{"title":"Default Title","offer_id":40221657858121,"sku":"TV60","price":867.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/files\/TVO_2460_TV60ota_layout_v4copy.jpg?v=1723750815"},{"product_id":"8-sct-optical-tube-cge-losmandy-dovetail","title":"Celestron 8\" SCT Optical Tube, CGE\/Losmandy Dovetail","description":"\u003cp\u003eThe Celestron C8 was the first Schmidt-Cassegrain telescope available to amateur astronomers.

Hand figuring the optical system is a complex optical procedure done on a commercial basis only by Celestron. Four separate optical tests are made on every set of optics, using a double-pass laser autocollimator - an Airy disc inspection, a test for spherical aberration by examining the diffraction images on both sides of focus, a Ronchi grating test, and a knife edge test. A skilled optician evaluates these tests. He then fabricates a precision pitch lap and delicately hand polishes the secondary mirror to compensate for any small residual zonal defects and smooth the optical figure. Done a few strokes at a time, and testing constantly to evaluate their effect, this final hand-figuring can take hours.

Just point at three bright stars - \u003cem\u003eany\u003c\/em\u003e three! - and this talented go-to XLT-multicoated Schmidt-Cassegrain will do the finding for you . . .\u003c\/p\u003e\n\u003cp\u003eIf you can see three bright stars, or two bright stars and a planet (you don't even have to know which stars and planet you're looking at), the Celestron CPC 9¼ XLT with state-of-the-art XLT multicoatings will line itself up on the sky and show you over 40,000 stars, deep space objects, and solar system objects - all automatically! The CPC 9¼ XLT is an easily-portable fully computerized go-to Schmidt-Cassegrain telescope with a built-in 16-channel GPS (satellite-based Global Positioning System) receiver. The GPS system and Celestron's revolutionary new SkyAlign technology take the guesswork and effort out of aligning the scope on the sky to find deep space and solar system objects.\u003c\/p\u003e\n\u003cp\u003eMany observers consider Celestron's 9.25\" optics to be the best currently available in a Schmidt-Cassegrain design. Contrast is above average for its optical type, and its resolution is 15% better than an 8\" scope, for more detailed lunar, planetary, and globular cluster images. With a light grasp about 1127 times that of even the sharpest dark-adapted eye (a third greater than an 8\" scope), the CPC 9¼ XLT can reveal to you star clusters, nebulas, planets, and galaxies in amazing detail. The CPC 9¼ XLT is a significant step up from an 8\" scope in performance, without any significant penalty in cost, size, or weight. Its light weight, easy assembly, and intuitive computer control make using it a pleasure - either in your back yard or at a distant dark sky site.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Telescope's Optical System . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSchmidt-Cassegrain optical tube:\u003c\/strong\u003e 9.25\" aperture (2350mm focal length f\/10). Guaranteed diffraction-limited optical performance. The 9.25\" aperture gathers 33% more light than an 8\" scope, providing brighter images of faint deep space objects. The CPC 9¼ XLT has an optimized baffle system that improves astrophotography by minimizing vignetting at the corners of a 35mm negative. Its longer primary focal length and lower magnification secondary mirror produce a flatter field of view at the focal plane. This helps to reduce optical aberrations during photography and when using wide field long focal length 2\" eyepieces.

Starbright XLT multicoatings give you higher light transmission for brighter visual deep space images and shorter exposure times during photography. They also visibly increase the contrast on subtle lunar, planetary, and nebula details when compared with a scope with standard coatings or multicoatings.

(Jupiter's) belts were simply dazzling, with subtle colors and the most tenuous detail seen steadily . . . (Saturn's) rings were very impressive, and both Cassini's Division and the C ring were easily visible . . . Deep sky objects were no less appealing . . . the Orion Nebula was wonderful, showing its gossamer clouds in all sorts of intricate contortions. Buried within the clouds, all four stars of the Trapezium sparkled, and even the more challenging E and F Trapezium members shown through . . .

A large 9.8\" azimuth bearing provides ultra-stable and smooth polar axis motion. The 5.625\" diameter 180-tooth hard-anodized altitude and azimuth drive gears are driven by brass worms to provide smooth slewing and tracking, with 9 user-selectable speeds from 3° per second slewing down to a precise 0.5x sidereal rate for photographic drive correction. The drives work in the altazimuth mode (right\/left up\/down) to locate and track objects for visual use and casual solar system photography. If long exposure deep space photography is planned, the scope can be converted to equatorial operation by adding an optional wedge.\u003c\/p\u003e\n\u003cp\u003eThe scope includes three preprogrammed drive speeds - sidereal, solar, and lunar. It operates in an altazimuth mode, as well as northern hemisphere equatorial and southern hemisphere equatorial (using an optional equatorial wedge).\u003c\/p\u003e\n\u003cp\u003eThe scope is powered by external 12 Volt 1.5 Amp DC power (a car battery or optional rechargeable 12V battery #4512V or #4517V). The scope cannot be powered by short-lived flashlight batteries. The standard equipment car battery cord and optional AC adapter plug into the drive base. Power and command signals to the declination motor are routed through cordless internal slip ring signal paths. There's no separate external declination cable to connect the drive base to the dec motor as with other scopes, so you don't have to worry about losing a cable or breaking it by tangling the cable around the scope inadvertently while observing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNexStar Computer:\u003c\/strong\u003e The scope's NexStar computer can show you the planets and thousands of deep space objects the very first night you use your scope - even if you've never used a telescope before!

Simply mount the scope on its tripod and turn on the power. The built-in 16-channel GPS system uses signals from government satellites to calculate the scope's location on earth with an accuracy measured in meters. The system also calculates the current time based on the split second accuracy of the GPS time signals. After quickly doing all these calculations for you automatically (you don't have to enter any information manually), the SkyAlign software in the scope's hand control signals you to point the scope at any three bright stars (you don't have to point at specific known stars). Using the scope's hand control, center the stars in the finderscope crosshairs. You can even point at two stars and a planet or the Moon, if you prefer. The scope will then be ready to find and track over 45,000 objects for you at your command.\u003c\/p\u003e\n\u003cp\u003eIf you're using an optional equatorial wedge to polar align the scope for long exposure astrophotography, a polar alignment program in the scope's computer makes quick work of accurate alignment on the north celestial pole.

The system also calculates the current time based on the split second accuracy of the GPS time signals. After quickly doing all these calculations for you automatically (you don't have to enter any information manually), the SkyAlign software in the scope's hand control signals you to point the scope at any three bright stars (you don't have to point at specific known stars). Using the scope's hand control, center the stars in the finderscope crosshairs. You can even point at two stars and a planet or the Moon, if you prefer.

The 11-inch aperture has enough light-gathering ability to give an inspiring view of the night sky. Usually, a large aperture means the scope is more difficult to set up and, for some observers, too heavy. But the CPC 1100 is easy to handle, attractive, and nicely engineered. But most important - to me, at least - is the fact that its images are superb.\"\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTwo-year warranty:\u003c\/strong\u003e All Celestron go-to telescopes have a two-year warranty. \u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable id=\"product-attribute-specs-table\" class=\"table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eAperture\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e11\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e2800mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e65 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHighest Useful Magnification\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e560x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMotorized Controls\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eComputerized GoTo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e84 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOptical Coatings\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eStarBright XLT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e0.41 arc seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied Eyepiece\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e40mm 1.25\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTelescope Type\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eSchmidt-Cassegrain\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eView Finder\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e8x50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVisual Limiting Magnitude\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e14.7\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e2 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eSupplied Accessories: \u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e11\" f\/10 Starbright XLT multicoated optics in aluminum tube\u003c\/li\u003e\n\u003cli\u003eGo-to fully computerized dual fork arm mount with 5.625\" worm gears in each axis and carrying handles\u003c\/li\u003e\n\u003cli\u003eHeavy duty adjustable height metal tripod\u003c\/li\u003e\n\u003cli\u003eNexStar 40,000+ object computer hand control with SkyAlign three-star alignment, plus auto two-star align, one-star align, EQ align, and solar system align\u003c\/li\u003e\n\u003cli\u003ePPEC (Permanent Periodic Error Compensation)\u003c\/li\u003e\n\u003cli\u003eRS-232 port for connection to a PC\u003c\/li\u003e\n\u003cli\u003eSeparate CCD autoguider and auxiliary ports\u003c\/li\u003e\n\u003cli\u003eSeparate 8 x 50mm finderscope in spring-loaded quick release bracket\u003c\/li\u003e\n\u003cli\u003e1.25\" star diagonal\u003c\/li\u003e\n\u003cli\u003e1.25\" 40mm Plössl eyepiece (70x)\u003c\/li\u003e\n\u003cli\u003e12V DC power cord\u003c\/li\u003e\n\u003cli\u003eDust covers.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":40221658579017,"sku":"CPC11X","price":4299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/8283_1.jpg?v=1662967542"},{"product_id":"nexstar-8-se-8-go-to-sct","title":"Celestron NexStar 8 SE 8\" Go-To SCT  11069","description":"\u003cp\u003eThe NexStar 8 SE gives you 21st century technology for less than the price of a 1984-model scope.

But it had Celestron's superb optics. Many people still fondly recall their original orange tube Celestron C8 as being the best telescope they ever had.\u003c\/p\u003e\n\u003cp\u003eWell, Celestron's optical quality is still there. And Celestron's NexStar 8 SE has brought back the orange and black C8 for those who love the look of the original, but with a slew of modern updates. All of it a a price less than that of the 1984 scope!\u003c\/p\u003e\n\u003cp\u003eIts optics are enhanced by the most advanced optical coatings available from Celestron - new Starbright XLT multicoatings. Across the full photo\/visual spectrum from 400nm to 750nm, independent laboratory tests show the new Starbright XLT coatings are 16% brighter than even Celestron's legendary original Starbright multicoatings - long the industry standard.\u003c\/p\u003e\n\u003cp\u003eThe Celestron NexStar 8 SE comes with a red dot finder, tripod, 25mm Plössl eyepiece, flashlight battery-operated dual-axis motor drives, and a go-to computerized hand control that will find over 40,000 stars and deep space objects for you automatically.\u003c\/p\u003e\n\u003cp\u003eNew SkyAlign technology makes it easy to line up this Celestron telescope on the sky so it can find celestial objects for you. You don't have to level the scope or point it north, or know which stars are which. Simply point the scope at any three bright stars, or at two bright stars and a planet or the Moon (you don't even have to know which stars and planet you're looking at). The telescope will then know how the sky is laid out that night and will be ready to find and track over 45,000 objects for you at your command.\u003c\/p\u003e\n\u003cp\u003eThe Celestron NexStar 8 SE has all the features and optical performance you need to keep you happily observing for years to come - and a classic color scheme that will draw admiring glances wherever you take your scope.

