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.

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.

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. Low contrast banding and details in Saturn's atmosphere begin to make themselves apparent, as well. Lunar features less than one mile across become visible, while Jupiter's four Galilean moons start to show as tiny discs.\u003c\/p\u003e\n\u003cp\u003eTaking advantage of the weight-saving sophistication of its telescoping truss-tube design, the 49.5 pound Sky-Watcher 8\" Dobsonian makes it practical for one individual on his or her own to explore the heavens with a truly big scope, whether from a back yard or a distant dark sky observing site.

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. 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 10\" Sky-Watcher telescoping truss-tube Dob excels, significant planetary and lunar observing is also within its capability. All you need is a neutral density eyepiece filter to cut down the immense brightness of solar system objects seen through this \"light bucket.\"\u003c\/p\u003e\n\u003cp\u003eTaking advantage of the weight-saving sophistication of its telescoping truss-tube design, the 60.5 pound Sky-Watcher 10\" Dobsonian makes it practical for one individual on his or her own to explore the heavens with a truly big scope, whether from a back yard or a distant dark sky observing site.

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.

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.

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.

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. All you need is a neutral density eyepiece filter to cut down the immense brightness of solar system objects seen through this \"light bucket.\"\u003c\/p\u003e\n\u003cp\u003eTaking advantage of the weight-saving sophistication of its telescoping truss-tube design, the 86.9 pound Sky-Watcher 12\" Dobsonian makes it practical for almost any individual on his or her own to explore the heavens with a truly big scope, whether from a back yard or a distant dark sky observing site. This Sky-Watcher 12\" telescoping truss-tube Dobsonian reflector will keep you happily observing the faint and distant outer reaches of the Universe for many years to come.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable class=\"table\"

The dew shield slows the formation of dew on the lens in cold weather to extend your undisturbed observing time. It also improves the contrast, similar to the effect of the lens shade on a camera lens, when observing during the day or when there is excessive ambient light at night, such as a neighbor's backyard security light.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThread-on doublet field flattener:\u003c\/strong\u003e When you are ready for imaging, the Esprit 80mm includes a doublet field flattening lens that can be threaded onto the optical tube to transform your scope into an exceptional wide-field imaging Instrument. Using optical grade glass and multicoatings on all air-to-glass lens surfaces, the field flattener provides sharp, in-focus stars across a large fully-illuminated 33mm image circle that is ideal for most APS-C sensor size DSLR cameras and for CCD cameras using the popular Kodak 8300 sensor. Back focus is 75mm. A Canon EOS camera adapter (the most popular DSLR camera brand for astronomical imaging) is standard equipment. Optional Celestron M48 camera adapters are available for Nikon and Sony\/Minolta Maxxum cameras.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual speed 2.7\" rack and pinion focuser:\u003c\/strong\u003e The precision-made and mechanically ultra-smooth, backlash-free, rack and pinion focuser has a giant 2.7\" diameter drawtube with a 2\" accessory adapter. This rotatable focuser offers dual-speed focusing and has an engraved focusing scale. There are two coarse focusing knobs. The right knob has a smaller concentric knob with 10:1 reduction gear microfine focusing over the full 60mm focuser travel. This provides exceptionally precise image control during high magnification visual observing and critical DSLR or CCD imaging. The large focus knobs have ribbed gripping surfaces so they are easy to operate, even while wearing gloves or mittens in cold weather. A lock knob lets you adjust the tension on the drawtube to accommodate varying eyepiece\/photo accessory loads, as well as firmly lock in a photographic focus.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2\" dielectric star diagonal:\u003c\/strong\u003e The supplied standard equipment 2\" mirror star diagonal of the Esprit 80mm slips into the focuser drawtube's 2\" eyepiece\/accessory holder.

Using optical grade glass and multicoatings on all air-to-glass lens surfaces, the field flattener provides sharp, in-focus stars across a large fully-illuminated 40mm image circle. This is ideal for DSLR cameras (APS-C sensors and even those with 35mm equivalent sensors, although there will be some vignetting at the corners of a full-sized sensor) and for virtually all CCD cameras. Back focus is 69.8mm. A Canon EOS camera adapter (the most popular DSLR camera brand for astronomical imaging) is standard equipment.

