The most popular and easiest to use is Celestron's exclusive SkyAlign no-guesswork technology. After turning on the scope, simply enter the date and time and your location, then point the scope at any three bright stars, or at two bright stars and a planet or the Moon (you don't even have to know which stars and planet you're looking at, and you don't have to know and locate specific stars as you do with other alignment programs). The NexStar computer will use the stars you've pointed at to model the sky overhead. Once it knows what the sky looks like, it's ready to find and track over 45,000 objects for you at your command. \u003c\/p\u003e\n\u003cp\u003eThe scope can be operated with its ergonomically designed hand control conveniently docked in its fork arm storage compartment.  You can also remove the control and its coiled connecting cord from the fork arm for hand-held use. There's no need to worry about wrapping the cord around the mount as you walk around the scope to observe different parts of the sky. The hand control plugs into the fork arm rather than the base, so it always moves with the scope.\u003cbr\u003e\u003cbr\u003eAll of the database and scope operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. There are 19 fiber optic backlit LED buttons to make it easy for you to control the computer without affecting your dark-adapted vision. If you are new to astronomy, you may wish to start by using the computer's built-in Sky Tour feature. This program commands the NexStar 8 to find the most interesting objects in the sky and automatically slews to them one at a time for you to observe at your leisure.\u003c\/p\u003e\n\u003cp\u003eNo matter what level of experience you start from, however, the NexStar 8 will unfold all the wonders of the Universe for you, your family, and your friends.

The Star Pointer is the quickest and easiest way to point your telescope exactly to the desired object in the sky. It's like having a laser pointer that appears to shine directly onto the night sky. No need to worry about the inverted images that you see through traditional finders. Just align the red dot seen through the Star Pointer with the desired star in the sky.

The optical tube is offset slightly so that its center of mass is over the axis of rotation of the mount, keeping the optical tube properly balanced in all planes. Built-in friction clutches in altitude and azimuth keep the optical tube fixed in place when eyepieces or accessory loads are changed. No mechanical locking levers or knobs are required.\u003cbr\u003e\u003cbr\u003eThe 11 lb. mount includes slewing\/tracking motors in both altitude and azimuth. There are nine user-selectable slewing\/centering\/guiding speeds - 6°\/second; 3°\/second; 1.5°\/second; and 128, 64, 16, 8, 2, and 1x sidereal. There are also three selectable drive rates - sidereal, solar, and lunar. The drives normally operate in the altazimuth mode (right\/left up\/down) to locate and track objects for visual use and casual solar system photography. A compartment in the drive base accepts eight user-supplied AA batteries for powering the scope in the field. The Celestron Power Tank Lithium (#PTL12V) is a highly recommended optional 7 amp-hour capacity multi-purpose rechargeable 12V DC battery that can provide several nights worth of observing from a single charge. To conserve battery life, an optional 2.5 Amp AC adapter (#2338N) is available to operate the scope from household current during backyard use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComputer control:\u003c\/strong\u003e The supplied NexStar computer hand control has a 45,000+ object database of stars and objects that it can locate and track for you. The database includes the complete RNGC, Messier, Caldwell, IC, and Abell catalogs; selected SAO stars (including the best variable stars and multiple star systems); the planets; the Moon; and more. You can also store and edit the right ascension and declination coordinates of 400 objects of your own choosing, such as favorite deep space objects or the comet and asteroid coordinates published monthly in Astronomy and Sky \u0026amp; Telescope magazines.\u003cbr\u003e\u003cbr\u003eYou have several ways to have the NexStar computer find celestial objects for you. The most popular and easiest to use is Celestron's exclusive SkyAlign no-guesswork technology. After turning on the scope, simply enter the date and time and your location, then point the scope at any three bright stars, or at two bright stars and a planet or the Moon (you don't even have to know which stars and planet you're looking at, and you don't have to know and locate specific stars as you do with other alignment programs). The NexStar computer will use the stars you've pointed at to model the sky overhead. Once it knows what the sky looks like, it's ready to find and track over 45,000 objects for you at your command.\u003c\/p\u003e\n\u003cp\u003eThe computer hand control includes a built-in RS-232 communication port allowing you to use a CCD autoguider for deep space photography. It also lets you use popular astronomy software to control the NexStar from a lap top or personal computer for remote control point-and-click slewing. The hand control software can now be flash-upgraded from the Celestron website. You can always have the most up-to-date control program, database, and software features simply by downloading the new programs as they are posted.\u003c\/p\u003e\n\u003cp\u003eThe scope can be operated with its ergonomically designed hand control conveniently docked in its fork arm storage compartment. You can also remove the control and its coiled connecting cord from the fork arm for hand-held use. There's no need to worry about wrapping the cord around the mount as you walk around the scope to observe different parts of the sky. The hand control plugs into the fork arm rather than the base, so it always moves with the scope.\u003cbr\u003e\u003cbr\u003eAll of the database and scope operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. There are 19 fiber optic backlit LED buttons to make it easy for you to control the computer without affecting your dark-adapted vision. If you are new to astronomy, you may wish to start by using the computer's built-in Sky Tour feature. This program commands the NexStar 6 SE to find the most interesting objects in the sky and automatically slews to them one at a time for you to observe at your leisure.\u003c\/p\u003e\n\u003cp\u003eNo matter what level of experience you start from, however, the NexStar 6 SE will unfold all the wonders of the Universe for you, your family, and your friends.

The NexStar 5 SE combines legendary 5\" Celestron optics with 21st century computerized go-to technology at a most affordable price.\u003c\/p\u003e\n\u003cp\u003eIn 1982, we sold the original Celestron C5 and tripod for $954.90 - without a go-to computer, without multicoated optics, and without a drive that can run off flashlight batteries all night long. Adjusting for inflation, that equals greater than $3100 in todays dollars! How times have changed. This 5\" Celestron NexStar 5 SE has all those features - and more – for less than 1982's C5 cost!\u003c\/p\u003e\n\u003cp\u003eThe NexStar 5 SE is a great alternative to costly competitive 5\" Maksutovs. While it has the same light-gathering capacity as a 5\" Mak, its faster focal ratio means a wider field and brighter images with any given eyepiece than a Mak. And it's priced far less than competitive 5\" Maks that don't have the clear optical advantage of Celestron's state-of-the-art XLT multicoatings. Across the full photo\/visual spectrum from 400nm to 750nm, independent laboratory tests show the new Starbright XLT coatings are 16% brighter than even Celestron's legendary original Starbright multicoatings - long the industry standard.\u003c\/p\u003e\n\u003cp\u003eThe Celestron NexStar 5 SE comes with a red dot finder, tripod, 25mm Plössl eyepiece, flashlight battery-operated dual-axis motor drives, and a go-to computerized hand control that will find over 45,000 stars and deep space objects for you automatically.\u003c\/p\u003e\n\u003cp\u003eNew SkyAlign technology makes it easy to line up this Celestron telescope on the sky so it can find celestial objects for you. You don't have to level the scope or point it north, or know which stars are which. Simply point the scope at any three bright stars, or at two bright stars and a planet or the Moon (you don't even have to know which stars and planet you're looking at). The telescope will then know how the sky is laid out that night and will be ready to find and track nearly 40,000 objects for you at your command.\u003c\/p\u003e\n\u003cp\u003eThe Celestron NexStar 5 SE has all the features and optical performance you need to keep you happily observing for years to come - and a classic color scheme that will draw admiring glances wherever you take your scope.

One-knob quick-release attachment to fork arm for fast assembly in the field. Guaranteed diffraction-limited optical performance. Celestron orange finish. Rear cell uses the standard SCT thread, so all SCT photo and visual accessories can be used without having to add a special adapter, as is the case with many Maksutovs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStarbright XLT fully-multicoated:\u003c\/strong\u003e This state-of-the-art coatings package includes high reflectivity multilayer aluminum mirrors enhanced with titanium dioxide for high reflectivity, plus a unique combination of magnesium fluoride and hafnium dioxide antireflection coatings on both sides of the Schmidt corrector lens. Starbright XLT multicoatings give you higher light transmission for brighter deep space images and shorter exposure times during photography. They also visibly increase the contrast on subtle lunar, planetary, and nebula details when compared with a scope with standard coatings or multicoatings.