Starbright XLT multicoatings give you higher light transmission for brighter deep space images and shorter exposure times during photography. They also visibly increase the contrast on subtle lunar, planetary, and nebula details when compared with a scope with standard coatings or multicoatings.

Saturn and its system of faint moons proved to be a good test of the C6's light grasp, resolution, and image contrast. With an 8mm eyepiece, the planet's crisp globe revealed delicate cloud banding rendered in faithful color, while the Cassini Division in the rings was obvious for its entire visible extent. Despite the moonlight and heavy local light pollution, 10th-magnitude Tethys, just 7 arcseconds from Saturn's northern limb, was easily seen with direct vision. Intra- and extra-focal image of stars revealed the C6 to smooth and very well corrected optics.

A compartment in the drive base accepts eight user-supplied AA batteries for powering the scope in the field. The Celestron Power Tank Lithium (#PTL12V) is a highly recommended optional 7 amp-hour capacity multi-purpose rechargeable 12V DC battery that can provide several nights worth of observing from a single charge. To conserve battery life, an optional 2.5 Amp AC adapter (#2338N) is available to operate the scope from household current during backyard use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComputer control:\u003c\/strong\u003e The supplied NexStar computer hand control has a 45,000+ object database of stars and objects that it can locate and track for you. The database includes the complete RNGC, Messier, Caldwell, IC, and Abell catalogs; selected SAO stars (including the best variable stars and multiple star systems); the planets; the Moon; and more. You can also store and edit the right ascension and declination coordinates of 400 objects of your own choosing, such as favorite deep space objects or the comet and asteroid coordinates published monthly in Astronomy and Sky \u0026amp; Telescope magazines.\u003cbr\u003e\u003cbr\u003eYou have several ways to have the NexStar computer find celestial objects for you. The most popular and easiest to use is Celestron's exclusive SkyAlign no-guesswork technology. After turning on the scope, simply enter the date and time and your location, then point the scope at any three bright stars, or at two bright stars and a planet or the Moon (you don't even have to know which stars and planet you're looking at, and you don't have to know and locate specific stars as you do with other alignment programs). The NexStar computer will use the stars you've pointed at to model the sky overhead. Once it knows what the sky looks like, it's ready to find and track over 45,000 objects for you at your command.\u003c\/p\u003e\n\u003cp\u003eThe computer hand control includes a built-in RS-232 communication port allowing you to use a CCD autoguider for deep space photography. It also lets you use popular astronomy software to control the NexStar from a lap top or personal computer for remote control point-and-click slewing. The hand control software can now be flash-upgraded from the Celestron website. You can always have the most up-to-date control program, database, and software features simply by downloading the new programs as they are posted.\u003c\/p\u003e\n\u003cp\u003eThe scope can be operated with its ergonomically designed hand control conveniently docked in its fork arm storage compartment. You can also remove the control and its coiled connecting cord from the fork arm for hand-held use. There's no need to worry about wrapping the cord around the mount as you walk around the scope to observe different parts of the sky. The hand control plugs into the fork arm rather than the base, so it always moves with the scope.\u003cbr\u003e\u003cbr\u003eAll of the database and scope operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. There are 19 fiber optic backlit LED buttons to make it easy for you to control the computer without affecting your dark-adapted vision. If you are new to astronomy, you may wish to start by using the computer's built-in Sky Tour feature. This program commands the NexStar 6 SE to find the most interesting objects in the sky and automatically slews to them one at a time for you to observe at your leisure.\u003c\/p\u003e\n\u003cp\u003eNo matter what level of experience you start from, however, the NexStar 6 SE will unfold all the wonders of the Universe for you, your family, and your friends.

Adjusting for inflation, that equals greater than $3100 in todays dollars! How times have changed. This 5\" Celestron NexStar 5 SE has all those features - and more – for less than 1982's C5 cost!\u003c\/p\u003e\n\u003cp\u003eThe NexStar 5 SE is a great alternative to costly competitive 5\" Maksutovs. While it has the same light-gathering capacity as a 5\" Mak, its faster focal ratio means a wider field and brighter images with any given eyepiece than a Mak. And it's priced far less than competitive 5\" Maks that don't have the clear optical advantage of Celestron's state-of-the-art XLT multicoatings. Across the full photo\/visual spectrum from 400nm to 750nm, independent laboratory tests show the new Starbright XLT coatings are 16% brighter than even Celestron's legendary original Starbright multicoatings - long the industry standard.\u003c\/p\u003e\n\u003cp\u003eThe Celestron NexStar 5 SE comes with a red dot finder, tripod, 25mm Plössl eyepiece, flashlight battery-operated dual-axis motor drives, and a go-to computerized hand control that will find over 45,000 stars and deep space objects for you automatically.\u003c\/p\u003e\n\u003cp\u003eNew SkyAlign technology makes it easy to line up this Celestron telescope on the sky so it can find celestial objects for you. You don't have to level the scope or point it north, or know which stars are which. Simply point the scope at any three bright stars, or at two bright stars and a planet or the Moon (you don't even have to know which stars and planet you're looking at). The telescope will then know how the sky is laid out that night and will be ready to find and track nearly 40,000 objects for you at your command.\u003c\/p\u003e\n\u003cp\u003eThe Celestron NexStar 5 SE has all the features and optical performance you need to keep you happily observing for years to come - and a classic color scheme that will draw admiring glances wherever you take your scope.

Starbright XLT multicoatings give you higher light transmission for brighter deep space images and shorter exposure times during photography. They also visibly increase the contrast on subtle lunar, planetary, and nebula details when compared with a scope with standard coatings or multicoatings.

Built-in friction clutches in altitude and azimuth keep the optical tube fixed in place when eyepieces or accessory loads are changed. No mechanical locking levers or knobs are required.\u003cbr\u003e\u003cbr\u003eThe 11 lb. mount includes slewing\/tracking motors in both altitude and azimuth. There are nine user-selectable slewing\/centering\/guiding speeds - 6°\/second; 3°\/second; 1.5°\/second; and 128, 64, 16, 8, 2, and 1x sidereal. There are also three selectable drive rates - sidereal, solar, and lunar. The drives normally operate in the altazimuth mode (right\/left up\/down) to locate and track objects for visual use and casual solar system photography. If long exposure deep space photography is planned, the tripod includes a built-in wedge that quickly converts the scope to equatorial operation.\u003cbr\u003e\u003cbr\u003eA compartment in the drive base accepts eight user-supplied AA batteries for powering the scope in the field. The Celestron Power Tank Lithium (#PTL12V) is a highly recommended optional 7 amp-hour capacity multi-purpose rechargeable 12V DC battery that can provide several nights worth of observing from a single charge. To conserve battery life, an optional 2.5 Amp AC adapter (#2338N) is available to operate the scope from household current during backyard use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComputer control:\u003c\/strong\u003e The supplied NexStar computer hand control has a nearly 40,000 object database of stars and objects that it can locate and track for you. The database includes the complete RNGC, Messier, and Caldwell catalogs; selected SAO stars (including the best variable stars and multiple star systems); the planets; the Moon; and more. You can also store and edit the right ascension and declination coordinates of 200 objects of your own choosing, such as favorite deep space objects or the comet and asteroid coordinates published monthly in \u003cem\u003eAstronomy\u003c\/em\u003e and \u003cem\u003eSky \u0026amp; Telescope\u003c\/em\u003e magazines.\u003cbr\u003e\u003cbr\u003eYou have several ways to have the NexStar computer find celestial objects for you. The most popular and easiest to use is Celestron's exclusive SkyAlign no-guesswork technology. After turning on the scope, simply enter the date and time and your location, then point the scope at any three bright stars, or at two bright stars and a planet or the Moon (you don't even have to know which stars and planet you're looking at, and you don't have to know and locate specific stars as you do with other alignment programs). The NexStar computer will use the stars you've pointed at to model the sky overhead. Once it knows what the sky looks like, it's ready to find and track nearly 40,000 objects for you at your command.\u003cbr\u003e\u003cbr\u003eThe computer hand control includes a built-in RS-232 communication port allowing you to use a CCD autoguider for deep space photography. It also lets you use popular astronomy software to control the NexStar from a lap top or personal computer for remote control point-and-click slewing. The hand control software can now be flash-upgraded from the Celestron website. You can always have the most up-to-date control program, database, and software features simply by downloading the new programs as they are posted.\u003c\/p\u003e\n\u003cp\u003eThe scope can be operated with its ergonomically designed hand control conveniently docked in its fork arm storage compartment. You can also remove the control and its coiled connecting cord from the fork arm for hand-held use. There's no need to worry about wrapping the cord around the mount as you walk around the scope to observe different parts of the sky. The hand control plugs into the fork arm rather than the base, so it always moves with the scope.\u003cbr\u003e\u003cbr\u003eThe computer includes a camera control software program and a camera shutter cable. These let you remotely take a series of timed exposures using your digital SLR camera (connected to the scope by an appropriate camera adapter). This can be very useful during lunar or solar eclipses and during occultation events, since you won't have to miss any of the sights while worrying about the operation of your camera.\u003cbr\u003e\u003cbr\u003eAll of the database and scope operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. There are 19 fiber optic backlit LED buttons to make it easy for you to control the computer without affecting your dark-adapted vision. If you are new to astronomy, you may wish to start by using the computer's built-in Sky Tour feature. This program commands the NexStar 5 SE to find the most interesting objects in the sky and automatically slews to them one at a time for you to observe at your leisure.\u003c\/p\u003e\n\u003cp\u003eNo matter what level of experience you start from, however, the NexStar 5 SE will unfold all the wonders of the Universe for you, your family, and your friends.