The lens trio delivers crisp, high-definition wide-field and high power images of solar system and deep space objects alike. The views are unmarred by the faint but annoying halo of unfocused violet light (chromatic aberration) often seen around bright stars and solar system objects in other large aperture fast focal ratio doublet and triplet refractors. A separate thread-on glass doublet field flattener provides pin-point star images across the entire 43mm image circle for superb astrophotography.\u003c\/p\u003e\n\u003cp\u003eThe 150mm Sky-Watcher Esprit triplet utilizes the most modern top-quality optical glasses and computer-optimized fabricating techniques to deliver the ultimate in high-definition astronomical observing and imaging. Each lens blank is individually inspected for purity and absence of striations and other image-degrading imperfections. Each element is then ground and pitch polished to exacting standards of optical fabrication and performance by highly skilled opticians. It is laser-tested on an optical bench to rigidly controlled optical standards. The result is a high-quality, diffraction-limited 6\" refractor optical system that consistently performs to the theoretical limits of its aperture - one that will give you years of imaging and visual observing satisfaction.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures of this Sky-Watcher refractor . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApochromatic ED triplet refractor optics:\u003c\/strong\u003e 150mm (5.9\") aperture, 1050mm focal length, f\/7 focal ratio.

The dew shield slows the formation of dew on the lens in cold weather to extend your undisturbed observing time. It also improves the contrast, similar to the effect of the lens shade on a camera lens, when observing during the day or when there is excessive ambient light at night, such as a neighbor's backyard security light.

Using optical grade glass, and multicoatings on all air-to-glass lens surfaces, the field flattener provides sharp, in-focus stars across a large fully-illuminated 43mm image circle. This is ideal for DSLR cameras (even those with 35mm equivalent sensors, although there may be some very minor vignetting at the extreme corners of a full-sized sensor) and for virtually all CCD cameras. Back focus is 100mm. A Canon EOS camera adapter (the most popular DSLR camera brand for astronomical imaging) is standard equipment. Optional Celestron M48 camera adapters are available for Nikon and Sony\/Minolta Maxxum cameras.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual speed 3.4\" rack and pinion focuser:\u003c\/strong\u003e The precision-made and mechanically ultra-smooth, backlash-free, rack and pinion focuser has a giant 3.4\" diameter drawtube with a 2\" accessory adapter.

The right knob has a smaller concentric knob with 10:1 reduction gear microfine focusing over the full 87mm focuser travel. This provides exceptionally precise image control during high magnification visual observing and critical DSLR or CCD imaging. The large focus knobs have ribbed gripping surfaces so they are easy to operate, even while wearing gloves or mittens in cold weather.

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

Despite its size, its patented collapsible tube design lets you set up this big 14\" 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 14\" 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. 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 14\" 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 14\" Sky-Watcher Dobsonian SynScan combines the convenience and affordability of the traditional Dobsonian with the convenience of a computerized go-to

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. 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 16\" 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 16\" Sky-Watcher Dobsonian SynScan combines the convenience and affordability of the traditional Dobsonian with the convenience of a computerized go-to

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

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. Your 10\" 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 10\" traditional 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 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\"\u003e1200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/4.7\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e30 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHighest Useful Magnification\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e300x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eTube: 28 lbs Base: 25 lbs Assembled: 53 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e0.46 arc seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied Eyepiece\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e25mm and 10mm Plossl Eyepieces\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\"\u003e9 x 50mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVisual Limiting Magnitude\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e14.5\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":40481978843209,"sku":"S11620","price":869.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/files\/RS1756_S11620_Classic250_LeftProfile-scr_1800x1800_9eb68249-d100-4ac6-ac5e-7ecfca8b0bd8.webp?v=1723057523"},{"product_id":"sky-watcher-skymax-102-102mm-f-12-75-maksutov-cassegrain-optical-tube","title":"Sky-Watcher Skymax 102 102mm f\/12.75 Maksutov-Cassegrain Optical Tube S11510","description":"\u003cp\u003eThe Sky-Watcher 102mm Maksutov-Cassegrain is an inexpensive step up from a 90mm Mak.