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

The drives normally operate in the altazimuth mode (right\/left up\/down) to locate and track objects for visual use and casual solar system photography.\u003c\/p\u003e\n\u003cp\u003eIf long exposure deep space photography is planned, the tripod includes a built-in wedge that quickly converts the scope to equatorial operation, although deep space imaging will realistically be limited by the scope's relatively small aperture and long focal ratio.\u003cbr\u003e\u003cbr\u003eA compartment in the drive base accepts eight user-supplied AA batteries for powering the scope in the field. The Celestron Power Tank Lithium (#PTL12V) is a highly recommended optional 7 amp-hour capacity multi-purpose rechargeable 12V DC battery that can provide several nights worth of observing from a single charge. To conserve battery life, an optional 2.5 Amp AC adapter (#2338N) is available to operate the scope from household current during backyard use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComputer control:\u003c\/strong\u003e The supplied NexStar computer hand control has a nearly 40,000 object database of stars and objects that it can locate and track for you. The database includes the complete RNGC, Messier, and Caldwell catalogs; selected SAO stars (including the best variable stars and multiple star systems); the planets; the Moon; and more. You can also store and edit the right ascension and declination coordinates of 200 objects of your own choosing, such as favorite deep space objects or the comet and asteroid coordinates published monthly in \u003cem\u003eAstronomy\u003c\/em\u003e and \u003cem\u003eSky \u0026amp; Telescope\u003c\/em\u003e magazines.\u003cbr\u003e\u003cbr\u003eYou have several ways to have the NexStar computer find celestial objects for you. The most popular and easiest to use is Celestron's exclusive SkyAlign no-guesswork technology. After turning on the scope, simply enter the date and time and your location, then point the scope at any three bright stars, or at two bright stars and a planet or the Moon (you don't even have to know which stars and planet you're looking at, and you don't have to know and locate specific stars as you do with other alignment programs). The NexStar computer will use the stars you've pointed at to model the sky overhead. Once it knows what the sky looks like, it's ready to find and track nearly 40,000 objects for you at your command. Not all of the objects may be easily visible, however, due to the scope's limited aperture.\u003c\/p\u003e\n\u003cp\u003eThe computer hand control includes a built-in RS-232 communication port allowing you to use a CCD autoguider for deep space photography. It also lets you use popular astronomy software to control the NexStar from a lap top or personal computer for remote control point-and-click slewing. The hand control software can now be flash-upgraded from the Celestron website. You can always have the most up-to-date control program, database, and software features simply by downloading the new programs as they are posted.\u003c\/p\u003e\n\u003cp\u003eThe scope can be operated with its ergonomically designed hand control conveniently docked in its fork arm storage compartment. You can also remove the control and its coiled connecting cord from the fork arm for hand-held use. There's no need to worry about wrapping the cord around the mount as you walk around the scope to observe different parts of the sky. The hand control plugs into the fork arm rather than the base, so it always moves with the scope.\u003cbr\u003e\u003cbr\u003eThe computer includes a camera control software program and a camera shutter cable. These let you remotely take a series of timed exposures using your digital SLR camera (connected to the scope by an appropriate camera adapter). This can be very useful during lunar or solar eclipses and during occultation events, since you won't have to miss any of the sights while worrying about the operation of your camera.\u003cbr\u003e\u003cbr\u003eAll of the database and scope operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. There are 19 fiber optic backlit LED buttons to make it easy for you to control the computer without affecting your dark-adapted vision. If you are new to astronomy, you may wish to start by using the computer's built-in Sky Tour feature. This program commands the NexStar 4 SE to find the most interesting objects in the sky and automatically slews to them one at a time for you to observe at your leisure.\u003cbr\u003e\u003cbr\u003eNo matter what level of experience you start from, however, the NexStar 4 SE will unfold many of the wonders of the Universe for you, your family, and your friends.

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.

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 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.

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. 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\"

Lunt H-alpha refractors for solar observing. That said, it should also be noted that the eyepiece works equally well for daytime terrestrial observing and nighttime observing with virtually any standard (non-solar) telescope. For these latter situations, the Lunt zoom offers the convenient ability to precisely match the observing magnification to daytime seeing conditions, as well as a virtually infinite number of medium to high power nighttime magnifications in a single reasonably-priced eyepiece.\u003c\/p\u003e\n\u003cp\u003eAs with virtually all zooms, the apparent field of view of this Lunt Solar zoom decreases somewhat as the focal length increases. This generally results in a 20% narrower field of view at low powers than you can achieve with similar focal length single magnification eyepieces. This is just the reverse of what most people expect from eyepieces - which is a wider field at lower powers, where you're usually observing larger objects that don't need as much magnification to fit in the eyepiece field. The Lunt Solar zoom's apparent field of view ranges from 53° at the highest power 7.2mm focal length to a 40° field at the lowest power 21.5mm focal length.\u003c\/p\u003e\n\u003cp\u003eEye relief of the zoom's 7 lens\/4 group optical system is specified at 15mm.

A safety groove cut into its barrel will catch the thumbscrew of your focuser or star diagonal and keep the eyepiece from falling to the ground should the thumbscrew accidentally loosen during use.

To insure a perfect seal, Explore Scientific tests every eyepiece in one meter of water for 30 minutes before shipping.\u003c\/p\u003e\n\u003cp\u003eInternally sealing the eyepiece and purging it with inert, dry nitrogen gas prevents internal fogging in the eyepiece when observing at sub-freezing temperatures. For observers in dusty climates, sealing keeps wind-blown dust and fine particulates from getting into the eyepiece body. For observers in very humid climates, sealing prevents the growth of fungus on the internal lens elements. For all observers, complete sealing maximizes the life of the internal optical coatings and makes the eyepiece easier to clean, as there is no risk of cleaning solution migrating from the top of the lens and seeping around edges to be trapped in between elements.\u003c\/p\u003e\n\u003cp\u003eThe 20mm Explore Scientific eyepiece, has high contrast, comfortable eye relief, and full field sharpness - with well-controlled astigmatism, field curvature, and lateral color. Its nine element optical system (using lenses of dense crown, light crown, dense flint, and lanthanum rare earth optical glasses) is designed for maximum field\/medium power deep space use with telescopes having focal ratios down as low as f\/4. It is exceptionally effective on nebulas with fast f\/ratio reflectors, such as Dobsonians, as it gives both an immense field and a bright exit pupil (almost 4.5mm with the typical f\/4.5 Dob). Its very wide field also makes it convenient for moderate power lunar and globular cluster observing with Dobsonians, as you have much longer to observe before the planet drifts out of the field and the scope has to be repositioned than you do with a 60° or 70° (or even 82°) field eyepiece. In addition to Dobs, the new 20mm Explore Scientific Explore Scientific is marvelous for observing open clusters, nebulas, galaxy clusters, and globular clusters with \u003cem\u003eany \u003c\/em\u003etelescope capable of using a 2\" eyepiece.\u003c\/p\u003e\n\u003cp\u003eThe 100° apparent field of this new 20mm Explore Scientific eyepiece is nearly 50% larger in area than an 82° field eyepiece. You \u003cem\u003ecould \u003c\/em\u003eget a similar true field with a longer focal length (but narrower apparent field) conventional eyepiece, but the 20mm Explore Scientific Explore Scientific has the benefits of the higher power and darker sky backgrounds that are inherent in its shorter focal length. \u003c\/p\u003e\n\u003cp\u003eThere is a soft roll down eyecup to shield your eye from ambient light (from a neighbor's security light, for example) and improve the image contrast. With an eye relief of 14.5mm, the 20mm Explore Scientific would normally somewhat vignette the field of view for eyeglass wearers. However, since the 100° field is so wide that you can't see the full field without having to move your head from side to side to take it all in anyway, vignetting in the conventional sense is not a problem.\u003c\/p\u003e\n\u003cp\u003eThe 20mm Explore Scientific fits 2\" focusers only.

It's the widest field of view available in any commercial eyepiece. An astronomy first from Explore Scientific, the 120° apparent field of this new 9mm Explore Scientific shows more than twice the sky area of an 82° eyepiece and even a whopping 44% larger area than a 100° eyepiece.\u003c\/p\u003e\n\u003cp\u003eThe prototype 9mm was field-tested for the first time at Starfest in Canada, August 2011. Experienced astronomers who waited in line to get a chance to view through the hyperwide 120° Explore Scientific 9mm were stunned by the full-immersion observing experience. Even when compared with a 9mm 100° field eyepiece, the difference was \"quite palpable,\" to quote one experienced observer. The telescope seemed to truly disappear in the 120° field, bringing them face to face with the Universe in an intimate and personal way never before possible. It's an awe-inspiring observing experience you can repeat for yourself every night you go out with your scope.\u003c\/p\u003e\n\u003cp\u003eThis deep sky eyepiece, the first of its kind for astronomy, produces a highly corrected field across its entire 120° apparent field.