The most popular and easiest to use is Celestron's exclusive SkyAlign no-guesswork technology. After turning on the scope, simply enter the date and time and your location, then point the scope at any three bright stars, or at two bright stars and a planet or the Moon (you don't even have to know which stars and planet you're looking at, and you don't have to know and locate specific stars as you do with other alignment programs). The NexStar computer will use the stars you've pointed at to model the sky overhead. Once it knows what the sky looks like, it's ready to find and track nearly 40,000 objects for you at your command. Not all of the objects may be easily visible, however, due to the scope's limited aperture.\u003c\/p\u003e\n\u003cp\u003eThe computer hand control includes a built-in RS-232 communication port allowing you to use a CCD autoguider for deep space photography. It also lets you use popular astronomy software to control the NexStar from a lap top or personal computer for remote control point-and-click slewing. The hand control software can now be flash-upgraded from the Celestron website. You can always have the most up-to-date control program, database, and software features simply by downloading the new programs as they are posted.\u003c\/p\u003e\n\u003cp\u003eThe scope can be operated with its ergonomically designed hand control conveniently docked in its fork arm storage compartment. You can also remove the control and its coiled connecting cord from the fork arm for hand-held use. There's no need to worry about wrapping the cord around the mount as you walk around the scope to observe different parts of the sky. The hand control plugs into the fork arm rather than the base, so it always moves with the scope.\u003cbr\u003e\u003cbr\u003eThe computer includes a camera control software program and a camera shutter cable. These let you remotely take a series of timed exposures using your digital SLR camera (connected to the scope by an appropriate camera adapter). This can be very useful during lunar or solar eclipses and during occultation events, since you won't have to miss any of the sights while worrying about the operation of your camera.\u003cbr\u003e\u003cbr\u003eAll of the database and scope operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. There are 19 fiber optic backlit LED buttons to make it easy for you to control the computer without affecting your dark-adapted vision. If you are new to astronomy, you may wish to start by using the computer's built-in Sky Tour feature. This program commands the NexStar 4 SE to find the most interesting objects in the sky and automatically slews to them one at a time for you to observe at your leisure.\u003cbr\u003e\u003cbr\u003eNo matter what level of experience you start from, however, the NexStar 4 SE will unfold many of the wonders of the Universe for you, your family, and your friends.

Featuring a new enlarged 2.4\" focuser and redesigned optics, this new TeleVue NP101is (Imaging System) improves and extends the photographic capability of the original NP101.\u003c\/p\u003e\n\u003cp\u003eThe new TeleVue NP101is sets new optical and mechanical quality standards in a moderately small and highly portable apochromatic refractor for the serious observer and astrophotographer. TeleVue first reinterpreted the incredible design flexibility of the time-proven Petzval portrait lens into an astronomical objective over 20 years ago. They've been refining the design ever since. Nagler-Petzval optics permit the optical designer greater freedom to simultaneously correct for coma, astigmatism, field curvature, secondary spectrum, spherical aberration, and spherochromatism than any other commercial optical design.\u003c\/p\u003e\n\u003cp\u003eThis newest 4\" four-element air-spaced Nagler-Petzval system has a 101mm aperture ED doublet at the front of the scope, with a second field-flattening\/aberration-correcting ED doublet at the rear. This combination of materials and design gives the TeleVue NP101is diffraction-limited apochromatic (spurious color-free) performance across the entire visual spectrum. In addition to exceptional visual performance, both inside the solar system and beyond, it has been optimized for deep space imaging, particularly with CCD cameras having large format detector chips with diagonals up to 50mm across. Every optical and mechanical element has been optimized to work as a single integrated unit, with new features to make imaging easier and more flexible.\u003c\/p\u003e\n\u003cp\u003eFor visual use, the scope's 540mm focal length is long enough, using a 1.25\" TeleVue 2.5mm Nagler eyepiece, to provide 216x for high magnification observations of the Moon, planets, and binary stars; yet it will also produce a huge 4.1° field at 15x, using a 2\" TeleVue 35mm Panoptic eyepiece for wide field observing.\u003c\/p\u003e\n\u003cp\u003eIts image quality, easy set-up, and airline portability make it a scope you will use often. Manufacturing advances in lens finishing, including interferometric monitoring of all surfaces, and TeleVue's stringent made-in-the-USA telescope assembly and quality control, insure uniformly excellent results with every telescope, and a level of manufacturer-direct service that's all too rare.\u003c\/p\u003e\n\u003cp\u003eWhether you are interested in terrestrial nature studies, astronomical rich-field or planetary observing, or photography of the earth and skies, just put in an optional star diagonal and eyepiece or attach a camera and the TeleVue NP101is will satisfy your observing desires right out of its case.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Telescope's Optical and Mechanical Systems . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNagler-Petzval apochromatic refractor optics:\u003c\/strong\u003e 4\" (101mm) aperture, 540mm focal length, f\/5.4 apochromatic four-element air-spaced optical system.

The 50x erect image eyepiece lets you use the 114EQ terrestrially, as its images are not upside-down as they are with most reflectors. Both eyepieces are a higher quality optical design than you'll find in most other telescopes in this price range. They have antireflection coatings on their lens surfaces for sharp images and very good contrast. Instead of providing low quality eyepieces that give unrealistically high (and generally unusable) 200-300x magnifications, Celestron has chosen to provide higher quality eyepieces with sensible powers you can use and enjoy every time you take your AstroMaster out to observe.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinderscope: \u003c\/strong\u003eA non-magnifying red dot finder is permanently attached to the side of the optical tube.

By aligning the mount on the north celestial pole, you only need to turn one slow motion control knob to follow planets and stars as they travel across the sky. Two counterweights on the opposite side of the mount from the telescope balance the weight of the optical tube and makes it easy to move the scope effortlessly from one part of the sky to another. No tools are required to adjust the position of the counterweights to quickly and precisely balance the optical tube.

The second controls the scope's motion in declination (the north\/south direction in the sky). Turning this knob enables you to correct for any north\/south drift a celestial object may take as it drifts across the sky, due to an improper alignment of the scope on the north celestial pole when you first set it up. The two controls combine to give you complete access to any part of the sky. They give you the ability to star hop from a known object to any other object by using a star chart. They let you center objects in the field of view, and track them effortlessly with only an occasional quick turn of the r. a. knob.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTripod: \u003c\/strong\u003eThe very rigid tripod has 1.25\" diameter stainless steel legs for vibration-free observing.

This sensibly-priced refractor optical system is a good way to begin your journey into the night sky, as well as exploring nature during the day. It provides you with detailed high-contrast views of the Moon and planets in the heavens, as well as sharp views of birds and animals across a lake or across the way.\u003c\/p\u003e\n\u003cp\u003eThe construction of the optical system is first rate, as the AstroMaster has all-glass optical components, with high transmission optical coatings for enhanced image brightness and clarity. The mount has a convenient pan handle, like the control handle on a camera tripod, for guiding the scope around the skies or the landscape. A built-in clutch makes operating the well-balanced scope with the pan handle smooth and easy. The scope assembles in only a minute or two, with no tools required.\u003c\/p\u003e\n\u003cp\u003eOnce you have scanned your way through the solar system and the Milky Way, you can use the AstroMaster to look at things closer to home.

It provides erect mirror image views (objects are reversed left for right). This is not a problem when observing the stars and planets, but may be disconcerting during terrestrial observing, as printing (license plates, the names on boats, etc.) will be backwards. For most nature studies this isn't a problem, though, because a duck still looks like a duck whether he's facing left or right. An optional #6329 45° viewing angle image-erecting diagonal is available if right-reading images are essential.

This lets you control how smoothly the mount moves as you move the tube left or right to follow objects moving across the sky or on the land. A simple twist on the pan handle locks the scope in place up and down, as well as letting you adjust the drag on the scope to set the travel smoothness when adjusting its position vertically. The optical tube is well balanced, but keeping your hand on the pan handle at all times when the clutches are unlocked would be a sensible safety precaution.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTripod:\u003c\/strong\u003e The lightweight pre-assembled tripod has 1.5\" diameter stainless steel legs to provide a rigid and stable observing platform.

Using optional eyepieces and\/or a Barlow to boost the magnification, you can see subtle solar system details that are virtually invisible in smaller aperture scopes. You can study lunar craters, rilles, mountain ranges, and low contrast lunar ray detail. With reasonable seeing conditions, detail in Jupiter's cloud belts and the Great Red Spot (actually closer in color to the Faint Pink Spot at this point in time) are visible, as are dusky markings on the face of Saturn and Cassini's division in Saturn's brilliant rings. Chromatic aberration (a faint halo of spurious violet light around very bright objects, such as the planets) is present, as it is in all achromatic refractor telescopes, but is generally unobjectionable and is not a problem on the faint objects outside the solar system. Using the lens cap\/aperture stop mentioned above will reduce its visibility. The use of an optional aberration-reducing minus violet filter will also help eliminate the spurious color (which many people find unobjectionable in any case).\u003c\/p\u003e\n\u003cp\u003eOptically and mechanically refined, and very reasonable in cost for a big 4.7\" aperture refractor, this Celestron Omni XLT 120 has enough optical performance to keep you busy for the rest of your life.\u003c\/p\u003e\n\u003ch2\u003eTech Details: \u003c\/h2\u003e\n\u003ctable class=\"table\" id=\"product-attribute-specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eAperture\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e4.7\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e1000mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/8.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e21 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHighest Useful Magnification\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e250x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMotorized Controls\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eOptional Motor Drive Is Available\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e46 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e0.97 arc seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied Eyepiece\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e25mm 1.25\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTelescope Type\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eRefractor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eView Finder\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e6x30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVisual Limiting Magnitude\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e12.9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e2 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eSupplied Accessories: \u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFully Starbright XLT multicoated 120mm aperture 1000mm focal length f\/8.3 achromatic optics\u003c\/li\u003e\n\u003cli\u003eCG-4 German equatorial mount with setting circles, manual slow motion controls, and adjustable height steel leg tripod with combined spreader bar\/accessory tray\u003c\/li\u003e\n\u003cli\u003e6 x 30mm straight-through finder\u003c\/li\u003e\n\u003cli\u003e2\" rack and pinion focuser with 1.25\" eyepiece adapter\u003c\/li\u003e\n\u003cli\u003e1.25\" prism-type 90° star diagonal\u003c\/li\u003e\n\u003cli\u003e1.25\" 25mm eyepiece (40x)\u003c\/li\u003e\n\u003cli\u003eDewcap\u003c\/li\u003e\n\u003cli\u003eDust covers\u003c\/li\u003e\n\u003cli\u003eTwo-year warranty.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":40221660446793,"sku":"C120XLT","price":849.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/13749.jpg?v=1662967612"},{"product_id":"6-omni-xlt-150-equatorial-f-5-reflector-with-starbright-xlt-multicoated-mirrors","title":"Celestron 6\" Omni XLT 150 Equatorial f\/5 Reflector with Starbright XLT Multicoated Mirrors","description":"\u003cp\u003eThis Celestron Omni XLT 150 puts a big 6\" aperture fast focal ratio reflector, with Starbright XLT multicoated mirrors for maximum light transmission, on a solid German equatorial mount.