deep space imaging and viewing.\u003c\/p\u003e\n\u003cp\u003eThe exciting 7.5\" f\/5.3 Mak-Newt from Sky-Watcher is just what astrophotographers and serious deep space visual observers have been looking for. It uses a hybrid optical system that combines a Newtonian reflector's parabolic primary mirror with a Maksutov's spherical front corrector. The result is a system that corrects for both coma and spherical and chromatic aberrations.\u003c\/p\u003e\n\u003cp\u003eThe Maksutov-Newtonian design provides large aperture\/fast focal ratio apochromatic performance similar to that of a fine refractor with exceptional field correction in a compact and affordable package. The small secondary obstruction yields a sharper and higher contrast image than a Schmidt-Cassegrain - both visually and photographically. The fast f\/5.3 focal ratio makes the Sky-Watcher Mak-Newt an excellent wide field photographic instrument for deep sky imaging.\u003c\/p\u003e\n\u003cp\u003eThe optical tube is made of rolled steel, powder-coated gloss black, with gold fleck accents. The front and rear cells are painted die-cast aluminum. The front cell is perforated to allow faster cool down of the Maksutov corrector. A precision 2\" Crayford focuser is standard. The smooth backlash-free focuser has both coarse and ultra-fine (10:1 ratio) focusing knobs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures of this 180mm Sky-Watcher Maksutov-Cassegrain . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaksutov-Newtonian optics:\u003c\/strong\u003e 7.5\" (190mm) aperture, 1000mm focal length, f\/5.3. The optical system uses Pyrex mirrors (a parabolic primary and a diagonal flat). The parabolic primary mirror helps correct for spherical aberration. 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. Internal baffling reduces stray light to further improve the contrast.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFocuser:\u003c\/strong\u003e Dual-speed 2\" Crayford type with 10:1 ratio fine focusing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2\" eyepiece:\u003c\/strong\u003e The 36x eyepiece is a fully multi-coated three-element Sky-Watcher 28mm LET design with a long 20mm eye relief and a twist-up eyecup.

The built in ST-4 Autoguider port turns this mount into an astrophotography powerhouse, allowing you to utilize most of today's best autoguiders. Using the integrated RS232 port, you can control the telescope from your computer and take advantage of today's most advanced astronomy software. With a weight capacity of 44 lbs, the EQ6-R can handily support an optical tube, imaging accessories and camera.  Sky-Watcher includes an illuminated polar finderscope to aid the polar alignment process. The finderscope features a circular grid reticle for the northern hemisphere, consistent with todays popular polar alignment apps. For astronomers in the southern hemisphere, the constellation Octans is built into the reticle as well.

apochromatic ED doublet optics. Combined with the moderate focal ratio, this results in images with visibly less chromatic aberration than you find in refractors with a similar aperture but faster focal ratio. In addition to the lack of chromatic aberration's annoying halo of unfocused violet light around bright stars and solar system objects, there is no loss in contrast such as you will find in reflector and catadioptric scopes that have a secondary or diagonal mirror hanging in the light path to scatter light..\u003c\/p\u003e\n\u003cp\u003eThe 100mm Sky-Watcher doublet optics are even more appealing when you consider that this Sky-Watcher apo is loaded with features other manufacturers charge extra for (or don't even have available) - such as an 8 x 50mm right-angle finderscope, a 2\" dielectric star diagonal with 1.25\" and 2\" compression ring accessory holders, two 1.25\"  eyepieces (25mm and 5mm); and a foam-lined aluminum-clad carrying case.\u003c\/p\u003e\n\u003cp\u003eThe Sky-Watcher PRO 100ED has enough premium high contrast\/high resolution optical performance to let you use it on an altazimuth or equatorial mount as the heart of your observing system. Its light weight (only 6.6 pounds) doesn't require a big and expensive mount, so it's easy to afford and easy to take out and set up for observing on a moment's notice. Considering its surprisingly low price for an apochromatic doublet, adding in the extra features you get at no extra cost, and in view of the great optical performance that comes as standard equipment, the 100mm Sky-Watcher PRO 100ED is a terrific buy!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures of this telescope . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eApochromatic ED doublet refractor optics: 100mm (3.94\") aperture, 900mm focal length, f\/9 focal ratio.  The ED element is precision-polished from high grade ED (Extra-low Dispersion) glass. This ED element produces superior sharpness and color correction by minimizing the chromatic aberration, the \"false\" color fringing seen around bright objects when light rays pass through standard crown-and-flint doublet objectives. The result is to reduce spurious color halos and fringing to vanishingly low levels.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFully multicoated optics:\u003c\/strong\u003e Each air-to-glass surface in the Sky-Watcher Evostar 100ED doublet objective lens has MHC (Metallic High-Transmission Coating) antireflection multicoatings on all air-to-glass surfaces for high light transmission, minimal light scatter, and excellent contrast.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInternal light baffles:\u003c\/strong\u003e Contrast-enhancing internal light baffles in the tube and focuser drawtube and a specially darkened tube interior provide dark sky backgrounds and high terrestrial contrast.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDew shield:\u003c\/strong\u003e The supplied dew shield slows the formation of dew on the lens in cold weather to extend your undisturbed observing time. It also improves the contrast, similar to the effect of the lens shade on a camera lens, when observing during the day or when there is excessive ambient light at night, such as a neighbor's backyard security light. The 6.6 pound optical tube measures 36.22\" long, including the dew shield.