Internally sealing the eyepiece and purging it with inert, dry argon gas (which has lower permeability through the eyepiece's polymer seals than nitrogen) prevents internal fogging in the eyepiece when observing at sub-freezing temperatures. For observers in dusty climates, sealing keeps wind-blown dust and fine particulates from getting into the eyepiece body. For observers in very humid climates, sealing prevents the growth of fungus on the internal lens elements. For all observers, complete sealing maximizes the life of the internal optical coatings and makes the eyepiece easier to clean, as there is no risk of cleaning solution migrating from the top of the lens and seeping around edges to be trapped in between elements.\u003c\/p\u003e\n\u003cp\u003eThe 9mm Explore Scientific eyepiece, has high contrast and full field sharpness - with well-controlled astigmatism, field curvature, and lateral color. Its twelve element\/eight group optical system (using lenses of dense crown, light crown, dense flint, and lanthanum rare earth optical glasses with 15-layer multicoatings on all air\/glass surfaces) is designed for maximum field\/high power deep space use with telescopes having focal ratios down to f\/4 and below.\u003c\/p\u003e\n\u003cp\u003eIts very wide field makes this 9mm eyepiece convenient for observing with Dobsonians, as you have much longer to observe before an object drifts out of the field and the scope has to be repositioned than you do with a 70° or 82° (or even 100°) field eyepiece.\u003c\/p\u003e\n\u003cp\u003eThere is a soft rolldown eyecup to shield your eye from ambient light (from a neighbor's security light, for example) and improve the image contrast.

It is exceptionally effective on nebulas with fast f\/ratio reflectors, such as Dobsonians, as it gives both an immense field and a bright exit pupil (over 5.5mm with the typical f\/4.5 Dob). Its very wide field also makes it convenient for moderate power lunar and globular cluster observing with Dobsonians, as you have much longer to observe before the planet drifts out of the field and the scope has to be repositioned than you do with a 60° or 70° (or even 82°) field eyepiece. In addition to Dobs, the new 25mm Explore Scientific Explore Scientific is marvelous for observing open clusters, nebulas, galaxy clusters, and globular clusters with any telescope capable of using a 2\" eyepiece.\u003c\/p\u003e\n\u003cp\u003eThe 100° apparent field of this new 25mm Explore Scientific eyepiece is nearly 50% larger in area than an 82° field eyepiece.

A safety groove is machined into the 2\" chrome barrel to engage your focuser thumbscrew. This helps prevent the eyepiece from falling should the thumbscrew accidentally loosen while observing.\u003c\/p\u003e\n\u003cp\u003eThis individually serial numbered Explore Scientific eyepiece is backed by a limited one year warranty, which will be extended to an Explore Scientific \u003cem\u003etransferable lifetime\u003c\/em\u003e limited warranty when its warranty card is registered with Explore Scientific within 60 days of purchase.

You can slew to all of the best celestial objects with a simple tap on your smart phone or tablet.\u003c\/p\u003e\n\u003cp\u003eSimply connect your smart phone or tablet to your NexStar Evolution's built-in wireless network, and you can explore the universe with Celestron's mobile app for iOS and Android. The app has a database of over 120,000 celestial objects for you to explore, including a specially selected list of 220 of the best deep sky and solar system objects that you will come back to enjoy again and again.\u003c\/p\u003e\n\u003cp\u003eYou can use the app's planetarium interface to view the night sky in real time or to display a list of the best celestial objects that are visible to you based on your time and location. You can then have your Evolution 6 slew to the object of your choice at speeds of up to four degrees per second, center it precisely in the eyepiece field, and then track it flawlessly while you observe and enjoy at your leisure. In addition, Celestron's proprietary SkyAlign alignment procedure is built right into the Celestron mobile app, so you can have your scope set up and ready to observe within minutes. (If you don't have a wireless device, or your smart phone or tablet runs out of juice in the field, a conventional hand control is included so you can still enjoy your scope.)\u003c\/p\u003e\n\u003cp\u003eCelestron engineers designed the NexStar Evolution 6 based on years of customer feedback. Its upgraded single fork arm design offers many thoughtful features that combine to provide you the best possible experience out under the stars. For example, forget about buying boxes of AA batteries to power the scope, or a bulky external battery pack. For the first time ever on a consumer telescope, the NexStar Evolution 6 includes its own built-in rechargeable lithium-ion battery. You can enjoy stargazing for up to 10 hours on a single charge, then recharge it at home using the supplied AC adapter. You can even use your NexStar Evolution's built-in USB charge port to top off the other devices in your life that need to stay powered on during an observing session.\u003c\/p\u003e\n\u003cp\u003eLarge, ergonomic handles make setting up your NexStar Evolution 6 quick and painless. With a total weight of only 35.4 lbs, the Evolution 6 is easy to transport, whether it's out to the backyard for a quick half hour of observing or away on an all-night observing session at a distant dark sky site. The adjustable height stainless steel tripod features lines etched on the legs to help you achieve a level, uniform height for your telescope without guesswork. Manual clutches in both altitude and azimuth give you the flexibility to manually point the telescope when it is powered off.\u003c\/p\u003e\n\u003cp\u003eYou get two quality Plössl eyepieces to give you observing options right out of the box. If you expand your eyepiece collection, you can store up to seven eyepieces in the 2 accessory trays, one on the tripod and one on the telescope drive base. An adjustable brightness red LED in the fork arm casts a soft red glow onto the accessory tray in the base to make it easier to select a different eyepiece while observing.\u003c\/p\u003e\n\u003cp\u003eIf you're interested in astroimaging, the 6\" NexStar Evolution 6 is an excellent and very affordable way to get started. It's the only fork-mounted telescope in its price range that offers precision worm gears, along with improved motors, for precise speed control and low periodic error. With the NexStar Evolution's good tracking accuracy, you can capture images of deep-sky objects like the Orion Nebula by simply attaching your DSLR camera. As you progress in the hobby of astroimaging, you can add an optional wedge for longer exposures to bring out faint and hidden details in your astrophotos.\u003c\/p\u003e\n\u003cp\u003eCelestron's time-tested Schmidt-Cassegrain optics and industry-standard StarBright XLT optical coatings give you the bright, sharp views Celestron is famous for -

At 203mm (8”) f\/10, it’s the same C8 optical tube that has been the most popular SCT in production for decades, now integrated into Celestron’s latest mount platform: built-in LiFePO4 battery, onboard WiFi, and the NexStar+ GoTo computer. At 40.6 pounds total kit weight, it’s a one-person setup that a serious observer can carry to a dark site, set up in under 20 minutes, and trust to track accurately through a full night.\u003c\/p\u003e\n\u003cp class=\"p2\"\u003eThe C8 occupies a particular position in the SCT world. It has more accessories designed for it than any other telescope alive. Star diagonals, focal reducers, barlows, camera adapters, off-axis guiders, dew shields, and Hyperstar\/Fastar f\/2 imaging systems — the C8’s 2” rear cell thread and CG-5 dovetail interface are supported by more third-party products than any competing design. That ecosystem doesn’t exist for newer telescopes of comparable aperture, and it adds real value over the life of ownership.\u003c\/p\u003e\n\u003cp class=\"p2\"\u003eThe Evolution mount is well matched to the C8. The 13-pound optical tube is squarely in the design envelope for the single-arm fork — vibration settles quickly, zenith clearance is adequate with a 2” diagonal, and the tracking accuracy is sufficient for visual observing and short-exposure imaging. The 8” is not at the edge of the mount’s capability the way the 9.25” is.