The Celestron Omni XLT 150 works well visually from many city and suburban sites, as its f\/5 focal ratio keeps moderately light-polluted sky backgrounds reasonably dark to avoid washing out faint nebula detail. As with any scope, however, transporting the Celestron Omni XLT 150 to a dark sky observing site will markedly improve its performance on broad, faint deep sky objects at low powers. \u003cbr\u003eIn addition, the 750mm focal length of this Celestron makes it easy to achieve the high powers needed for detailed lunar and planetary observing.

The optical tube is aluminum, to allow the mirrors to cool to ambient temperature more quickly. Also, the lower end of the tube is sealed to reduce image-degrading thermal currents within the optical tube. These features extend your undisturbed viewing time by minimizing the time you have to wait for the images to stabilize after you take your scope outside in the cold air of late fall or winter. The scope's tube end rings are sturdy die cast aluminum, to protect the tube during transport and provide exceptionally rigid support for the optics. The mirror cell's six-screw push\/pull locking collimation system keeps the primary mirror aligned far longer than conventional mirror cells - so you spend more time observing, and less time adjusting the optics. The lightweight optical tube rotates in its felt-lined die cast cradle rings to bring the focuser and finder to the most comfortable viewing position. The mounting rings even include a built-in piggyback mount for wide field astrophotography (using an optional motor drive). The 27\" long aluminum optical tube weighs only 12 lbs., making it easy to transport and assemble in the field.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStarbright XLT multicoated mirrors:\u003c\/strong\u003e Fully coated with multiple vacuum-deposited layers of high reflectivity aluminum.

It gives you correctly oriented images and more comfortable extended terrestrial observing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTwo eyepieces:\u003c\/strong\u003e You get a high power 1.25\" 10mm (100x) eyepiece and a low power erect image 1.25\" 20mm (50x) with a 1° field of view (twice the diameter of the full Moon). The 50x erect image eyepiece lets you use the 90EQ terrestrially, as its images are not reversed as they are with most refractors. However, the equatorial mount will make it difficult to center and track objects on the ground. The erect image eyepiece will probably serve you better for lunar observing, as it will show you a familiar image of the Moon, oriented as you see it with your unaided eyes or binoculars. Both eyepieces are of a higher quality optical design than you'll find in most other telescopes in this price range. They have antireflection coatings on their lens surfaces for sharp images and very good contrast. Instead of providing low quality eyepieces that give unrealistically high (and generally unusable) 200-300x magnifications as most economy telescope manufacturers do, Celestron has chosen to provide higher quality eyepieces with sensible powers you can use and enjoy every time you take your AstroMaster 90EQ out to observe.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRed dot finder:\u003c\/strong\u003e A straight-through red dot illuminated finder allows easy non-magnified views of the sky and ground, with a projected red dot of light showing exactly where the scope is pointed at all times.

By aligning the mount on the north celestial pole, you only need to turn one slow motion control knob to follow planets and stars as they travel across the sky. An economical optional #MDASTRO battery-operated right ascension motor drive takes the slow motion control out of your hand and makes following the stars a no-hands operation. Two counterweights on the opposite side of the mount from the telescope tube balance the weight of the optical tube and make it easy to move the scope effortlessly from one part of the sky to another. No tools are required to adjust the position of the counterweights to quickly and precisely balance the optical tube.

These allow you to align the scope on the approximate position of an object in the sky by using its r. a. and dec coordinates from a star chart or atlas - before you search for it in the finderscope and eyepiece.

Turning this knob enables you to follow the motion of celestial objects as they travel from east to west across the sky. The second controls the scope's motion in declination (the north\/south direction in the sky). Turning this knob enables you to correct for any north\/south drift a celestial object may take as it moves across the sky, due to an improper alignment of the scope on the north celestial pole when you first set it up. The two controls combine to give you complete access to any part of the sky. They give you the ability to star hop from a known object to any other object by using a star chart. They let you center objects in the field of view, then track them effortlessly with only an occasional quick turn of the r. a. knob.

They also give you higher light transmission for brighter deep space images and shorter exposure times during CCD and 35mm photography. Across the total visual\/photographic spectrum from 400nm to 750nm, independent laboratory tests show the new Starbright XLT coatings are 16% brighter overall than even the original industry-standard Starbright multicoatings.\u003c\/p\u003e\n\u003cp\u003eThe optical tube comes with a 6 x 30mm straight-through achromatic finderscope and mounting bracket.

It includes a right ascension motor drive for no-hands tracking of celestial objects.

At only 25 lbs., it's lightweight and compact enough to fit in virtually any storage space, but it's optically big enough to keep an observer happy for years. At its very affordable price, the Astromaster 130 is a bargain indeed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Telescope's Optical System . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReflector optical tube:\u003c\/strong\u003e 130mm (5.1\") aperture 650mm focal length f\/5 focal ratio Newtonian reflector. All-glass mirrors, coated with highly reflective aluminum and overcoated with quartz for long life. There are no plastic optical components. The 24\" long aluminum optical tube has protective tube end rings. The reflector design of the scope is totally free of the purple haze of spurious color visible around the Moon and planets in lesser refractor scopes. Images are sharp and clear. You can even collimate (align) both mirrors for the sharpest images. This will have to be done only rarely, thanks to the special push\/pull design of the cell holding the primary mirror.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRack and pinion focuser:\u003c\/strong\u003e The 1.25\" focuser has dual focusing knobs for precise image control with either hand.

The 32.5x erect image eyepiece lets you use the 130EQ terrestrially, as its images are not upside down as they are with most reflectors. However, the equatorial mount will make it difficult to center and track objects on the ground. The erect image eyepiece will probably serve you better for lunar observing, as it will show you a familiar image of the Moon, oriented as you see it with your unaided eyes or binoculars. Both eyepieces are of a higher quality optical design than you'll find in most other telescopes in this price range. They have antireflection coatings on their lens surfaces for sharp images and very good contrast. Instead of providing low quality eyepieces that give unrealistically high (and generally unusable) 200-300x magnifications as most economy telescope manufacturers do, Celestron has chosen to provide higher quality eyepieces with sensible powers you can use and enjoy every time you take your AstroMaster 130 out to observe.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFinderscope:\u003c\/strong\u003e A non-magnifying red dot finder is permanently attached to the side of the optical tube. The battery-operated red dot finder seems to project a dot of red light on the sky or on the daytime landscape exactly where the telescope is pointed. The red dot will help you center distant objects in the telescope so you don't have to search for them using the narrow eyepiece field of view. Collimating knobs on the finder let you line up its red dot precisely with the main telescope optics to make centering distant objects easy and painless.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Telescope's Mount . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEquatorial mount:\u003c\/strong\u003e The scope's sturdy CG-3 equatorial mount is designed for astronomical observing. By aligning the mount on the north celestial pole, you only need to turn one slow motion control knob to follow planets and stars as they travel across the sky (or let the supplied battery-operated motor drive do it for you automatically). Two counterweights on the opposite side of the mount from the telescope tube balance the weight of the optical tube and make it easy to move the scope effortlessly from one part of the sky to another. No tools are required to adjust the position of the counterweights to quickly and precisely balance the optical tube. A micrometer control lets you adjust the altitude of the scope mount to match your latitude for fast alignment on the north celestial pole with no tools required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMotor drive:\u003c\/strong\u003e A battery-operated motor drive makes following the stars a no-hands operation. The drive is a single axis right ascension drive motor only. It does not have drive corrector functions for long exposure astrophotography. The drive has a variable speed control to match the differing speeds at which the Moon, planets, Sun, and stars move across the sky. It also has switch-controlled northern\/southern hemisphere operation. The drive runs for up to 40 hours from one 9 volt transistor radio battery (supplied), depending on the air temperature (battery life is shorter when the temperatures are colder). Your telescope can be manually moved to any part of the sky while the drive is functioning by releasing the right ascension and declination locks and pushing the telescope tube in the desired direction. However, the drive does not have a built-in clutch, so the thumbscrew attaching the drive to the telescope must be loosened if very precise centering and positioning is desired using the manual slow motion controls.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSplit Ring Optical Tube mount:\u003c\/strong\u003e The optical tube mounts in hinged split rings that are attached to a dovetail bar that fits into a quick-release dovetail groove on the top of the mount.

These allow you to align the scope on the approximate position of an object in the sky by using its r. a. and dec coordinates from a star chart or atlas - before you search for it in the finderscope and eyepiece. Setting circles can reduce the time it takes for you to find the fainter and more difficult deep space objects.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eManual slow motion controls:\u003c\/strong\u003e There are two slow motion control knobs conveniently positioned on the mount so they are easy to reach while observing. One controls the scope's motion in right ascension (the east\/west direction in the sky). Turning this knob enables you to follow the motion of celestial objects as they travel from east to west across the sky if you are not using the supplied battery-operated motor drive. The second controls the scope's motion in declination (the north\/south direction in the sky). Turning this knob enables you to correct for any north\/south drift a celestial object may take as it moves across the sky, due to an improper alignment of the scope on the north celestial pole when you first set it up. The two controls combine to give you complete access to any part of the sky. They give you the ability to star hop from a known object to any other object by using a star chart. They let you center objects in the field of view, then track them effortlessly with only an occasional quick turn of the r. a. knob. As mentioned above, a motor drive is also provided for hands-free tracking of celestial objects.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTripod:\u003c\/strong\u003e The lightweight pre-assembled tripod has 1.25\" diameter stainless steel legs to provide a rigid and stable observing platform.

This modestly-priced imaging accessory essentially eliminates the residual field curvature inherent in all reflector telescope designs, so that the coma-free star images remain point-like all across the field. An optical analysis and ray tracing of the field flattener was done in ZEMAX and applied to the R-Cs by Roger Ceragioli, the noted optical designer who did the final optimization of the Astro-Tech Ritchey-Chrétien optics. Here is what he had to say about the #AT2FF, \"My conclusion, which seems supported by what users are saying, is that you don't need any other field flattener. This one performs well over a 40mm image circle in all three small RCs (6\", 8\", and 10\").\"\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: medium;\"\u003e\u003cstrong\u003eTwo compression ring accessory holders:\u003c\/strong\u003e The focuser drawtube ends in a 2\" accessory holder that uses a non-marring soft brass compression ring to hold 2\" imaging accessories in place.

