The trusses are designed to have an equal amount of flexure, which allows the optics to stay on a common optical axis. 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. The net result is that the optical elements stay in collimation regardless of the orientation of the telescope, including passing through the meridian during imaging.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: medium;\"\u003e The truss tubes are made of a light weight\/high strength woven carbon fiber-reinforced composite material with extremely low thermal expansion characteristics.

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.

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.

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).

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.

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.

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. Installing the optical tube on the mount is quick and easy, even in the dark. The optical tube locks securely in place with no tools needed.\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 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. It easily adjusts in height with no tools needed. The no-tool lock knobs that adjust the leg height of the tripod are on the inside of the legs so they won't snag on clothing in the dark, a thoughtful touch that's sure to be appreciated. Spreader bars lock the legs firmly open when the tripod is set up. The tripod includes a convenient accessory tray that attaches to the spreader bars to hold your eyepieces and accessories close at hand and up out of the dew-soaked grass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTwo year warranty:\u003c\/strong\u003e As an expression of Celestron's confidence in the quality of their products, the AstroMaster is protected by Celestron's two-year limited warranty against flaws in materials and workmanship.\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\"\u003e5.1\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e650mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e25 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHighest Useful Magnification\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e217x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMotorized Controls\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eSingle Axis Motor Drive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e0.89 arc seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied Eyepiece\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e20mm and 10mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTelescope Type\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eReflector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eView Finder\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eBuilt-On StarPointer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVisual Limiting Magnitude\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e13.1\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\u003e130mm aperture Newtonian reflector optical tube with 1.25\" rack and pinion focuser\u003c\/li\u003e\n\u003cli\u003eCG3 equatorial mount with split ring\/dovetail quick release tube mount system, altitude and azimuth adjustment micrometer controls, setting circles, battery-operated right ascension motor drive, manual slow-motion controls, and locks on both axes\u003c\/li\u003e\n\u003cli\u003e10mm (65X) and erect image 20mm (32.5X) eyepieces\u003c\/li\u003e\n\u003cli\u003eNon-magnifying straight-through red dot finder\u003c\/li\u003e\n\u003cli\u003eAdjustable height stainless steel tripod with accessory tray\u003c\/li\u003e\n\u003cli\u003eOperating instructions\u003c\/li\u003e\n\u003cli\u003eTheSky Level 1 CD-ROM star-charting software.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":40221662969929,"sku":"AM130MD","price":389.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/15241.jpg?v=1662967690"},{"product_id":"astro-tech-8-f-8-ritchey-chretien-astrograph-carbon-fiber-tube","title":"Astro-Tech 8\" f\/8 Ritchey-Chrétien Astrograph, Carbon Fiber Tube","description":"\u003cp\u003eThe Astro-Tech AT8RC is the \u003cem\u003efirst \u003c\/em\u003eaffordable 8\" Ritchey-Chrétien with premium features available to the amateur astronomer who is into serious deep space imaging. \u003cem\u003eSky \u0026amp;

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.

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.

The drive rail and its attached drawtube are thereby supported over most of their length at all times, rather than by a conventional Crayford focuser's two sets of small contact area roller bearings. This system distributes the drive force evenly over the entire drawtube, without concentrating it on a few small contact points. The result is a very rigid drawtube with essentially zero flexure and no wear (much less flat spots or uneven wear) on the focuser drawtube.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: medium;\"\u003eTo fine-tune the long back focus of the AT10RC to the requirements of your camera and equipment train, three threaded extension rings (two 1\" in length and one 2\") are provided to install singly or in combination between the AT10RC rear cell and the focuser. These provide a flex-free solid metal extension that changes the distance between the focuser and the rear cell. This lets you accommodate the varying back-focus requirements of DSLR-type camera imaging versus long equipment train CCD imaging.

While not specifically designed to work with Ritchey-Chrétien astrographs, images taken with the field flattener by Astro-Tech R-C owners have shown that the Astro-Tech 2\" field flattener works remarkably well with these advanced coma-free reflectors as well as with refractors. 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.