At 51x with the 40mm eyepiece, you have slightly under 1° of true field — enough to take in most deep sky objects as complete fields. At 156x with the 13mm, Saturn’s Cassini Division resolves solidly in average suburban seeing, Jupiter shows four or five distinct cloud features including the Great Red Spot when it transits, and the lunar terminator at high magnification is an exercise in geological imagination.\u003c\/p\u003e\n\u003cp class=\"p7\"\u003eFor deep sky objects, 203mm opens up the NGC catalog in a meaningful way. M13 in Hercules begins to resolve stars across the core at 200x. The Virgo Cluster reveals NGC 4438, 4435, and the surrounding population of galaxies. Stephan’s Quintet shows faint at 200x but is definitively present. Small planetary nebulae like NGC 7662 (Blue Snowball) and NGC 7009 (Saturn Nebula) show structural detail. The magnitude limit of 14.0 reaches well into the fainter NGCs under dark skies.\u003c\/p\u003e\n\u003cp class=\"p7\"\u003eThe C8’s sweet spot is the observer who wants to do both: planets one night, deep sky the next. The 2032mm focal length is long enough for planetary work and, with a 0.63x focal reducer, becomes 1280mm f\/6.3 — a genuine deep sky imaging focal length with the same optical tube. That flexibility is one of the key reasons the C8 has remained the most popular telescope of its type for over 50 years.\u003c\/p\u003e\n\u003cp class=\"p9\"\u003e\u003cb\u003eWhat Cloudy Nights Members Say\u003c\/b\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"p7\"\u003e“I’ve owned a C8 in some form for 20 years. The Evolution version is the best integrated package it’s ever come in. The battery is a legitimate quality-of-life upgrade — I set up in my backyard without thinking about power, and I travel to star parties without a gel-cell. The tracking is the same C8 tracking I’ve always known.”\u003c\/p\u003e\n\u003cp class=\"p7\"\u003e“For the intermediate observer ready to step up from a small scope, the Evolution 8 is the natural destination. You get real aperture, a usable GoTo system, and a tube that does what the community says it does. The C8 has a 50-year track record for a reason.”\u003c\/p\u003e\n\u003cp class=\"p7\"\u003e“The mount is well matched to the C8. Vibrations settle in a second or two. I’ve used it with a 2-inch diagonal at all elevations without clearance problems. The 9.25 was always a little too big for this fork arm. The C8 is right where it should be.”\u003c\/p\u003e\n\u003cp class=\"p9\"\u003e\u003cb\u003eObserving Tip\u003c\/b\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"p7\"\u003eBudget 40–45 minutes for cool-down when moving the C8 from a warm interior to a cold night. The 8-inch corrector plate holds thermal mass longer than you’d expect, and planetary images will noticeably improve after the tube has equilibrated. To speed this up, remove the rear cap while cooling — air circulation through the tube from back to front reduces thermal settling time. If you’re doing a pure planetary session, use a 1.25” eyepiece path rather than a 2” diagonal to minimize the length of the back-focus train. For the best results at high magnification, wait for the image of a star to settle to a steady, sharp point before calling the seeing poor — the first 10 minutes after full cool-down often reveal significantly better seeing than the initial view suggests.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003eFinal Thoughts\u003c\/b\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"p2\"\u003eThe C8 is not a compromise. After 50 years of continuous production, its optics, its accessories, and its reputation are fully developed. The Evolution mount was designed around this optical tube — the balance is right, the stability is right, and the accessory ecosystem that grew up around the C8 over five decades is available to you immediately. If you’re comparing the Evolution 8” to something more expensive, the question worth asking is: how often will you actually observe?

The 9.25” gathers 34% more light and resolves more detail in principle, but it sits at the upper limit of what the single-arm fork handles comfortably. The C8 is comfortably within the mount’s design range, which means better stability and faster vibration damping. The net high-power observing experience — where seeing is usually the limiting factor — often favors the well-mounted 8” over the larger 9.25”. For strictly aperture-limited work (very faint objects, maximum resolution on tight doubles), the 9.25” has a real edge.\u003c\/p\u003e\n\u003cp class=\"p7\"\u003e\u003cb\u003eCan I use the C8 for astrophotography without a wedge? — \u003c\/b\u003eFor planetary and lunar imaging — yes, no wedge needed. The Alt-Az tracking handles the short exposures that planetary cameras use. For long-exposure deep sky work, an equatorial wedge is required to enable the EQ tracking modes and prevent field rotation. With the wedge and a guiding setup, exposures of 1–2 minutes per frame are practical. The Hyperstar\/Fastar f\/2 conversion enables much shorter exposures in Alt-Az mode, which partially sidesteps the field rotation issue for wide-field targets.\u003c\/p\u003e\n\u003cp class=\"p7\"\u003e\u003cb\u003eHow does the NexStar Evolution 8” compare to the NexStar 8SE? — \u003c\/b\u003eBoth use the C8 optical tube with StarBright XLT coatings. The Evolution 8 adds the built-in LiFePO4 battery (no external power needed), integrated WiFi (SkyPortal app control), and a manual clutch on the fork arm. The SE is a solid scope at a lower price point. The Evolution package is worth the upgrade if you value the battery convenience, app control, and improved stability.\u003c\/p\u003e\n\u003cp class=\"p7\"\u003e\u003cb\u003eDoes the CG-5 dovetail on the C8 work with other mounts? — \u003c\/b\u003eYes. The CG-5 dovetail bar is a standard Celestron format compatible with CG-5, AVX, CGX, and other saddle plates that accept the CG-5 standard. The C8 optical tube can be moved to an equatorial mount later if your imaging ambitions grow beyond what the single-arm fork provides — the OTA investment is not locked to this mount.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable style=\"width: 100%;

Paired with the Evolution mount’s integrated technology — a built-in lithium-iron phosphate battery, onboard WiFi, and the NexStar+ GoTo computer — it’s a capable all-in-one setup that doesn’t require an extension cord or an external power tank to work in the field.\u003c\/p\u003e\n\u003cp\u003eFor visual observing, the mount handles the load without difficulty — GoTo tracking is smooth, and the brass worm gears hold their accuracy. Where the single-arm fork shows its limits is in damping time after tapping the focuser, in wind, or when a heavy 2” accessory is attached. Near zenith with a 2” star diagonal, clearance between the focuser and the mount base is tight. \u003c\/p\u003e\n\u003cp\u003eThe step up from the 8” Evolution is real: 34% more light-collecting area, 16% more linear resolving power, a Dawes limit of 0.49 arc seconds versus 0.57, and 1,127x light-gathering advantage over the unaided eye. You see the difference on tight double stars, globular cluster resolution, the ring structure of planetary nebulae, and galaxy surface brightness.

The C9.25 optical tube is Fastar compatible, meaning you can install the optional Hyperstar adapter to convert the scope to f\/2 for ultra-fast wide-field imaging — a completely different operating mode from the standard f\/10 visual configuration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-In LiFePO4 Battery\u003c\/strong\u003e — A 9-cell 6V 4.5Ah lithium-iron phosphate pack is integrated into the mount head with no external battery tank required. Celestron rates it for up to 10 continuous hours of GoTo tracking under normal conditions. Real-world sessions at moderate temperatures confirm 8–10 hours of routine use. It recharges from the included AC adapter, from a 12V vehicle outlet, or via USB.

Connect a smartphone or tablet, open the SkyPortal app, and you have GoTo control, real-time scope status, and access to a 120,000-object catalog — without pulling out the hand controller. SkyPortal is free on iOS and Android.