But Takahashi goes a step further to perfect your observing and imaging experience. There is a second widely air-spaced ED doublet buried deep within the telescope body. This second doublet optimizes the optical wavefront from the objective lens to eliminate any residual astigmatism. It also acts as a field flattener for wide field astrophotography.

Dobsonian, you don't have to worry about lifting the scope's diagonal mirror cage and trying to bolt it to three swaying truss tube in the dark as you do with other truss-tube Dobs. Sky-Watcher's revolutionary telescoping truss-tube system attaches the top of the truss tubes permanently to the diagonal mirror cage, with the bottom of the tubes sliding into three die-cast housings on the scope's primary mirror tub. This unique system allows the optical tube's diagonal mirror cage and three attached truss tubes to slide down onto the primary mirror tub to form one compact 32.5\" long assembly. The cage and tub can then be locked together, using no-tool handles built into the primary mirror tub, and lifted out of the scope's altazimuth rocker base for easy and secure telescope transport.\u003c\/p\u003e\n\u003cp\u003eAssembling the Sky-Watcher Dob for use involves simply unlocking the diagonal mirror cage and raising the cage until spring-loaded catches on the truss tubes snap into place in the primary mirror tub. This holds the cage at its fully-raised position while you tighten the no-tool handles at the base of the truss tubes to lock the diagonal mirror cage securely in position for observing.\u003c\/p\u003e\n\u003cp\u003eFor binoviewing without unwanted extra magnification, a second set of indents on the truss tubes allows the diagonal mirror cage to be lowered to a preset locking position on the truss poles. This lets you to use a binoviewer without needing a corrector or Barlow lens in the binoviewer to reach focus.\u003c\/p\u003e\n\u003cp\u003eThe complete Sky-Watcher telescoping truss optical tube assembly - diagonal mirror cage, integral truss tubes, and primary mirror tub - weighs only 24.2 pounds (11 kg). The altazimuth rocker box base it sits in weighs only 26 pounds (11.8 kg). Total weight is a light 50.2 pounds. When aimed at the zenith, the eyepiece is 45.5\" above ground level.\u003c\/p\u003e\n\u003cp\u003eThe Sky-Watcher easily collapses in minutes into two small and light components that fit into a car trunk or into the back seat of a compact car. Competitive truss-tube Dobs break down into four or more components - diagonal mirror cage, primary mirror tub, altazimuth rocker box base, and truss tubes (as many as six to be carried separately or packed into an optional carrying bag). It's easy to see how the two-part Sky-Watcher has a definite convenience advantage over the four or more parts of a conventional truss-tube Dob. And, unlike bulky competitive solid-tube Sonotube or metal tube Dobs with an unwieldy 48\" or 50\" long optical tube, you don't need a big car to transport this 8\" Sky-Watcher.\u003c\/p\u003e\n\u003cp\u003eAssembly and disassembly take only about 5-10 minutes, with no tools needed. After you set up, particularly after traveling over bumpy roads to a dark sky site, take a few moments to check the collimation of the optics to assure peak performance and you are ready for an evening of fascinating viewing at your favorite dark sky location. The 8\" Sky-Watcher telescoping truss-tube Dobsonian is designed for visual observing only - to show you as much of the night skies as possible, and do it as conveniently and inexpensively as possible. Photography is not possible with a Dob.\u003c\/p\u003e\n\u003cp\u003eBecause of its compact component size, light individual component weights, and limited number of components to put together (after all, there are only two!), the 8\" Sky-Watcher telescoping truss-tube Dob can be transported and set up easily by one individual. This innovation gives Sky-Watcher users a cost-effective 8\" telescope with unsurpassed compactness and transportability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Sky-Watcher Dob's Optical Tube Assembly . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNewtonian reflector optics:\u003c\/strong\u003e 8\" diameter parabolic primary mirror, with 1.85\" m.a. diagonal mirror.

The 25mm gives rich and expansive deep space views of star clouds, galaxies, and nebulas alike. The 10mm Plössl provides a stout 120x magnification with a 0.43° field of view, enough magnification to provide sharp close-up views of the Moon, planets, globular star clusters, and more.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOptical tube dimensions:\u003c\/strong\u003e Tube diameter (outside of one side bearing to the outside of the other bearing): 11.25\"; tube length collapsed: 33\"; tube length extended: 44\".\u003cbr\u003eThis Sky-Watcher Dob's Base Assembly . . .\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRocker box altazimuth base:\u003c\/strong\u003e The altazimuth rocker box that the mirror tub rides in is crafted of strong, lightweight, and water-resistant laminated particle board, as is the water-resistant ground board that the rocker box rides on. The base is shipped disassembled, but can be put together in about a half an hour using only a screwdriver and the supplied hardware. Teflon bearings in both altitude and azimuth provide smooth and effortless motion of the optical tube in all directions. At the same time, the Teflon provides the proper amount of stiction to assure backlash-free movement, without the inadvertent and uncontrolled motions sometimes caused by wind gusts pushing on mounts using azimuth roller-bearings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNavigation knobs:\u003c\/strong\u003e Two navigation knobs conveniently mounted on the diagonal mirror cage makes it easy to control the scope' motion in any direction.

In the constellation Sagittarius lie several of the sky's most prominent emission nebulas. The Lagoon Nebula (M8) is a rich aggregation of dust and gasses illuminated by its youthful central stars. This is an area of star formation, the universe giving birth. Located nearby is the smaller, but very beautiful, Trifid Nebula (M20). The magnificent Swan Nebula (M17) is also located in Sagittarius. The sky's most awesome globular star cluster, M13, a bee-hive of thousands of stars swarming about a central core, is located in the constellation Hercules. This is the brightest object of its kind and is always a treat to view. Globular clusters are no longer being formed in the Milky Way, so in M13 you are observing fossil light, a glimpse back in time. Under dark skies, the Orion Nebula (M42) becomes a glowing complex of filaments, filling the wide 1.08° field of the standard eyepiece. Messier, NGC, and IC objects show detail and structure never visible in the smaller telescopes that are more common in this price range.\u003c\/p\u003e\n\u003cp\u003eAs with any serious telescope, the performance of the 8\" Sky-Watcher telescoping truss-tube Dob on faint objects will be improved by a dark sky observing site. Heavily light-polluted city and suburban sites are not the best for observing very faint objects with any 8\" scope.\u003c\/p\u003e\n\u003cp\u003eWithin the solar system, given suitably good seeing, Encke's Division and other minor features in Saturn's rings occasionally become visible in the 8\" telescoping truss-tube, as does Saturn's faint crêpe ring.

Sky-Watcher's revolutionary telescoping truss-tube system attaches the top of the truss tubes permanently to the diagonal mirror cage, with the bottom of the tubes sliding into three die-cast housings on the scope's primary mirror tub.\u003c\/p\u003e\n\u003cp\u003eThis unique system allows the optical tube's diagonal mirror cage and three attached truss tubes to slide down onto the primary mirror tub to form one compact assembly. The cage and tub can then be locked together, using no-tool handles built into the primary mirror tub, and lifted out of the scope's altazimuth rocker base for easy and secure telescope transport.\u003c\/p\u003e\n\u003cp\u003eAssembling the Sky-Watcher Dob for use involves simply unlocking the diagonal mirror cage and raising the cage until spring-loaded catches on the truss tubes snap into place in the primary mirror tub. This holds the cage in its fully-raised position while you tighten the no-tool handles at the base of the truss tubes to lock the diagonal mirror cage securely in position for observing.\u003c\/p\u003e\n\u003cp\u003eFor binoviewing without unwanted extra magnification, a second set of indents on the truss tubes allows the diagonal mirror cage to be lowered to a preset locking position on the truss poles. This lets you to use a binoviewer without needing a corrector or Barlow lens in the binoviewer to reach focus.\u003c\/p\u003e\n\u003cp\u003eThe complete 10\" Sky-Watcher optical tube assembly - secondary mirror cage, truss tubes, and primary mirror tub - weighs only 33 pounds (15 kg). The altazimuth rocker box base it sits in weighs only 27.5 pounds (12.5 kg). Total weight is only 60.5 pounds, light for a full-sized 10\" telescope. When aimed at the zenith, the eyepiece is 48\" above ground level.\u003c\/p\u003e\n\u003cp\u003eThe Sky-Watcher easily collapses in minutes into two small and light components that fit into a car trunk or into the back seat of a compact car. Competitive truss-tube Dobs break down into four or more components - secondary mirror cage, primary mirror tub, altazimuth rocker box base, and truss tubes (as many as six to be carried separately or packed into an optional carrying bag).\u003c\/p\u003e\n\u003cp\u003eIt's easy to see how the two-part Sky-Watcher has a definite convenience advantage over the four or more parts of a conventional truss-tube Dob. And, unlike bulky competitive solid-tube Sonotube or metal tube Dobs with an unwieldy 48\" or 50\" long optical tube, you don't need a big car to transport this 10\" Sky-Watcher.\u003c\/p\u003e\n\u003cp\u003eAssembly and disassembly take only about 5-10 minutes, with no tools needed. After you set up, particularly after traveling over bumpy roads to a dark sky site, take a few moments to check the collimation of the optics to assure peak performance and you are ready for an evening of fascinating viewing at your favorite dark sky location. The 10\" Sky-Watcher telescoping truss-tube Dobsonian is designed for visual observing only - to show you as much of the night skies as possible, and do it as conveniently and inexpensively as possible. Photography is not possible with a Dob.\u003c\/p\u003e\n\u003cp\u003eBecause of its compact component size, light individual component weights, and limited number of components to put together (after all, there are only two!), the 10\" Sky-Watcher telescoping truss-tube Dob can be transported and set up easily by one individual. This innovation gives Sky-Watcher users a cost-effective 10\" telescope with unsurpassed compactness and transportability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Sky-Watcher Dob's Optical Tube Assembly . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNewtonian reflector optics:\u003c\/strong\u003e 10\" diameter parabolic primary mirror, with 2.3\" m.a. diagonal mirror.

Teflon bearings in both altitude and azimuth provide smooth and effortless motion of the optical tube in all directions.