The steel drive rail rides in a self-lubricating track that extends almost the entire length of the focuser body. The drive rail and its attached drawtube are thereby supported over most of their length at all times, rather than by a conventional Crayford focuser's two sets of small contact area roller bearings.

The optical tube is black-finished 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 AVX8N outside in the cold air of late fall or winter.\u003c\/p\u003e\n\u003cp\u003eThe scope's tube end rings are sturdy die cast aluminum, to protect the tube during transport and provide exceptionally rigid support for the optics.

With its patented collapsible tube design, this compact 8\" Dobsonian sets up in minutes in your back yard as well as fit into any car for transporting to a dark sky observing site. It is truly the ultimate in portability and performance.\u003c\/p\u003e\n\u003cp\u003eThe collapsible truss tube design combines ease of use, extreme portability, and consistent performance in an affordable package. Unlike other truss tube designs, the 8\" Sky-Watcher collapsible Dobsonian does not need to be completely disassembled when not in use. The secondary mirror cage and trusses slide down onto the mirror box, allowing all the optics to be lifted out of the scope base as a single unit with the trusses attached. The two compact assemblies (optics and base) can then be transported separately and reassembled and ready to use in just minutes.\u003c\/p\u003e\n\u003cp\u003eThe Sky-Watcher Dob is easy to collimate once set up, and it holds its collimation throughout the evening! Its patented tension control handle allows you to add or reduce tension in altitude when changing eyepieces, to compensate for the added weight of today's massive wide field eyepieces.\u003c\/p\u003e\n\u003cp\u003eThe Sky-Watcher SynScan™ AZ hand control allows you point your telescope at a specific object, or even tour the best objects visible in the night sky, at the touch of a button. The user-friendly menu system allows automatic slewing to over 42,900+ objects. Even if you have never used a telescope before, you can master its variety of features in only a few observing sessions. The patented dual encoder design allows the telescope to be moved manually whenever the user wishes - but with no need to re-align on the sky after you have moved the scope.\u003c\/p\u003e\n\u003cp\u003eThe 8\" Sky-Watcher Dobsonian SynScan combines the convenience and affordability of the traditional Dobsonian with the convenience of a computerized go-to telescope

Dobsonian reflectors, this 6\" Sky-Watcher Classic Dob gives you more light-gathering for your visual observing dollar than any other telescope type. It is a \"light bucket\" that can show you faint deep space objects that are simply invisible in smaller scopes.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eIts visual limiting magnitude makes this 6\" Sky-Watcher a natural for observing faint nebulas, galaxies, and star clusters, particularly from a dark sky site. It's long focal length also makes it a fantastic planetary and lunar telescope.\u003c\/p\u003e\n\u003cp\u003eWith parabolic mirror Newtonian optics and very thin (only 0.5mm) secondary mirror spider vanes to reduce diffraction, the Moon and planets are sharp and well-defined . . . and very bright. You might need a neutral density filter to cut down the image brightness, particularly when lunar observing. The Moon and planets show high contrast and none of the violet halo of spurious color you find in similarly-priced smaller aperture achromatic refractors.\u003c\/p\u003e\n\u003cp\u003eThe 6\" Sky-Watcher Dobsonian is easy to get to your favorite observing site, too, whether that be your own back yard or a dark sky site miles out of town. The Sky-Watcher breaks down into two components - a 48\" long 15 pound optical tube and a 25 pound wooden rocker box altazimuth base. It weighs only 40 pounds fully assembled. And assembling the 6\" Sky-Watcher Dob takes just a moment, with no tools needed. Simply lift the optical tube, rest its circular altitude bearings in the semi-circular cutouts in the sides of the rocker box, put in an eyepiece, and you're ready to observe.\u003c\/p\u003e\n\u003cp\u003eThe optical tube rides on Teflon altitude and azimuth bearings. It moves smoothly in altitude and azimuth to manually find and track objects at the touch of a finger. The 6\" Sky-Watcher Dob is equipped with an altitude tension control handle. This lets you adjust the tension in altitude with a simple twist of the wrist to let you compensate for differing eyepiece weights to keep the optical tube from sinking when changing from a lighter to a heavier eyepiece.\u003c\/p\u003e\n\u003cp\u003eOther features include an eyepiece tray, two 1.25\" Plössl eyepieces (48x and 120x), a 6 x 30mm straight-through finderscope, and a 2\" Crayford focuser with a 1.25\" eyepiece adapter. Your 6\" Sky-Watcher Dob comes with everything you need to start observing immediately.\u003c\/p\u003e\n\u003cp\u003eSimply made, but with precision optics, this Sky-Watcher 6\" Classic Dobsonian reflector \"light bucket\" will reward you with bright deep space and solar system views and years of trouble-free observing enjoyment.\u003c\/p\u003e\n\u003ch2\u003eTech