The accessory tray locks the spread of the legs and holds eyepieces off the wet ground. The CG-5 saddle plate on the mount head accepts the CG-5 dovetail on the C9.25 OTA and is compatible with other CG-5-standard optical tubes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eUnder the Night Sky\u003c\/h2\u003e\n\u003cp\u003eAt 59x with the included 40mm eyepiece, the 9.25” SCT provides about 1° of true field — wide enough to frame the Orion Nebula in its full context, sweep along the Virgo galaxy chain, or show the Beehive Cluster with room to spare. The 13mm eyepiece at 180x is where planetary detail starts to emerge: Cassini’s Division in Saturn’s rings, cloud belt structure on Jupiter, polar ice on Mars at opposition, and the crescent phase of Venus.\u003c\/p\u003e\n\u003cp\u003eBump to 250x–350x in good seeing, and the 9.25” aperture starts to distinguish itself from the 8”. M13 in Hercules resolves to individual stars across most of the core. The Ring Nebula (M57) shows a distinct donut shape with a darker center. NGC 4565, the edge-on galaxy in Coma Berenices, shows a clean dark lane across the nucleus at 200x. Tight double stars like Porrima reach the edge of resolution, compared to the 8” which may or may not split it cleanly depending on conditions.\u003c\/p\u003e\n\u003cp\u003eThe 2350mm focal length is excellent for planets but can feel limiting on large nebulae. For objects like the North America Nebula or M31, the 40mm eyepiece gives you the widest field this scope will produce. For strictly visual wide-field work, a shorter-focal-length instrument may complement the 9.25” more than replace it.\u003c\/p\u003e\n\u003ch2\u003eWhat Cloudy Nights Members Say\u003c\/h2\u003e\n\u003cp\u003e“The optics on the C9.25 are exceptional — tight stars right to the edge with the right eyepiece, and planetary detail that made me retire my 8-inch. The mount tracks well enough for high-power observing. I use it strictly visual and haven’t hit any of the clearance issues people mention, because I just never go to zenith with a 2-inch diagonal.”\u003c\/p\u003e\n\u003cp\u003e“I had an 8SE for years and the 9.25 Evolution is a meaningful upgrade. That extra inch and a quarter makes a difference on globulars and small planetary nebulae. The built-in battery is genuinely useful — I don’t miss hauling a gel-cell to my dark site.”\u003c\/p\u003e\n\u003cp\u003e“For what I do — visual observing from the backyard, mostly planets and bright showpiece objects — this scope is excellent. I went in knowing the single-arm fork has limits compared to the CPC. Those limits haven’t been a problem for me. People who want to image long-exposure deep sky should look at the CPC or an EQ mount.”\u003c\/p\u003e\n\u003ch2\u003eObserving Tip\u003c\/h2\u003e\n\u003cp\u003eThe C9.25 corrector plate is larger than the C8 and holds heat longer — budget 45–60 minutes for cool-down before pushing to high powers on planets, and you’ll be rewarded with steadier images. A shroud or dew heater on the corrector prevents fogging on humid nights. If you’re using a 2” diagonal, be aware that approaching zenith puts the diagonal body close to the mount base. Keep objects at least 10–15° below zenith, or switch to a 1.25” diagonal for high-altitude targets.\u003c\/p\u003e\n\u003ch2\u003eFinal Thoughts\u003c\/h2\u003e\n\u003cp\u003eThe NexStar Evolution 9.25” is a serious instrument in a genuinely portable package. Its honest character is this: more aperture than the C8, less stability than the CPC, better portability than either. For a visual observer who wants the most aperture the Evolution fork mount can comfortably carry — and who understands the single-arm fork’s limitations going in — this is the right telescope. For everyone else, the Evolution 8” does 90% of what this scope does at less cost, less weight, and with a mount that was sized specifically for the OTA it carries. Know which observer you are before you buy.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWhat’s the practical difference between the Evolution 9.25” and the Evolution 8”? — \u003c\/strong\u003eThe 9.25” gathers 34% more light and resolves 16% more detail — the difference is visible on tight double stars, globular cluster resolution, and small planetary nebulae. The tradeoff is weight: the C9.25 OTA is 20 lbs versus the C8’s 14 lbs, which means more vibration settling time and tighter zenith clearance with a 2” diagonal. For strictly visual observing, the extra aperture is worth it. For maximum portability and stability, the 8” Evolution has the edge.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the built-in battery actually last 10 hours? — \u003c\/strong\u003eCelestron’s 10-hour rating holds in normal temperatures with regular GoTo slewing. In practice, 8–10 hours is typical. Cold weather (below freezing) reduces that to roughly 6–8 hours. The battery charges fully in 6–8 hours from the included AC adapter, and can also charge from a 12V vehicle outlet or USB source. For multi-night star parties, a charged power bank or vehicle outlet between sessions keeps it topped off.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the NexStar Evolution 9.25” good for astrophotography? — \u003c\/strong\u003eFor planetary and lunar imaging, yes — the 2350mm focal length at f\/10 is ideal for high-resolution planetary work, and the tracking is accurate enough for the short exposures a planetary camera uses. For long-exposure deep sky imaging, pair it with an equatorial wedge to enable EQ tracking mode, and plan to guide. The Fastar\/Hyperstar conversion to f\/2 enables wide-field imaging with short exposures. For very serious deep sky imaging, a dedicated EQ mount like the Advanced VX will outperform the single-arm fork.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this scope without the hand controller, using just the app? — \u003c\/strong\u003eYes. The SkyPortal app connects directly to the mount’s WiFi hotspot and provides full GoTo control and a 120,000-object catalog. You’ll still need to run an alignment procedure, but you can do the entire session from the app. The hand controller is always there as a backup, and some observers prefer it for quick star-to-star slewing.

The CG-5 dovetail bar is a standard Celestron format compatible with the CG-5, AVX, CGX, and other saddle plates that accept the CG-5 standard.

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

The AT115EDT is a 115mm f\/7 ED triplet that exists to deliver that moment, night after night, without costing what a premium APO costs. It won't do everything. It won't hunt down magnitude-14 galaxies or replace a 12-inch Dob for faint fuzzies. But for planets, the Moon, double stars, bright deep-sky, and serious astrophotography, it does what refractors do better than any other optical design — and at 115mm, it gathers over 27% more light than the 102mm refractors it often sits next to on the shelf.\u003c\/p\u003e\n\u003ch3\u003eThe Optics\u003c\/h3\u003e\n\u003cp\u003eTriplet apochromatic with an FK-61 ED center element — that's Schott's FPL-51 equivalent, slow-polished for smooth surfaces and low scattered light. Three lens elements, fully multicoated on all air-to-glass surfaces. The result is what refractor people are actually paying for: high contrast, pinpoint stars, and virtually no chromatic aberration at the focal plane. At 805mm focal length and f\/7, the AT115EDT is fast enough for efficient imaging but slow enough to be forgiving on eyepiece quality. The internal light baffles are knife-edge design, and the lens edges are blackened — both details that contribute to the deep, dark sky backgrounds this scope is known for.  Ed Ting's review on Cloudy Nights noted the AT115EDT delivered excellent views of planets, the Moon, and double stars — and called it a strong recommendation. \u003c\/p\u003e\n\u003ch3\u003eThe Focuser\u003c\/h3\u003e\n\u003cp\u003eThis is where the AT115EDT quietly separates itself from competitors in its price class. The 3.2\" dual-speed rack-and-pinion focuser has two coarse focusing knobs and a concentric 10:1 fine-focus microknob. Ninety-five millimeters of travel with a millimeter scale on the drawtube for repeatable photographic focus. A lock knob underneath holds your position. One Cloudy Nights member tested the focuser by loading a 2\" diagonal, a 28mm UWA eyepiece, and an actual brick onto the drawtube — 8.2 pounds total. He could position the focuser anywhere and it held, with the fine-focus knob still raising and lowering the load with precision. You will not need to do this. But knowing you could says something about the mechanical quality.\u003c\/p\u003e\n\u003cp\u003eThe focuser rotates a full 360° for camera framing — loosen the knob on top, rotate to your desired angle, tighten. The 2\" eyepiece holder includes a built-in camera angle adjuster for fine compositional tweaks without disturbing the heavier focuser body. Both 2\" and 1.25\" holders use compression rings, not thumbscrews, so your eyepiece and diagonal barrels stay unmarred. These are features that show up on scopes costing significantly more. On the AT115EDT, they're standard.\u003c\/p\u003e\n\u003ch3\u003eThe Tube and Rings\u003c\/h3\u003e\n\u003cp\u003eThe 114mm diameter optical tube is finished in white with grey anodized trim — clean, professional, durable. At 27.25\" long (32.4\" with the retractable dew shield extended), it's compact enough for travel and short enough to balance well on a mid-weight equatorial mount. Total weight with rings, handle, and Losmandy dovetail: 15.25 pounds. \u003c\/p\u003e\n\u003cp\u003eThe dual split hinged CNC tube rings are lined with white felt (not black, which can stain white tubes over time). A Losmandy-style dovetail bolts to the rings with a carry handle on top. Two Vixen-style finderscope shoes are mounted on the tube. A slip-on metal dust cap protects the objective, and a dust seal covers the eyepiece holder. The scope also has full collimation capability — three pairs of collimation screws sit under the silver collar at the back of the dew shield.\u003c\/p\u003e\n\u003ch3\u003eAstrophotography\u003c\/h3\u003e\n\u003cp\u003eAt f\/7 with 805mm of focal length, the AT115EDT is a serious imaging platform. The focal ratio is fast enough for reasonable exposure times on deep-sky targets but slow enough that stars stay tight across the field without a corrector for visual work. For imaging, pair it with the dedicated 0.8x reducer\/flattener to drop to f\/5.6 and 644mm — a faster, wider-field imaging configuration with a flat, corrected field across APS-C and full-frame sensors. A 1x field flattener is also available for full focal length imaging with flat stars to the corners.\u003c\/p\u003e\n\u003cp\u003eThe camera angle adjuster, compression rings, and rotatable focuser make photographic setup faster and more precise than scopes that lack these features. The focuser's 95mm of travel accommodates virtually any diagonal, camera, and accessory combination without running out of in-focus or needing extension tubes — a versatility that owners consistently praise.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAstro-Tech AT115EDT 115mm f\/7 ED triplet refractor OTA\u003c\/li\u003e\n\u003cli\u003eDual split hinged CNC tube rings with white felt lining\u003c\/li\u003e\n\u003cli\u003eLosmandy-style dovetail plate with carry handle\u003c\/li\u003e\n\u003cli\u003e2\" eyepiece holder with compression ring and camera angle adjuster\u003c\/li\u003e\n\u003cli\u003e1.25\" adapter with compression ring\u003c\/li\u003e\n\u003cli\u003eRetractable dew shield\u003c\/li\u003e\n\u003cli\u003eMetal dust cap and eyepiece holder dust seal\u003c\/li\u003e\n\u003cli\u003eSoft-sided heavy-duty nylon carry case with foam cutouts for 7 accessories\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e115mm (4.53\") FK-61 ED triplet optics\u003c\/strong\u003e — Over 27% more light-gathering than a 102mm refractor.