With the 10\" Sky-Watcher, you have tremendous light gathering power to see faint and distant nebulas and galaxies - over 1300 times that of your unaided eye. Under dark skies, the Orion Nebula becomes a glowing and subtle complex of filaments, and color starts to become visible. The spiral structure of the Whirlpool Galaxy becomes apparent, as do dark dust lanes across the nucleus of the Andromeda Galaxy (although the full 3° width of the galaxy itself is far too large to fit into the field of view of any eyepiece generally usable with the scope). Globular clusters are frequently resolved to the very core. Messier, NGC, and IC objects show detail and structure never visible in smaller telescopes.\u003c\/p\u003e\n\u003cp\u003eMany challenging objects for an 8\" aperture scope now come into their own with the 10\" Sky-Watcher. The Crab planetary nebula (M1), a supernova remnant, requires a 10\" aperture to truly begin to appreciate its subtle, gaseous filamentary structures. M33, the low surface brightness face-on spiral galaxy in the constellation Triangulum, exhibits significantly more open arm structure than is visible in an 8\" scope. The Rosette Nebula in Monoceros begins to show the pattern of a blooming rose that gives the Rosette its name.\u003c\/p\u003e\n\u003cp\u003eThere is no question that the increased resolving power and 56% greater light-gathering power of a 10\" aperture is visually impressive when compared to an 8\" scope. Therefore, it is no wonder then that the 10\" aperture is overtaking the 8\" as the serious amateur astronomer's aperture of choice in a Dobsonian telescope. Sky-Watcher's compact, telescoping optical tube design makes the decision to step up in aperture to a 10\" scope even easier.\u003c\/p\u003e\n\u003cp\u003eAs with any large aperture telescope, the performance of the 10\" Sky-Watcher on faint objects will be markedly improved by a dark sky observing site. Light-polluted city and suburban sites are not recommended as the primary observing site with a 10\" scope.

Sky-Watcher's revolutionary telescoping truss-tube system attaches the top of the truss tubes permanently to the diagonal mirror cage, with the bottom of the tubes sliding into three die-cast housings on the scope's primary mirror tub.\u003c\/p\u003e\n\u003cp\u003eThis unique system allows the optical tube's diagonal mirror cage and three attached truss tubes to slide down onto the primary mirror tub and be locked in place to form one surprisingly compact assembly. By undoing the no-tool handles in the sides of the altazimuth base that hold the optical tube in the base, the cage and tub assembly can be lifted out of the scope's altazimuth rocker base as a single unit for easy and secure transport.\u003c\/p\u003e\n\u003cp\u003ePreparing the Sky-Watcher Dob for use involves simply unlocking the diagonal mirror cage and raising the cage until spring-loaded catches on the truss tubes snap into place in the primary mirror tub. This holds the cage in its fully-raised position while you tighten the no-tool locks at the base of the truss tubes to lock the diagonal mirror cage securely in position for observing.\u003c\/p\u003e\n\u003cp\u003eFor binoviewing without unwanted extra magnification, a second set of indents on the truss tubes allows the diagonal mirror cage to be lowered to a preset locking position on the truss poles. This lets you to use a binoviewer without needing a corrector or Barlow lens in the binoviewer to reach focus.\u003c\/p\u003e\n\u003cp\u003eWith a heaviest single component weight of only 46.2 pounds, the 12\" Sky-Watcher is a telescope that most reasonably-fit individuals should be able to set up and transport with little or no problems. The complete 12\" Sky-Watcher optical tube assembly - secondary mirror cage, truss tubes, and primary mirror tub - weighs only 46.2 pounds (21 kg). The altazimuth rocker box base it sits in weighs only 40.7 pounds (18.5 kg). Total weight is only 86.9 pounds, light for a full-sized 12\" telescope.\u003c\/p\u003e\n\u003cp\u003eThe Sky-Watcher easily collapses in minutes into two reasonably small and light components that fit into most car trunks or into the back seat of even a compact car. Competitive truss-tube Dobs break down into four or more components - a secondary mirror cage, primary mirror tub, altazimuth rocker box base, and truss tubes (as many as six to be carried separately or packed into an optional carrying bag). It's easy to see how the two-part Sky-Watcher has a definite convenience advantage over the four or more parts of a conventional truss-tube Dob. And, unlike bulky competitive solid-tube Sonotube or metal tube Dobs with an unwieldy 58\" or 60\" long optical tube, you don't need a big car to transport this 12\" Sky-Watcher.\u003c\/p\u003e\n\u003cp\u003eAssembly and disassembly take only 10 minutes or so, with no tools needed. After you set up, particularly after traveling over bumpy roads to a dark sky site, take a few moments to check the collimation of the optics to assure peak performance and you are ready for an evening of fascinating viewing at your favorite dark sky location. If observing from your back yard, you can leave scope assembled and simply roll it outside using a hand truck or a JMI Wheeley Bar.\u003c\/p\u003e\n\u003cp\u003eThe 14\" Sky-Watcher telescoping truss-tube Dobsonian is designed for visual observing only - to show you as much of the night skies as possible, and do it as conveniently and inexpensively as possible. Photography is not possible with a Dob.\u003c\/p\u003e\n\u003cp\u003eBecause of its reasonable component size, sensible individual component weights, and limited number of components to put together (after all, there are only two!), one fit individual can normally transport and set up the 12\" Sky-Watcher telescoping truss-tube Dob. Its innovative and unique telescoping design gives Sky-Watcher users a cost-effective 12\" telescope with unsurpassed compactness and transportability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Sky-Watcher Dob's Optical Tube Assembly . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNewtonian reflector optics:\u003c\/strong\u003e 12\" diameter parabolic primary mirror, with 2.75\" m.a. diagonal mirror.

The 25mm gives rich and expansive deep space views of star clouds, galaxies, and nebulas alike. The 10mm Plössl provides a stout 150x magnification with a 0.35° field of view, enough magnification to provide sharp close-up views of the Moon, planets, globular star clusters, multiple star systems, and more.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOptical Tube Dimensions:\u003c\/strong\u003e The telescoping 12\" optical tube measures 15.75\" (400mm) in diameter, 55\" (1397mm) long when extended, but a much more compact 36\" (914mm) in length when retracted.

You now have the tremendous light gathering power to see faint and distant nebulas and galaxies that you've always wanted - almost 1900 times that of your unaided eye. Many of the objects that are a challenge to even see in smaller aperture telescopes now show their essential structure. Objects just within the threshold of visibility with a 10\" aperture scope appear more prominent with the 12\" and may be worth observing for extended periods. Comet hunters will delight in the fainter magnitudes that are possible to see in the 12\" Sky-Watcher.\u003c\/p\u003e\n\u003cp\u003eHere at last is a telescope with the ability to visually tackle elusive deep-space gems like the Horsehead Nebula in Orion. In Perseus, the very faint 11th magnitude nebula M76 will be visible from a dark sky site, as will very faint planetary nebula M9 in Ursa Major. M61, the spiral galaxy in Virgo, reveals its spiral arms as you've always hoped to see them. The list goes on and on, and you will delight in planning your own nightly journeys of exploration.\u003c\/p\u003e\n\u003cp\u003eCompared to an 8\" or 10\" scope, the increased resolution and greater light-gathering power of this Sky-Watcher's 12\" aperture is beyond just being impressive. It lets its lucky owner resolve many, many objects that smaller telescopes simply don't have the horsepower to show satisfactorily because they can't pull in enough light. Compared to an 8\" scope, the 12\" Sky-Watcher has 50% greater resolution of small details and two and a quarter times the light-gathering to reveal fainter objects. Even compared to a 10\" scope, the 12\" Sky-Watcher has 20% higher resolution and 44% greater light-gathering. The 12\" Sky-Watcher's compact, telescoping optical tube design makes this super aperture 12\" Dob a practical step up for the serious observer.\u003c\/p\u003e\n\u003cp\u003eAs with any large aperture telescope, the performance of the 12\" Sky-Watcher on faint objects will be markedly improved by a dark sky observing site. Light-polluted city and suburban sites are definitely not recommended as the primary observing site for a 12\" scope. Such sites require a nebula (light pollution) filter to take even limited advantage of its immense light-gathering.\u003c\/p\u003e\n\u003cp\u003eWhile it is in deep space observing of galaxies and nebulas from a dark sky observing site that the 12\" Sky-Watcher telescoping truss-tube Dob excels, significant planetary and lunar observing is also within its capability.

It is more stable because the center of gravity is directly over the center of its base, and more portable because it can be broken down into smaller component parts than a fork-mount telescope for easy storage and transportation.\u003c\/p\u003e\n\u003cp\u003eFor astrophotography, the German equatorial mount offers easier balancing; unlimited space at the rear of the telescope tube to mount a long camera equipment train that can't bump into the drive base, as is the case with many fork-mounted scopes; and whole sky access that many fork-mounted scopes can't achieve.\u003c\/p\u003e\n\u003cp\u003eCelestron has looked to update the way that people interact with their equipment. This quest has brought out a new EQ Mount Series, the CGX.

With its full 75 pound payload capacity it will carry Celestron SCT\/HD optical tubes up to 14\" in aperture, as well as virtually any other optical tube and accessory payload weighing up to 75 pounds.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNew features are everywhere in the mount head:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1.