also be used for pleasing visual observing. It incorporates a superbly-figured multi-coated borosilicate optical glass mirror-set. Additionally, the tube length has been slightly shortened to optimize performance for wide-field prime-focus photography. Even better field edge performance for deep space astrophotography, and visual use, can be achieved by adding the Sky-Watcher Quattro coma corrector.\u003c\/p\u003e\n\u003cp\u003eThis Sky-Watcher 10\" Quattro imaging Newtonian is ultra-fast and incredibly simple to use. The f\/4 optical system allows the user to capture wide field images of faint deep space objects such as nebulae, open clusters, and galaxies over six times faster than using an f\/10 system. This gives you the ability to acquire more images in less time. The Newtonian optical design is one of the most basic, and therefore trouble free, systems available to astrophotographers.\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\"\u003e10\"\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\/4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e33 pounds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e33 pounds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOptical Coatings\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eFully Multi-Coated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied Eyepiece\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eNone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTelescope Type\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eReflector\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\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","brand":"Sky-Watcher","offers":[{"title":"Default Title","offer_id":40481978548297,"sku":"S11220","price":1325.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/files\/Quattro250_Main_1800x1800_374f5147-26b3-4e03-9d8c-23ffc275ad68.webp?v=1723057008"},{"product_id":"sky-watcher-10-flextube-synscan-250p-go-to-collapsible-dobsonian-reflector","title":"Sky-Watcher 10\" Flextube Synscan 250P Go-To Collapsible Dobsonian Reflector","description":"\u003cp\u003eThis 10\" Sky-Watcher go-to collapsible Dob will find and track over 42,000 celestial objects for you at the touch of a button or two.

Unlike other truss tube designs, the 10\" Sky-Watcher collapsible Dobsonian does not need to be completely disassembled when not in use. The secondary mirror cage and trusses slide down onto the mirror box, allowing all the optics to be lifted out of the scope base as a single unit with the trusses attached. The two assemblies (optics and base) can then be transported separately and reassembled and ready to use in just minutes.\u003c\/p\u003e\n\u003cp\u003eThe Sky-Watcher 10\" Dob is easy to collimate once set up, and it holds its collimation throughout the evening!

The user-friendly menu system allows automatic slewing to over 42,900+ objects. Even if you have never used a telescope before, you can master its variety of features in only a few observing sessions. The patented dual encoder design allows the telescope to be moved manually whenever the user wishes - but with no need to re-align on the sky after you have moved the

Despite its very large aperture, its patented collapsible tube design lets you set up this big 16\" Dobsonian in minutes in your back yard as well as fit into virtually any car for transporting to a dark sky observing site. It is truly the ultimate in portability and performance in a scope of such substantial aperture.\u003c\/p\u003e\n\u003cp\u003eThe collapsible truss tube design combines ease of use, extreme portability, and consistent big-scope performance in an affordable package. Unlike other truss tube designs, the 16\" Sky-Watcher collapsible Dobsonian does not need to be completely disassembled into multiple components when not in use. There is no need to struggle with a collection of truss tubes that have to be packed and reassembled separately.\u003c\/p\u003e\n\u003cp\u003eThe secondary mirror cage with its attached trusses slides down onto the mirror box, allowing all the optics to be lifted out of the scope base as a single unit with the trusses attached.