Push to 200x on the best evenings and the belts begin to show scalloping and rifts. Four or five belts become visible at the limits of the seeing. The Galilean moons show disks, not points. The contrast of a well-corrected triplet makes the difference here — the belts are sharply defined against the zones, with none of the scattered light that softens the view in lesser optics.\u003c\/p\u003e\n\u003cp\u003eSaturn at 160x shows Cassini's Division as a clean dark gap, not a thin line. The shadow of the globe on the rings is crisp. The crepe ring is visible against the globe on transparent nights. Titan is obvious; two or three fainter moons show up with averted vision.\u003c\/p\u003e\n\u003cp\u003eThe Moon is where refractors earn their keep, and the AT115EDT delivers. At 200x, the terminator is alive with shadow detail — crater walls catching the first light, rilles threading across mare floors, the Straight Wall casting its knife-edge shadow. You're seeing the kind of sharpness and contrast that made refractors the instrument of choice for lunar and planetary observers for four centuries.\u003c\/p\u003e\n\u003cp\u003eDouble stars are a refractor specialty. Albireo splits into gold and blue at any magnification. Epsilon Lyrae — the Double Double — cleanly resolves all four components at 200x. At 1.01 arc seconds of resolution, the AT115EDT handles tight pairs that would challenge many 4-inch scopes.\u003c\/p\u003e\n\u003cp\u003eDeep-sky is real but bounded by aperture. The Ring Nebula (M57) shows its annular shape clearly. M13 resolves to individual stars across the face. The Andromeda Galaxy stretches across the field at low power with dark lanes visible on a good night. The Double Cluster in Perseus is a showpiece — dozens of stars scattered across the field with a clarity that only a refractor delivers. What you won't get: the faintest galaxies, the dimmest planetary nebulae, the deep structure in large faint objects. For that, supplement with a larger reflector. The AT115EDT is not trying to be everything. It's trying to be excellent at what refractors do best.\u003c\/p\u003e\n\u003ch3\u003eCommunity Says\u003c\/h3\u003e\n\u003cp\u003e\"It's difficult for me to consider another refractor that offers this much value.

An HEQ5\/EQ5-class mount will carry it for visual observing, but for imaging — especially with a camera, guidescope, and accessories — you'll want an EQ6 or Losmandy G11 class mount for stability. Match the mount to the job: if you're visual-only, the lighter mount saves setup time and backache. If you're imaging, don't compromise on mount capacity. The scope deserves a steady platform.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow does this compare to a 102mm ED refractor?\u003c\/strong\u003e\u003cbr\u003eThe AT115EDT gathers over 27% more light than a 102mm — that's a meaningful jump. You'll see fainter stars, resolve tighter doubles, and collect more signal in less time when imaging. At f\/7, the AT115EDT is also faster than most 102mm f\/7.8 or f\/8 doublets, which means shorter exposures for astrophotography. The dual-speed 3.2\" focuser, compression rings, and camera angle adjuster are features that many 102mm scopes at the same price don't include.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the FK-61 glass as good as FPL-53?\u003c\/strong\u003e\u003cbr\u003eDifferent, not lesser — for most uses. FK-61 (FPL-51 equivalent) in a triplet design provides excellent chromatic correction. You might see a faint violet halo on bright stars at high power that an FPL-53 or FCD-100 scope would eliminate. In imaging, it's a non-issue with narrowband or modern broadband filters. In visual use, most owners don't notice it under normal conditions. If absolute chromatic perfection is your priority, look at the AT150EDL (FCD-100 glass) or the AT72EDII (FPL-53 glass, smaller aperture). For the vast majority of observers, the FK-61 triplet gives you more aperture for your money — and more aperture means more resolution, more light, and more capability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat mount do I need?\u003c\/strong\u003e\u003cbr\u003eFor visual observing: an HEQ5-class equatorial mount or a solid alt-az mount handles the AT115EDT well. Total payload with diagonal and eyepiece is around 17 pounds. For astrophotography: step up to an EQ6 or Losmandy G11 class mount to get the stability you need for guided long exposures. The Losmandy dovetail is included, so you're ready for Losmandy-compatible saddles out of the box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat do I need for astrophotography with this scope?\u003c\/strong\u003e\u003cbr\u003eAt minimum: the scope, a sturdy equatorial mount with tracking, a camera (DSLR\/mirrorless or dedicated astronomy camera), and a field flattener or reducer\/flattener. The AT115EDT's 0.8x reducer\/flattener takes you to f\/5.6 and 644mm — faster and wider for deep-sky imaging. The 1x flattener keeps you at f\/7 and 805mm with flat stars to the corners. Dedicated CMOS and CCD astronomy cameras connect directly via 48mm T-threads; DSLR and mirrorless cameras need a T-ring for your specific mount (sold separately).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this OTA only? What else do I need?\u003c\/strong\u003e\u003cbr\u003eYes — no mount, eyepieces, diagonal, or finder are included. Plan on a 2\" star diagonal, a set of eyepieces (a 25mm for wide field, a 10mm for medium power, and a 4–5mm for planetary is a good starting trio), and a finderscope or red dot sight. If you're new to refractors, budget for the complete system. A telescope like the AT115EDT deserves quality accessories to match its optics.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it come with a case?\u003c\/strong\u003e\u003cbr\u003eYes — a soft-sided heavy-duty nylon carry case with paper pockets in the lid and foam cutouts for 7 accessories.

It's 115mm of triplet APO with a focuser that holds a brick, optics that compare favorably to scopes at significantly higher prices, and a package of features — compression rings, camera angle adjuster, Losmandy dovetail, carry case — that most competitors charge extra for or skip entirely. It won't replace a 10-inch Dob for hunting the faintest deep-sky objects. It will show you planets, the Moon, double stars, and bright deep-sky with a clarity and contrast that no reflector at any price can match.