Additional accessory ports built into the dovetail saddle plate of the equatorial head. There are two auxillary ports as well as an autoguider port. The internal cabling of the CGX-L mount works hand in hand with these new ports on the saddle helping the imager in all of us manage our cables.\u003c\/p\u003e\n\u003cp\u003e3. The dovetail saddle plate is longer for added stability and will also accept both Vixen\/AVX and Losmandy\/Celestron D Style dovetails.\u003c\/p\u003e\n\u003cp\u003e4. There are built in home and limit sensors. The home sensor will take the scope back to its home position at any time and the limit sensor will prevent the mount from slewing past a certain point.\u003c\/p\u003e\n\u003cp\u003e5. There are also built-in mechanical hard stops to prevent an instrument from damage should you forget to lock the mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMount drive system:\u003c\/strong\u003e The CGX-L mount head contains 144mm worm wheels in both Right Ascension and Declination. The improved drive system uses a belt-driven worm gear that is spring loaded. The significance of this is it allows the drive to maintain optimum gear mesh for smoother tracking and less backlash.\u003c\/p\u003e\n\u003cp\u003eThe mount requires 2.5 amp 12 VDC power to operate. The maximum 2.5 amp power draw happens only briefly when accelerating to the high speed slewing mode from a standing start. Normal power draw with a well-balanced payload is generally considerably less than half the maximum draw. The mount comes with a car battery cord to operate from the cigarette lighter plug of your car or from a rechargeable 12VDC battery pack. The 17 amp hour capacity Celestron Power Tank #4517V is recommended and will operate the mount all night long without danger of running out of power.\u003c\/p\u003e\n\u003cp\u003eSpecially designed power management electronics deliver constant regulated power to the motor so that it is capable of driving the mount even when your scope not perfectly balanced. This allows the CGX-L to have the payload capacity of that of much larger (and expensive) mounts without sacrificing smooth tracking motion and pointing accuracy across the entire sky.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePolar alignment:\u003c\/strong\u003e To make a casual no-tool polar alignment for visual use quick and easy, there's a latitude scale with large ergonomically-friendly altitude and azimuth adjustment knobs. If serious long exposure astrophotography is in your plans, the special All-Star Polar Alignment software described below allows you to choose any bright alignment star for a software-assisted alignment of the mount's polar axis, even if you can't see the North Star. The mount also has upgraded adjustments for Latitude and Azimuth. Large one hand knobs make moving a full loaded mount head a dream with a simple twist of the wrist.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCounterweight:\u003c\/strong\u003e The CGX-L mount comes with one 22 pound counterweight. The counterweight locks in place on the 5 pound steel counterweight shaft with a single hand-tighten knob, making it easy to rebalance your scope in right ascension if you add heavy photographic accessories. If needed, optional counterweights are available to balance very heavy loads.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHeavy duty tripod:\u003c\/strong\u003e The CGX-L mount's adjustable height Super HD tripod has 2.75\" diameter stainless steel legs. The height adjustment leg locks are on the inside of the tripod legs to keep them from snagging on clothing in the dark. The tripod uses a dual leg support for maximum rigidity, with an upper leg brace to provide an outward preload and a lower leg brace providing inward tension. The upper leg brace forms a convenient tray that holds eyepieces and accessories, as well as a slot to hold your smart phone or tablet, to keep them up out of the dew-soaked grass. This tray is a new design that will allow you to keep it attached while you fold the legs up.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMounting an optical tube:\u003c\/strong\u003e Optical tubes are installed on the CGX-L mount using a slot on the mount head that accepts a Celestron CGE-style\/Losmandy D-plate dovetail or a Celestron AVX\/CG5\/Vixen slide bar. This allows the optical tube to be quickly and precisely balanced fore and aft on the mount in declination, eliminating the need for an extra counterweight to balance a camera or other accessories. Setup and takedown times are exceptionally fast, with large hand-tighten knobs holding the optical tube in place.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNexStar computer hand control:\u003c\/strong\u003e The NexStar computer hand control of the CGX-L mount has a built-in database of more than 40,000 stars, deep space objects, and solar system objects it can locate for you. These include the complete RNGC, Messier, Caldwell, IC, and Abell catalogs; selected SAO stars; the planets, the Moon, and others. The custom database lists of all the most famous deep-sky objects by name and catalog number; the most beautiful double, triple and quadruple stars; variable stars; non-planetary solar system objects; and asterisms. It contains enough fascinating objects to keep you busy observing for the rest of your life.\u003c\/p\u003e\n\u003cp\u003eYou can also store and edit the right ascension and declination of 100 objects of your own choosing, such as the comet and asteroid coordinates published monthly in Astronomy and Sky \u0026amp; Telescope magazines. The computer control can quickly find any of those objects at your command, and track them with high accuracy for visual observing or astrophotography.\u003c\/p\u003e\n\u003cp\u003eAll of the database and scope operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. This display leads you through the steps necessary to line up the scope on the sky, locate objects, control scope functions like the brightness of the hand control display, and much more.

A unique Celestron All-Star Polar Alignment program built into the NexStar hand control helps you do a very precise polar alignment in mere minutes for long exposure astrophotography. It works in both northern and southern hemispheres.\u003c\/p\u003e\n\u003cp\u003eTo accurately polar align your scope, first do a reasonably-accurate mechanical alignment of the mount on the celestial pole by eye. To make this initial alignment quick and easy, there's a latitude scale and fine adjustment controls in both altitude and azimuth. Next, use the mount's standard two-star alignment method to align your scope on the sky. Select a suitable bright star from the NexStar hand control's data base and slew your telescope to the star. A star near the meridian and close to the celestial equator will give the most accurate alignment results. Then, press the Align button on the hand control and select Polar Align: Align Mount from the hand control menu. Your telescope will re-slew to the alignment star and ask you to center it in the eyepiece in order to \"Sync\" on the star. After you sync on the star, your telescope will automatically slew to the position that the star should be at if your mount was accurately polar aligned. Use the mount's altitude and azimuth adjustment knobs to place the star in the center of the eyepiece and press the Align button. That's all there is to it! Your CGE Pro mount is now accurately aligned on the celestial pole.\u003c\/p\u003e\n\u003cp\u003eAlthough the telescope's tracking may be very good after alignment, pointing accuracy may need to be improved (particularly if you are trying to located small objects on a CCD chip), depending on how close your initial mechanical alignment was on the pole, and by much the mount had to be moved during polar alignment. If that's the case, you can easily update your telescope's star alignment in a minute or two if necessary.\u003c\/p\u003e\n\u003cp\u003eOnce polar aligned, several different sky alignment methods are built into the NexStar computer to line up the scope on the celestial sphere, allowing you to choose a level of computer accuracy in automatically finding objects with which you are comfortable. These include 2-Star Align, Solar System Align, Last Alignment, Quick Align, and 1-Star Align,\u003c\/p\u003e\n\u003cp\u003eWith just a standard hand control alignment, the CGX-L computer has the ability to center a star in your telescope's eyepiece or on a CCD chip to within 5 arc minutes. Using the NexStar computer's advanced pointing features (such as Calibration Stars, Sync, and Precise Go-To) further improves the pointing accuracy to as low as 1 arc minute in the desired region of the sky. The high precision pointing subroutine (Precise Go-To) in the computer lets you point accurately at objects that you want to photograph that are too dim to be seen though the scope. Other software features include: database filter limits, a mount hibernate mode, and user-defined slew limits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGPS compatible:\u003c\/strong\u003e In addition, the NexStar computer hand control is GPS-compatible (using an optional inexpensive CN16 GPS module) for full GPS (Global Positioning System) satellite accuracy. Once the scope is approximately polar aligned, the 16-channel CN16 GPS system uses signals from government satellites to calculate the scope's location on earth with an accuracy measured in meters. The system also calculates the current time based on the split second accuracy of the GPS time signals. After the CN16 quickly completes these calculations and enters the information into the computer control for you automatically, the computer then orients the scope with the sky, slews to a pair of guide stars, asks you to confirm that the stars are in the center of the field (and center them if they're not precisely aligned), and then starts finding and tracking over 40,000 objects for you at your command. With the CGX-L go-to mount and the CN16, orienting the scope in time and space on earth and aligning your telescope on the sky becomes almost as easy a task as simply turning on your CGX-L mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTwo-year warranty:\u003c\/strong\u003e All Celestron go-to telescopes have a two-year warranty, double that of competitive go-to scopes.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable class=\"table\" id=\"product-attribute-specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eAperture\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e9.25\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e2350mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e45 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHighest Useful Magnification\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e470x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMotorized Controls\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eComputer GoTo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOptical Coatings\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eStarBright XLT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e0.49 arc seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied Eyepiece\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e40mm 1.25\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTelescope Type\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eSchmidt-Cassegrain\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eView Finder\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e6x30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVisual Limiting Magnitude\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e14.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e2 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eSupplied Accessories: \u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eStarbright XLT fully multicoated 9.25\" f\/10 optics\u003c\/li\u003e\n\u003cli\u003eGo-to fully computerized CGE Pro German equatorial mount with one 22 lb. counterweight\u003c\/li\u003e\n\u003cli\u003eHeavy duty adjustable height metal tripod\u003c\/li\u003e\n\u003cli\u003e40,000+ object computer hand control\u003c\/li\u003e\n\u003cli\u003ePPEC (Permanent Periodic Error Compensation)\u003c\/li\u003e\n\u003cli\u003eRS-232 port for connection to a PC\u003c\/li\u003e\n\u003cli\u003eNexRemote remote telescope control software with RS-232 cable\u003c\/li\u003e\n\u003cli\u003eCCD autoguider port\u003c\/li\u003e\n\u003cli\u003e6 x 30mm finderscope\u003c\/li\u003e\n\u003cli\u003e1.25\" star diagonal\u003c\/li\u003e\n\u003cli\u003e1.25\" 25mm Plössl eyepiece (94x)\u003c\/li\u003e\n\u003cli\u003e12V DC car battery cord\u003c\/li\u003e\n\u003cli\u003eDust covers.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":40221665493065,"sku":"CGXL9","price":5399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/17055.jpg?v=1662967761"},{"product_id":"celestron-cgx-l-1100-11-sct-computerized-go-to-telescope-12071","title":"Celestron CGX-L 1100 11\" SCT Computerized Go-To Telescope 12071","description":"\u003cp\u003eThe Celestron CGX-L 1100 puts the big light-gathering capacity of 11\" Celestron Schmidt-Cassegrain optics on a newly-designed rock-solid 75 pound payload capacity CGX-L go-to German equatorial mount.\u003c\/p\u003e\n\u003cdiv class=\"heading\"\u003e\u003cstrong\u003eThis Celestron CGX-L 1100 telescope has:\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv class=\"heading\"\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv class=\"heading\"\u003e• 75 pound payload capacity high precision CGX-L German equatorial mount \u003cbr\u003e• NexStar go-to computer hand control with 40,000+ object database \u003cbr\u003e• 11\" Schmidt-Cassegrain optics \u003cbr\u003e• StarBright XLT optical multicoatings for the highest possible light transmission\u003cbr\u003e• 9 x 50mm finderscope \u003cbr\u003e• 2-year warranty\u003c\/div\u003e\n\u003cdiv class=\"heading\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003eThe Celestron CGX-L 1100 puts the light-gathering power of an 11\" aperture Schmidt-Cassegrain optical tube -

Using the NexStar computer's advanced pointing features (such as Calibration Stars, Sync, and Precise Go-To) further improves the pointing accuracy to as low as 1 arc minute in the desired region of the sky. The high precision pointing subroutine (Precise Go-To) in the computer lets you point accurately at objects that you want to photograph that are too dim to be seen though the scope. Other software features include: database filter limits, a mount hibernate mode, and user-defined slew limits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGPS compatible:\u003c\/strong\u003e In addition, the NexStar computer hand control is GPS-compatible (using an optional inexpensive CN16 GPS module) for full GPS (Global Positioning System) satellite accuracy. Once the scope is approximately polar aligned, the 16-channel CN16 GPS system uses signals from government satellites to calculate the scope's location on earth with an accuracy measured in meters. The system also calculates the current time based on the split second accuracy of the GPS time signals. After the CN16 quickly completes these calculations and enters the information into the computer control for you automatically, the computer then orients the scope with the sky, slews to a pair of guide stars, asks you to confirm that the stars are in the center of the field (and center them if they're not precisely aligned), and then starts finding and tracking over 40,000 objects for you at your command. With the CGX-L go-to mount and the CN16, orienting the scope in time and space on earth and aligning your telescope on the sky becomes almost as easy a task as simply turning on your CGX-L mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTwo-year warranty:\u003c\/strong\u003e All Celestron go-to telescopes have a two-year warranty, double that of competitive go-to