Its patented tension control handle allows you to add or reduce tension in altitude when changing eyepieces, to compensate for the added weight of today's massive wide field eyepieces.\u003c\/p\u003e\n\u003cp\u003eThe Sky-Watcher SynScan™ AZ hand control allows you point your telescope at a specific object, or even tour the best objects visible in the night sky, at the touch of a button. The user-friendly menu system allows automatic slewing to over 42,900+ objects. Even if you have never used a telescope before, you can master its variety of features in only a few observing sessions. The patented dual encoder design allows the telescope to be moved manually whenever the user wishes - but with no need to re-align on the sky after you have moved the scope.\u003c\/p\u003e\n\u003cp\u003eThe 16\" Sky-Watcher Dobsonian SynScan combines the convenience and affordability of the traditional Dobsonian with the convenience of a computerized go-to

It shows you faint deep space objects that are simply invisible in smaller scopes. Its visual limiting magnitude of 14 makes this 8\" Sky-Watcher a natural for observing faint nebulas, galaxies, and star clusters, particularly from a dark sky site.\u003c\/p\u003e\n\u003cp\u003eWith parabolic mirror Newtonian optics and very thin (only 0.5mm) secondary mirror spider vanes to reduce diffraction, the Moon and planets are sharp and well-defined. They show high contrast and none of the violet halo of spurious color you find in similarly-priced smaller aperture achromatic refractors.\u003c\/p\u003e\n\u003cp\u003eYou get the best of both observing worlds with this 8\" Sky-Watcher Dob: great light gathering for picking out the faint fuzzies outside our solar system, and great resolution for seeing all the detail on the Moon, planets, and comets inside the solar neighborhood.\u003c\/p\u003e\n\u003cp\u003eThe 8\" Sky-Watcher Dobsonian is easy to get to your favorite observing site, too, whether that be your own back yard or a dark sky site miles out of town. The Sky-Watcher breaks down into two components - a 48\" long 24 pound optical tube and a 25 pound wooden rocker box altazimuth base. It weighs only 49 pounds fully assembled. And assembling the 8\" Sky-Watcher Dob takes just a moment, with no tools needed. Simply lift the optical tube, rest its circular altitude bearings in the semi-circular cutouts in the sides of the rocker box, put in an eyepiece, and you're ready to observe.\u003c\/p\u003e\n\u003cp\u003eThe optical tube rides on Teflon altitude and azimuth bearings. It moves smoothly in altitude and azimuth to manually find and track objects at the touch of a finger. The 8\" Sky-Watcher Dob is equipped with an altitude tension control handle. This lets you adjust the tension in altitude with a simple twist of the wrist to let you compensate for differing eyepiece weights to keep the optical tube from sinking when changing from a lighter to a heavier eyepiece.\u003c\/p\u003e\n\u003cp\u003eOther features include an eyepiece tray, two 1.25\" Plössl eyepieces (48x and 120x), a 9 x 50mm straight-through finderscope, and a 2\" Crayford focuser with a 1.25\" eyepiece adapter. Your 8\" Sky-Watcher Dob comes with everything you need to start observing immediately.\u003c\/p\u003e\n\u003cp\u003eSimply made, but with precision optics, this Sky-Watcher 8\" traditional solid tube Dobsonian reflector \"light bucket\" will reward you with bright and sharp deep space and solar system views and years of trouble-free observing enjoyment.\u003c\/p\u003e\n\u003ch2\u003eTech

Light-polluted city or suburban sites may require adding a light pollution filter to get the most from this scope's superb deep space capabilities.\u003c\/p\u003e\n\u003cp\u003eWith parabolic mirror Newtonian optics and very thin (only 0.5mm) secondary mirror spider vanes to reduce diffraction, the Moon and planets are sharp and well-defined . . . and very bright.