The AT130EDT combines a 130mm f\/7 triplet objective, a heavy-duty 3.2-inch rack-and-pinion focuser, and a mechanical package built for serious visual observing and astrophotography. It's large enough to resolve fine planetary detail, gather meaningful light from distant galaxies, and support full imaging trains without compromise.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe AT130EDT has earned its reputation through years of use by visual observers and astrophotographers alike. The optical design, focuser, and mechanical package work together as a complete system, making it one of the most versatile refractors Astro-Tech has ever offered.\u003c\/p\u003e\n\u003ch3\u003eThe Optical Design\u003c\/h3\u003e\n\u003cp\u003eThe AT130EDT is a three-element FK-61 ED triplet. The front objective is an apochromatic triplet with one ED (Extra Dispersed) element for color correction. All surfaces carry fully multicoated antireflection coatings, optimized for the specific glass types. The interior has multiple knife-edge baffles plus micro baffles in the drawtube, and the lens edges are blackened to control stray light. \u003cmeta charset=\"utf-8\"\u003eFK-61 is generally considered comparable in performance to Ohara FPL-51 when used in similar optical designs.\u003c\/p\u003e\n\u003cp\u003eThe mechanical assembly inside the tube is tight. FK-61 expansion from ambient temperature change is controlled by a precision cell that maintains optical alignment. The objective is sealed — dust, moisture, and temperature swings don't degrade performance over time. In the field, a 130mm triplet needs cool-down time like any refractor, but the thermal mass is manageable — expect 30 to 45 minutes before optics stabilize on a cool night. \u003cmeta charset=\"utf-8\"\u003eLike most 130mm triplets, the AT130EDT benefits from 30–45 minutes of thermal stabilization when moving from a warm environment into significantly cooler night air. The scope rewards both.\u003c\/p\u003e\n\u003ch3\u003eThe 3.2\" Rack-and-Pinion Focuser\u003c\/h3\u003e\n\u003cp\u003eThe AT130EDT focuser is a 3.2-inch (81mm) dual-speed rack-and-pinion mechanism with a concentric 10:1 fine-focus knob — the coarse knob and the fine knob are concentric on the same axis, so you can move between coarse and fine without moving your hand. Travel is smooth and repeatable across the full 85mm range. The drawtube itself is marked in millimeter increments for recording focus positions and for matching backfocus on cameras.\u003c\/p\u003e\n\u003cp\u003eThe focuser's 3.2-inch drawtube accepts a large variety of connection systems and handles heavy imaging loads without flexure or image shift. The current production focuser terminates in M92 threads, which connect directly to the AT130EDTRFv3 reducer\/flattener or to a T-ring for standard DSLR\/mirrorless camera work. Older AT130EDT models (pre-2023) used a 2.5-inch focuser with M63 threads — if you're matching a reducer to an older scope, you need the ATREDT30V2, not the newer v3. The two are not interchangeable.\u003c\/p\u003e\n\u003cp\u003eBuilt into the focuser is a camera angle adjuster — a rotating collar that lets you frame your target in landscape, portrait, or any angle between without disassembling the imaging train. A large locking knob keeps rotation steady. This is the feature that saves imaging sessions on nights when framing matters or when you're working in tight spaces with multiple cameras on a multi-scope setup.\u003c\/p\u003e\n\u003ch3\u003eBuilt for the Field\u003c\/h3\u003e\n\u003cp\u003eThe AT130EDT weighs 18.5 pounds with the optical tube and its internal cell, plus mounting rings. With dovetail and carry handle, you're moving about 22 pounds — heavy enough to be a serious optical system, light enough that a single person carries it without strain from car to telescope pad. The scope is 27.5 inches long retracted, and 31 inches with the dew shield extended. \u003c\/p\u003e\n\u003cp\u003eThe mounting system is built to match. Hinged split tube rings with felt linings let you remove and reposition the scope without tools — a practical advantage for equipment swaps or for repositioning the tube during a long session to reach targets at difficult azimuths. The Losmandy-style dovetail plate is rigid and well-indexed, and it's compatible with most saddle plates in that size class. The carry handle has multiple functions: you lift the scope with it, you store accessories and eyepieces in it, and you can mount a guide scope or off-axis guider to it.\u003c\/p\u003e\n\u003cp\u003eThe retractable dew shield extends 4 inches from the objective cell and stores flush against the tube when retracted. In humid conditions, it's a genuine advantage — dew control is easier, and the shield also reduces stray light from overhead sources. For transport, it stows into less than 2 inches of additional length.\u003c\/p\u003e\n\u003cp\u003eThe included nylon carrying case is a first-class protection layer for the optics tube. It's designed with padding on the interior, latches that hold firm, and handles for single-person carry. From backyard to dark sky site, this case has earned its place in the box.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAstro-Tech AT130EDT 130mm f\/7 FK-61 ED triplet refractor OTA\u003c\/li\u003e\n\u003cli\u003eHinged split tube rings (felt-lined) with Losmandy-style dovetail plate\u003c\/li\u003e\n\u003cli\u003eCarry handle with mounting points for accessories\u003c\/li\u003e\n\u003cli\u003e2\" accessory holder with non-marring brass compression ring\u003c\/li\u003e\n\u003cli\u003e1.25\" accessory adapter with non-marring brass compression ring\u003c\/li\u003e\n\u003cli\u003eRetractable self-storing dew shield\u003c\/li\u003e\n\u003cli\u003eNylon carrying case\u003c\/li\u003e\n\u003cli\u003eSlip-on metal dust cap\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e130mm f\/7 FK-61 ED triplet with three-element design.\u003c\/strong\u003e Apochromatic triplet correction brings all three primary colors to the focal plane, eliminating false color.

The Dawes diffraction limit is 0.89 arc seconds. The visual limiting magnitude is 13.2. In good conditions at a reasonably dark site, you're finding galaxies that challenge smaller scopes and planets that reward high magnification.\u003c\/p\u003e\n\u003cp\u003eOn the Moon, the AT130EDT shows terraced crater walls, central peaks, and fine rille structure across the entire disc. The terminator reveals texture — Copernicus at 150× shows its terraced ramparts clearly, the Straight Wall is a clean shadow line, and Aristarchus glows like a torch. The lack of false color means the Moon stays crisp and bright-looking even at high power. A 4mm eyepiece at 228× on the Moon is a memorable session — planetary detail you don't forget.\u003c\/p\u003e\n\u003cp\u003ePlanets respond well to 130mm of aperture in this focal ratio. Mars shows polar caps, surface markings, and subtle cloud structure when the opposition position is favorable. Jupiter's Great Red Spot is prominent, and the Cassini Division on Saturn is visible at moderate power under decent seeing. \u003cmeta charset=\"utf-8\"\u003eVenus displays clean crescent phases with excellent color correction. The triplet design keeps the disc contrast high — no magenta or cyan haloes diluting the view.\u003c\/p\u003e\n\u003cp\u003eDouble stars separate cleanly. At 0.89 arc seconds, the AT130EDT splits tight optical pairs that smaller scopes need dark adaptation or averted vision to resolve. Castor resolves at moderate power (5.6 arc seconds). Epsilon Lyrae separates at 150×. Rigel shows its 7th-magnitude companion 9.4 arc seconds away — a test of true contrast, not just resolution. Albireo at low power is a striking color-contrast pair with no false color to mar the view.\u003c\/p\u003e\n\u003cp\u003eDeep sky through a triplet refractor is a different experience than through a reflector or a doublet. The flat field and the high contrast from the triplet design mean you see nebulae with good definition and clusters with sharp stars to the edge of the field. M42 (Orion Nebula) shows fine internal structure — not just the main nebular cloud, but the Running Man nebulosity and the background emission. The Rosette Nebula appears as a full ring structure at low power on dark nights. M31 (Andromeda) spans an impressive width, with dust lane detail visible in good conditions. Messier open clusters — M13, M35, M36, M37, M38 — pop with detail. The lack of a central obstruction means stars appear as clean points rather than diffraction-ring-crossed discs.\u003c\/p\u003e\n\u003ch3\u003eCommunity Says\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e\"The AT130EDT has been my workhorse for two years.

Spend the early part of an evening exploring large nebulae and open clusters at lower power, then move to planets, double stars, and globular clusters as the telescope reaches thermal equilibrium. A 130mm triplet rewards observers who use the full range of what the aperture can offer.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the AT130EDT compare to the AT125EDL doublet?\u003c\/strong\u003e\u003cbr\u003eDifferent design philosophies at similar apertures and focal length. The AT130EDT is a 130mm f\/7 FK-61 triplet with a 3.2-inch focuser and Losmandy dovetail. The AT125EDL is a 125mm f\/7.8 FCD-100 (premium glass) doublet with a 2.5-inch focuser and Vixen dovetail. The triplet design has one advantage in color correction — all three primary colors are brought into coincidence at the focal plane, which shows as crisper contrast on planets. The doublet at FCD-100 quality has a smaller thermal mass and cools faster (25-30 minutes vs. 35-45 minutes for the triplet). The triplet has more aperture and a larger focuser for heavier imaging trains. The doublet has more premium glass and fits lighter mounts. Both are excellent scopes. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich reducer or flattener do I need?\u003c\/strong\u003e\u003cbr\u003eIt depends on your focuser version. If your AT130EDT has the 3.2-inch focuser with M92 threads (current production, 2023 onward), you need the AT130EDTRFv3 reducer\/flattener. If you have an older AT130EDT with the 2.5-inch focuser and M63 threads, you need the ATREDT30V2. They have different thread sizes and are not interchangeable. Check your focuser drawtube carefully — the thread size is marked. The field flattener option is the AT130EDTFFv3 (1×), which is a flattening optic only, not a focal-length changer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat mount does this scope need?\u003c\/strong\u003e\u003cbr\u003eThe AT130EDT at roughly 22 pounds (with rings and dovetail) needs a mount rated for at least 35 pounds of payload for astrophotography — you need headroom above the tube weight to handle cameras, off-axis guiders, filter wheels, and dew heaters without the mount straining. For visual use, an equatorial mount rated for 30+ pounds works well. The Losmandy dovetail suggests compatibility with heavy-duty mounts — a ZWO AM5, an iOptron CEM60, a Skywatcher HEQ6, or an older Losmandy mount in that weight class. A lighter mount will work for visual observation but will flex noticeably under a heavy imaging camera. Plan on a mount that is overkill for the visual package — you'll thank yourself when you load cameras.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this good for astrophotography?\u003c\/strong\u003e\u003cbr\u003eThe AT130EDT is one of the most popular imaging refractors in the Astro-Tech line — it shows up regularly in astrophotography forums and imaging equipment discussions because it delivers. The 3.2-inch focuser handles heavy camera systems without flexure. The rotatable drawtube and camera angle adjuster simplify field rotation and framing. At 910mm f\/7 on a full-frame or APS-C sensor, you frame larger nebulae and galaxies well. With a reducer, you drop to 728mm f\/5.6 for faster exposures and a wider field. The triplet design is favorable for imaging — color correction is flat across the field, which means less post-processing correction needed. Pair it with a quality mount, a guide scope, and a good camera, and you have a capable imaging platform.\u003c\/p\u003e\n\u003ch3\u003eOptional Accessories\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAT130EDTRFv3 0.8× Reducer\/Flattener (M92 threads):\u003c\/strong\u003e Converts the AT130EDT from 910mm f\/7 to 728mm f\/5.6 with a corrected flat field.