The improved drive system uses a belt-driven worm gear that is spring loaded. The significance of this is it allows the drive to maintain optimum gear mesh for smoother tracking and less backlash.\u003c\/p\u003e\n\u003cp\u003eThe mount requires 2.5 amp 12 VDC power to operate. The maximum 2.5 amp power draw happens only briefly when accelerating to the high speed slewing mode from a standing start. Normal power draw with a well-balanced payload is generally considerably less than half the maximum draw. The mount comes with a car battery cord to operate from the cigarette lighter plug of your car or from a rechargeable 12VDC battery pack. The 17 amp hour capacity Celestron Power Tank #4517V is recommended and will operate the mount all night long without danger of running out of power.\u003c\/p\u003e\n\u003cp\u003eSpecially designed power management electronics deliver constant regulated power to the motor so that it is capable of driving the mount even when your scope not perfectly balanced. This allows the CGX-L to have the payload capacity of that of much larger (and expensive) mounts without sacrificing smooth tracking motion and pointing accuracy across the entire sky.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePolar alignment:\u003c\/strong\u003e To make a casual no-tool polar alignment for visual use quick and easy, there's a latitude scale with large ergonomically-friendly altitude and azimuth adjustment knobs. If serious long exposure astrophotography is in your plans, the special All-Star Polar Alignment software described below allows you to choose any bright alignment star for a software-assisted alignment of the mount's polar axis, even if you can't see the North Star. The mount also has upgraded adjustments for Latitude and Azimuth. Large one hand knobs make moving a full loaded mount head a dream with a simple twist of the wrist.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCounterweight:\u003c\/strong\u003e The CGX-L 1400 comes with three 22 pound counterweights.  Each counterweight locks in place on the 5 pound steel counterweight shaft with a single hand-tighten knob, making it easy to rebalance your scope in right ascension if you add heavy photographic accessories. If needed, optional counterweights are available to balance very heavy loads.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHeavy duty tripod:\u003c\/strong\u003e The CGX-L mount's adjustable height Super HD tripod has 2.75\" diameter stainless steel legs. The height adjustment leg locks are on the inside of the tripod legs to keep them from snagging on clothing in the dark. The tripod uses a dual leg support for maximum rigidity, with an upper leg brace to provide an outward preload and a lower leg brace providing inward tension. The upper leg brace forms a convenient tray that holds eyepieces and accessories, as well as a slot to hold your smart phone or tablet, to keep them up out of the dew-soaked grass. This tray is a new design that will allow you to keep it attached while you fold the legs up.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMounting an optical tube:\u003c\/strong\u003e Optical tubes are installed on the CGX-L mount using a slot on the mount head that accepts a Celestron CGE-style\/Losmandy D-plate dovetail or a Celestron AVX\/CG5\/Vixen slide bar. This allows the optical tube to be quickly and precisely balanced fore and aft on the mount in declination, eliminating the need for an extra counterweight to balance a camera or other accessories. Setup and takedown times are exceptionally fast, with large hand-tighten knobs holding the optical tube in place.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNexStar computer hand control:\u003c\/strong\u003e The NexStar computer hand control of the CGX-L mount has a built-in database of more than 40,000 stars, deep space objects, and solar system objects it can locate for you. These include the complete RNGC, Messier, Caldwell, IC, and Abell catalogs; selected SAO stars; the planets, the Moon, and others. The custom database lists of all the most famous deep-sky objects by name and catalog number; the most beautiful double, triple and quadruple stars; variable stars; non-planetary solar system objects; and asterisms. It contains enough fascinating objects to keep you busy observing for the rest of your life.\u003c\/p\u003e\n\u003cp\u003eYou can also store and edit the right ascension and declination of 100 objects of your own choosing, such as the comet and asteroid coordinates published monthly in Astronomy and Sky \u0026amp; Telescope magazines. The computer control can quickly find any of those objects at your command, and track them with high accuracy for visual observing or astrophotography.\u003c\/p\u003e\n\u003cp\u003eAll of the database and scope operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. This display leads you through the steps necessary to line up the scope on the sky, locate objects, control scope functions like the brightness of the hand control display, and much more. It shows you basic information about the object being viewed (such as the object's name, catalog designation, type, magnitude, and so forth). In addition to this basic information, there is enhanced information on over 200 of the most note-worthy objects. The display can also show you the right ascension and declination coordinates at which the scope is aimed.\u003c\/p\u003e\n\u003cp\u003eAlignment on the sky and go-to accuracy: No polar alignment finderscope is available for the CGX-L mount, nor is any needed. A unique Celestron All-Star Polar Alignment program built into the NexStar hand control helps you do a very precise polar alignment in mere minutes for long exposure astrophotography. It works in both northern and southern hemispheres.\u003c\/p\u003e\n\u003cp\u003eTo accurately polar align your scope, first do a reasonably-accurate mechanical alignment of the mount on the celestial pole by eye. To make this initial alignment quick and easy, there's a latitude scale and fine adjustment controls in both altitude and azimuth. Next, use the mount's standard two-star alignment method to align your scope on the sky. Select a suitable bright star from the NexStar hand control's data base and slew your telescope to the star. A star near the meridian and close to the celestial equator will give the most accurate alignment results. Then, press the Align button on the hand control and select Polar Align: Align Mount from the hand control menu. Your telescope will re-slew to the alignment star and ask you to center it in the eyepiece in order to \"Sync\" on the star. After you sync on the star, your telescope will automatically slew to the position that the star should be at if your mount was accurately polar aligned. Use the mount's altitude and azimuth adjustment knobs to place the star in the center of the eyepiece and press the Align button. That's all there is to it! Your CGE Pro mount is now accurately aligned on the celestial pole.\u003c\/p\u003e\n\u003cp\u003eAlthough the telescope's tracking may be very good after alignment, pointing accuracy may need to be improved (particularly if you are trying to located small objects on a CCD chip), depending on how close your initial mechanical alignment was on the pole, and by much the mount had to be moved during polar alignment. If that's the case, you can easily update your telescope's star alignment in a minute or two if necessary.\u003c\/p\u003e\n\u003cp\u003eOnce polar aligned, several different sky alignment methods are built into the NexStar computer to line up the scope on the celestial sphere, allowing you to choose a level of computer accuracy in automatically finding objects with which you are comfortable. These include 2-Star Align, Solar System Align, Last Alignment, Quick Align, and 1-Star Align,\u003c\/p\u003e\n\u003cp\u003eWith just a standard hand control alignment, the CGX-L computer has the ability to center a star in your telescope's eyepiece or on a CCD chip to within 5 arc minutes. Using the NexStar computer's advanced pointing features (such as Calibration Stars, Sync, and Precise Go-To) further improves the pointing accuracy to as low as 1 arc minute in the desired region of the sky. The high precision pointing subroutine (Precise Go-To) in the computer lets you point accurately at objects that you want to photograph that are too dim to be seen though the scope. Other software features include: database filter limits, a mount hibernate mode, and user-defined slew limits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGPS compatible:\u003c\/strong\u003e In addition, the NexStar computer hand control is GPS-compatible (using an optional inexpensive CN16 GPS module) for full GPS (Global Positioning System) satellite accuracy. Once the scope is approximately polar aligned, the 16-channel CN16 GPS system uses signals from government satellites to calculate the scope's location on earth with an accuracy measured in meters. The system also calculates the current time based on the split second accuracy of the GPS time signals. After the CN16 quickly completes these calculations and enters the information into the computer control for you automatically, the computer then orients the scope with the sky, slews to a pair of guide stars, asks you to confirm that the stars are in the center of the field (and center them if they're not precisely aligned), and then starts finding and tracking over 40,000 objects for you at your command. With the CGX-L go-to mount and the CN16, orienting the scope in time and space on earth and aligning your telescope on the sky becomes almost as easy a task as simply turning on your CGX-L mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTwo-year warranty:\u003c\/strong\u003e All Celestron go-to telescopes have a two-year warranty, double that of competitive go-to scopes.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable class=\"table\" id=\"product-attribute-specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eAperture\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e14\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e3910mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/11\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e52.6 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHighest Useful Magnification\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e650x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMotorized Controls\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eComputerized GoTo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e215 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOptical Coatings\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eStarBright XLT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e0.32 arc seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied Eyepiece\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e40mm Plossl\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTelescope Type\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eSchmidt-Cassegrain\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eView Finder\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e9x50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVisual Limiting Magnitude\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e15.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e2 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eSupplied Accessories: \u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eStarbright XLT fully multicoated 14\" f\/11 Faster-compatible optics\u003c\/li\u003e\n\u003cli\u003eGo-to fully computerized CGE Pro German equatorial mount with three 22 lb. counterweights\u003c\/li\u003e\n\u003cli\u003eHeavy duty adjustable height metal tripod\u003c\/li\u003e\n\u003cli\u003e40,000+ object computer hand control\u003c\/li\u003e\n\u003cli\u003ePPEC (Permanent Periodic Error Compensation)\u003c\/li\u003e\n\u003cli\u003eRS-232 port for connection to a PC\u003c\/li\u003e\n\u003cli\u003eNexRemote remote telescope control software with RS-232 cable\u003c\/li\u003e\n\u003cli\u003eCCD autoguider port\u003c\/li\u003e\n\u003cli\u003e9 x 50mm finderscope\u003c\/li\u003e\n\u003cli\u003e2\" mirror-type star diagonal with 1.25\" eyepiece adapter\u003c\/li\u003e\n\u003cli\u003e1.25\" 40mm Plössl eyepiece (98x)\u003c\/li\u003e\n\u003cli\u003e12V DC car battery cord\u003c\/li\u003e\n\u003cli\u003eDust covers.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":40221665591369,"sku":"CGXL14","price":8999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/17058.jpg?v=1662967765"},{"product_id":"astro-tech-8-f-4-imaging-newtonian-optical-tube","title":"Astro-Tech 8\" f\/4 Imaging Newtonian Optical Tube","description":"\u003cp\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif;