The Moon and planets show high contrast and none of the violet halo of spurious color you find in similarly-priced smaller aperture achromatic refractors.\u003c\/p\u003e\n\u003cp\u003eThe 10\" Sky-Watcher Dobsonian is easy to get to your favorite observing site, too, whether that be your own back yard or a dark sky site miles out of town. The Sky-Watcher breaks down into two components - a 48\" long 30 pound optical tube and a 26 pound wooden rocker box altazimuth base. It weighs only 56 pounds fully assembled. And assembling the 10\" Sky-Watcher Dob takes just a moment, with no tools needed. Simply lift the optical tube, rest its circular altitude bearings in the semi-circular cutouts in the sides of the rocker box, put in an eyepiece, and you're ready to observe.\u003c\/p\u003e\n\u003cp\u003eThe optical tube rides on Teflon altitude and azimuth bearings. It moves smoothly in altitude and azimuth to manually find and track objects at the touch of a finger. The 10\" Sky-Watcher Dob is equipped with an altitude tension control handle. This lets you adjust the tension in altitude with a simple twist of the wrist to let you compensate for differing eyepiece weights to keep the optical tube from sinking when changing from a lighter to a heavier eyepiece.\u003c\/p\u003e\n\u003cp\u003eOther features include an eyepiece tray, two 1.25\" Plössl eyepieces (48x and 120x), a 9 x 50mm straight-through finderscope, and a 2\" Crayford focuser with a 1.25\" eyepiece adapter.

The diagonal mirror is attached directly to the Maksutov corrector, instead of being supported by a traditional Newtonian reflector's spider vanes. This eliminates the diffraction spikes typical of spider vanes to improve contrast. The Maksutov spherical corrector lens is made of premium Schott crown optical glass and is fully multi-coated on both sides with multiple layers of anti-reflection materials for high light transmission and good contrast.

has changed the hobby quite as much as the Dobsonian Telescope. Before the popularization of John Dobson's altazimuth mount design with low center of gravity combined with a Newtonian optical assembly, the vast majority of amateur telescopes consisted of small telescopes with small mounts - which made them difficult to use for serious deep sky observations by beginners. Large commercial telescopes could certainly do the job but were relatively expensive. The ingenious combination of simple yet effective mechanisms with big-aperture Newtonian optics gives the Dobsonian Telescope worldwide popularity, and this telescope design typically offers the largest aperture per dollar of any telescope type.\u003c\/p\u003e\n\u003cp\u003eDisassembly of the scope without tools ensures a trouble-free transport of this great scope even in very small cars. The entire structure has been optimized for maximum stiffness with minimal weight.

Details on planets and deep sky objects will be visible even for inexperienced observers. Many star clusters are resolved to the core, spiral structure in distant galaxies is visible, and the complex matrix of bright and dark nebulae are an unforgettable experience. Oversize altitude (16.5-inch with adjustable clutch) and azimuth (13-inch) bearings allow for smooth operation. Easy-to-adjust collimation mechanisms for primary and secondary mirrors require no additional tools and only one person is a unique feature of this design.\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\"\u003e10\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e1270mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e44.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e59.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOptical Coatings\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eAluminum with Quartz Overcoat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTelescope Type\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eReflector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eView Finder\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eIluminated Red Dot\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\"\u003e1 year, extendable to lifetime\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\u003cp\u003e\u003cspan\u003eTwo-Speed 2-inch Rack \u0026amp; Pinion Focuser with 1.25-inch Adapter; LED Red Dot Finder, Collimation Assist Tool; Flexible Light Weight Light Baffle; Two Primary Mirror Fans with Battery Pack; Instructions\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":40481980481609,"sku":"ES10D","price":1089.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/dob1045-00_full_hot_product_2016_1493x_1e3b6338-ae68-4157-b219-585c7d7cce2c.jpg?v=1722008170"},{"product_id":"explore-scientific-12-truss-tube-dobsonian-telescope-generation-ii","title":"Explore Scientific 12\" Truss Tube Dobsonian Telescope Generation II","description":"\u003cp data-end=\"402\" data-start=\"327\"\u003e\u003cstrong data-end=\"402\" data-start=\"327\"\u003eExplore Scientific Generation II 12-inch Truss Tube Dobsonian Telescope\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-end=\"795\" data-start=\"404\"\u003eThe Explore Scientific Generation II 12-inch Truss Tube Dobsonian is designed for serious visual observers who want big-aperture performance in a portable, easy-to-use package.