This provides exceptionally precise image control during high magnification visual observing and critical imaging. The large focus knobs have ribbed gripping surfaces so they are easy to operate, even while wearing gloves or mittens in cold weather. Lock knobs lets you adjust the tension on the drawtube to accommodate varying eyepiece\/photo accessory loads, as well as firmly lock in a photographic focus.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2\" dielectric star diagonal:\u003c\/strong\u003e The supplied standard equipment 2\" mirror star diagonal of the Evostar 100ED slips into the focuser drawtube's 2\" eyepiece\/accessory holder.

Like the optics, the tube is beautifully crafted using aluminum and finished with a black diamond metal-flake finish.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eUsing a doublet refractor instead of a triplet has some advantages: less glass means less weight, less weight means a less expensive telescope, so you can dedicate more money for your camera or laptop while benefiting from a lightweight astrophotography rig.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eTo protect your investment, Sky-Watcher includes a heavy duty aluminum carry case with the Evostar 150DX.\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\"\u003e150mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e1200mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e22 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e22 lbs\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\"\u003eRefractor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eView Finder\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eNone\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 \u003cbr\u003e\u003c\/p\u003e\n\u003ctable class=\"spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eS11195\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e050234111959\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eOptical Info\u003c\/th\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Design\u003c\/td\u003e\n\u003ctd\u003eED Doublet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLens Coatings\u003c\/td\u003e\n\u003ctd\u003eFully Multi-Coated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTrue Aperture (mm)\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Aperture (mm)\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eF\/Ratio\u003c\/td\u003e\n\u003ctd\u003e8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Length (mm)\u003c\/td\u003e\n\u003ctd\u003e1200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eObservational Info\u003c\/th\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDawes Limit\u003c\/td\u003e\n\u003ctd\u003e0.77\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRayleigh Limit\u003c\/td\u003e\n\u003ctd\u003e0.93\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLimiting Mag.\u003c\/td\u003e\n\u003ctd\u003e13.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Magnification\u003c\/td\u003e\n\u003ctd\u003e21\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Magnification\u003c\/td\u003e\n\u003ctd\u003e295\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Gathering (compared to next size down)\u003c\/td\u003e\n\u003ctd\u003e71%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eGeneral Info\u003c\/th\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocuser\u003c\/td\u003e\n\u003ctd\u003e3.4\" Dual Speed R \u0026amp;

Built in clutch knobs on both axis allow for easy movement by hand. With certain mounts when you move the scope by hand you will lose your computer alignment.  Not with this one.  The dual encoders will keep exact axis aligment when you unlock the mount and move the scope manually. Once you are locked in and tracking the DC servo motors run quietly and have minimum vibration. The mount runs on eight user-supplied AA batteries.\u003c\/p\u003e\n\u003cp\u003eSo, you want to know what exactly the SynScan App does? One this it doesn't do is cost money.  It is free at the app store.  The app will control the mount wirelessly allowing you to align, move, control from your device.  The GPS unit will automatically update your location, day, date, time making it even easier to line up your mount.  Once you get it all aligned the SynScan has a fantastic tour abilty taking you around the night sky to the best objects that are available.  It has three tracking rates (solar, lunar, and sidereal) as well as 10 slewing speeds.\u003c\/p\u003e\n\u003cp\u003eAnd in closing, we can talk about the 5.3 pound tripod and pier extension.  The tripod is an adjustable height tripod with aluminum legs.  Its maximum height is 43.3\" and the extension pier will give you a few more inches making night time viewing a tad more comfortable while keeping vibration at a minimum.  The tripod legs will spread to 42.3 inches and are held in place with a spreader tray that is designed to hold personal effects or accessories while you are out observing.  The feet of the AZ-GTi are spiked to increase stability when you are on different types of terrain or soft ground.\u003c\/p\u003e\n\u003ch2\u003eTech