tabletop Dobsonian that combines simplicity, portability, and impressive optical performance in a single, user-friendly package. Whether you’re a first-time stargazer or a seasoned backyard astronomer looking for a grab-and-go companion, the Heritage 130 punches well above its weight in both aperture and capability.\u003c\/p\u003e\n\u003ch3 class=\"\" data-end=\"862\" data-start=\"789\"\u003e130mm Parabolic Optics – Serious Light-Gathering in a Compact Package\u003c\/h3\u003e\n\u003cp class=\"\" data-end=\"1337\" data-start=\"864\"\u003eAt the heart of the Heritage 130 is a 130mm (5.1\") parabolic primary mirror with a focal length of 650mm (f\/5). This is not a spherical mirror as found in many beginner scopes, but a true parabolic mirror that eliminates spherical aberration for sharper, more accurate views. The f\/5 focal ratio provides wide fields of view—ideal for sweeping the Milky Way, observing open clusters like the Pleiades, or catching large nebulae like the Orion Nebula with stunning contrast.\u003c\/p\u003e\n\u003cp class=\"\" data-end=\"1674\" data-start=\"1339\"\u003eThis level of aperture allows the Heritage 130 to reveal hundreds of deep-sky objects under dark skies. You can expect bright views of globular clusters, galaxies such as M31 (Andromeda), and impressive detail on the Moon and planets. Saturn’s rings, Jupiter’s cloud bands and moons, and even the ice caps of Mars are all within reach.\u003c\/p\u003e\n\u003ch3 class=\"\" data-end=\"1732\" data-start=\"1676\"\u003eTabletop Dobsonian Mount – Rock-Steady and Intuitive\u003c\/h3\u003e\n\u003cp class=\"\" data-end=\"2081\" data-start=\"1734\"\u003eSky-Watcher’s tabletop Dobsonian base is engineered for smooth, friction-based motion in both altitude and azimuth. It allows for intuitive “point-and-look” operation, with no motors, electronics, or counterweights to worry about. Just place it on a sturdy surface like a table, bench, or even a milk crate, and you’re ready to observe in seconds.\u003c\/p\u003e\n\u003cp class=\"\" data-end=\"2331\" data-start=\"2083\"\u003eThe mount uses tension knobs to adjust and lock the altitude motion, offering the right balance between stability and freedom of movement.

This f\/5 optical system (750mm focal length) offers a wide field of view and excellent contrast, making it ideal for both low-power sweeping and moderate magnification planetary viewing. With 33% more light-gathering capability than a 130mm scope, it pulls in dimmer galaxies, nebulae, and star clusters with noticeably more clarity.\u003c\/p\u003e\n\u003cp class=\"\" data-end=\"1835\" data-start=\"1444\"\u003eThe optics are housed in a collapsible open-tube design, borrowed from Sky-Watcher’s larger Flextube models. This unique feature makes the telescope incredibly portable without sacrificing collimation stability or optical quality. The included adjustable strut system holds collimation well and allows the telescope to collapse down to just 15 inches in length—perfect for storage or travel.\u003c\/p\u003e\n\u003ch3 class=\"\" data-end=\"1860\" data-start=\"1837\"\u003eMount and Usability\u003c\/h3\u003e\n\u003cp class=\"\" data-end=\"2231\" data-start=\"1862\"\u003eThe tabletop Dobsonian mount is intuitive, stable, and smooth in both altitude and azimuth motion. There are no motors, electronics, or batteries to get in the way—just point and observe. The tensioning system is adjustable, allowing you to fine-tune the movement to your preference and avoid the common pitfalls of stickiness or backlash that can plague lesser mounts.\u003c\/p\u003e\n\u003cp class=\"\" data-end=\"2483\" data-start=\"2233\"\u003eBeginners will appreciate the simplicity, while more experienced users will love the freedom and responsiveness of manual navigation.

A red-dot finder helps you zero in on your targets with minimal fuss.

Add in built-in WiFi, full GoTo capability via the SynScan app, and a collapsible optical tube, and you’ve got a telescope that’s equally at home in the backyard or under dark skies far from city lights.\u003c\/p\u003e\n\u003ch3 data-start=\"924\" data-end=\"955\" class=\"\"\u003eBig Views from a Small Tube\u003c\/h3\u003e\n\u003cp data-start=\"957\" data-end=\"1388\" class=\"\"\u003eAt the heart of the Virtuoso GTi 130P is a 130mm (5.1\") f\/5 parabolic mirror capable of gathering 345% more light than the average 60mm starter scope. This aperture lets you resolve rich lunar detail, track down faint Messier objects, and split tight double stars. The fast f\/5 focal ratio delivers wide, immersive fields of view—perfect for open clusters, sweeping the Milky Way, and even glimpsing large nebulae under dark skies.\u003c\/p\u003e\n\u003cp data-start=\"1390\" data-end=\"1763\" class=\"\"\u003eUnlike most budget reflectors, the 130P doesn’t skimp on optics. The primary mirror is parabolic, not spherical, meaning you'll enjoy sharper images across the field, especially at higher magnifications. \u003c\/p\u003e\n\u003ch3 data-start=\"1765\" data-end=\"1802\" class=\"\"\u003eGoTo, Guided, and Ready to Travel\u003c\/h3\u003e\n\u003cp data-start=\"1804\" data-end=\"2287\" class=\"\"\u003eWhat truly sets the Virtuoso GTi 130P apart is its built-in GoTo system, driven by Sky-Watcher’s trusted SynScan technology. Instead of a traditional hand controller, the Virtuoso GTi uses WiFi to connect to your smartphone or tablet. Simply download the free SynScan app for iOS or Android, and you can control the telescope with intuitive taps and swipes. Choose from over 10,000 celestial objects in the app’s database, and the scope will automatically slew and track your target.\u003c\/p\u003e\n\u003cp data-start=\"2289\" data-end=\"2616\" class=\"\"\u003eThe dual-axis motors keep your object centered for extended viewing or casual astrophotography with a smartphone.

Set it on a sturdy picnic table, portable crate, or even a custom Dob base if desired. Rubber feet and a smooth azimuth bearing ensure solid performance in the field. Despite its motorized functionality, the scope still offers full manual operation. You can unlock the clutches and move it by hand without harming the motors—a feature that makes impromptu stargazing even easier.\u003c\/p\u003e\n\u003ch3 data-start=\"3060\" data-end=\"3101\" class=\"\"\u003eCollapsible Tube, Maximum Portability\u003c\/h3\u003e\n\u003cp data-start=\"3103\" data-end=\"3419\" class=\"\"\u003ePortability is one of the biggest perks of the 130P design.

With a generous 6\" aperture, fully motorized GoTo tracking, and a collapsible strut-tube design, this tabletop reflector is equally at home on a backyard patio or a dark sky site. Whether you're a beginner looking for your first real telescope or an experienced observer in need of a portable powerhouse, the GTi 150P delivers exceptional optical performance and convenience without the bulk or price tag of traditional GoTo systems.\u003c\/p\u003e\n\u003ch4 data-start=\"976\" data-end=\"1010\" class=\"\"\u003e6\" of Serious Light Gathering\u003c\/h4\u003e\n\u003cp data-start=\"1012\" data-end=\"1381\" class=\"\"\u003eAt the heart of the GTi 150P is a 150mm (6\") f\/5 Newtonian reflector.