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.

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

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

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 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. Even without a clear view of Polaris, the EQ Pro can be polar aligned using our SynScan hand controller.

Years of owner reviews later, the AT60ED has earned that reputation many times over. This is a 60mm f\/6 ED doublet with FPL-53 and Lanthanum glass — the same premium ED optics that define refractor performance — packed into a scope small enough to fit a backpack. It works as a wide-field visual scope, a capable travel refractor, a guide scope, or a small-chip astrophotography platform. It does all four well, and none of them compromise.\u003c\/p\u003e\n\u003cp\u003eThe key is the glass. FPL-53 is Ohara's premium ED element, paired here with a Lanthanum element to deliver virtually zero chromatic aberration at f\/6. The AT60ED's 360mm focal length is fast — fast enough for efficient wide-field imaging, fast enough to show brighter deep-sky objects in impressive fields of view, fast enough that you can gather a surprising amount of light in short exposures. For a scope you can literally carry in one hand, that's serious capability.\u003c\/p\u003e\n\u003cp\u003eThe focuser is a dual-speed 2-inch Rack and Pinion with 10:1 fine focus and a camera angle adjuster. This is the kind of focuser found on much larger scopes. The CAA lets you rotate your camera or guide camera for framing without moving focus. The scope mounts via a finder ring with a 1\/4\"-20 tapped foot — straight onto a photo tripod, or into a standard finder shoe on a larger scope for piggyback work. The retractable dew shield stores flat against the tube for travel. Light, compact, versatile, and with optics that punch far above the aperture.\u003c\/p\u003e\n\u003ch3\u003eThe Optical Design\u003c\/h3\u003e\n\u003cp\u003eFPL-53 glass is Ohara's premium ED element. Paired with a Lanthanum element, it produces a doublet design that delivers near-zero chromatic aberration at this focal ratio. The surfaces are fully multicoated to maximize light transmission and contrast. What this means in practice: bright, sharp star images with virtually no false color, even at moderate magnifications. The 360mm focal length at f\/6 puts the AT60ED in the sweet spot where refractors excel — fast enough to be practical, slow enough to be forgiving on eyepiece quality.\u003c\/p\u003e\n\u003ch3\u003eThe Focuser\u003c\/h3\u003e\n\u003cp\u003eMost 60mm scopes come with a simple focuser. The AT60ED doesn't. The 2-inch dual-speed Rack and Pinion gives you coarse focus on one knob and 10:1 fine focus on a concentric microknob. For visual work at moderate powers, coarse focus is fine. For astrophotography with a camera that weighs more than an eyepiece, or when you're chasing critical focus on a guide star, the 10:1 ratio becomes essential. One user loaded a 2\" diagonal, a wide-field eyepiece, and a camera onto the drawtube — over 3 pounds — and reported the focuser held position without drift.\u003c\/p\u003e\n\u003cp\u003eThe built-in camera angle adjuster lets you rotate your camera or guide camera for framing without disturbing focus. Loosen the adjuster, rotate to your desired angle, tighten. For astrophotography, this saves you from the usual dance of adjusting focus after rotating the camera. For guide scope work, it means you can position your guide camera to find a suitable guide star without refocusing.\u003c\/p\u003e\n\u003ch3\u003eBuilt for the Field\u003c\/h3\u003e\n\u003cp\u003eThis scope was designed for motion — from the car to the dark site, from the backyard to a high-altitude location, from sitting on a photo tripod to riding piggyback on a larger scope. The finder ring with 1\/4\"-20 tapped foot is the key. Any photo tripod, any finder shoe, any mounting bracket with standard photo threads accepts it. No special adapters, no dovetails that only fit one brand of mount, no compromise with existing gear.\u003c\/p\u003e\n\u003cp\u003eAt about 3.25 pounds, the AT60ED is among the lightest refractors in the Astro-Tech lineup — light enough to carry in one hand, ride piggyback on a larger scope, or sit on a sturdy photo tripod. For travel, for driveway astronomy, for throw-it-in-the-car observing, weight matters. This scope goes everywhere.\u003c\/p\u003e\n\u003cp\u003eThe guide scope role is worth its own mention. At 360mm focal length, the AT60ED provides enough image scale for reliable autoguiding with standard guide cameras. The camera angle adjuster means you can position your guide camera without refocusing. Mount it on a finder shoe above your main imaging rig, and you have a compact, capable guide scope that doesn't consume real estate or add weight to your imaging setup. For small to mid-size refractors, the AT60ED serves double duty: when you upgrade to a larger imaging scope, keep it as your guide scope.\u003c\/p\u003e\n\u003cp\u003eThe 1\/4\"-20 mount also accepts standard photo tripod heads — ball heads, geared heads, whatever you prefer. Attach it to a quality photo tripod and you have a wide-field visual scope that sets up in seconds and fits in the car without contention for space.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAstro-Tech AT60ED 60mm f\/6 FPL-53 + Lanthanum ED doublet refractor OTA\u003c\/li\u003e\n\u003cli\u003eFinder ring with 1\/4\"-20 tapped foot\u003c\/li\u003e\n\u003cli\u003e2\" eyepiece holder with compression ring and camera angle adjuster\u003c\/li\u003e\n\u003cli\u003e1.25\" adapter with compression ring\u003c\/li\u003e\n\u003cli\u003eRetractable dew shield\u003c\/li\u003e\n\u003cli\u003eSlip-on metal dust cap\u003c\/li\u003e\n\u003cli\u003eNylon soft carry case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFPL-53 + Lanthanum doublet optics\u003c\/strong\u003e — Ohara's premium ED glass with Lanthanum element.

At 60x with a 6mm eyepiece, the Moon fills the field and the terminator comes alive with shadow detail — crater walls catching the first light, rilles threading across mare floors. The bright craters pop against the dark maria with the contrast that only a well-corrected refractor delivers. At 100x on steady nights, you're seeing sharp, high-contrast lunar features. It's not a 10-inch Dob, but what you see is vivid and real.\u003c\/p\u003e\n\u003cp\u003eJupiter and Saturn reward the AT60ED with surprisingly detailed views. \u003cmeta charset=\"utf-8\"\u003eJupiter reveals the two main equatorial belts and the changing positions of its Galilean moons. Saturn shows its ring system clearly separated from the globe, and under steady skies hints of the Cassini Division become visible. The Moon is especially rewarding, with razor-sharp crater walls and excellent contrast along the terminator. You won't achieve planetary mag-140x performance, but the AT60ED at 100-120x delivers planetary views that make you forget you're looking at a 60mm scope.\u003c\/p\u003e\n\u003cp\u003eDouble stars are a refractor speciality, and the AT60ED shows them well. Albireo splits easily even at low power, gold and blue separated cleanly. Epsilon Lyrae — the Double Double — resolves all four components at 100x. The contrast and sharpness are what refractors are actually for, and the AT60ED doesn't disappoint.\u003c\/p\u003e\n\u003cp\u003eWide-field deep-sky is where the AT60ED shines. At f\/6 with 360mm focal length, a 30mm eyepiece delivers a 3-degree field of view — large enough that you're seeing context, seeing neighborhoods of stars, seeing the Milky Way as a structure rather than scattered points. The Pleiades fill the field with their brightness and arrangement. The Double Cluster in Perseus spans the view with a clarity that only a refractor delivers. The Andromeda Galaxy stretches across the field at low power with dark lanes visible on a good night. M31, M33, the Hyades, the Beehive — all look better through a 60mm f\/6 than through higher-magnification instruments. Wide-field observing rewards aperture and focal ratio over magnification, and the AT60ED has both.\u003c\/p\u003e\n\u003cp\u003ePlanets are limited by aperture — you won't resolve detail on Mars or Saturn that a 6-inch scope shows. Faint galaxies are out of reach. The dimmest planetary nebulae are inaccessible. But everything bright, everything colorful, everything that benefits from pure optical excellence and wide fields of view is fair game. Use the AT60ED for what it's built for, and it delivers.\u003c\/p\u003e\n\u003ch3\u003eCommunity Says\u003c\/h3\u003e\n\u003cp\u003eThe AT60ED has been discussed and dissected on Cloudy Nights for years, often head-to-head against pricier rivals.

The AT72EDII has more aperture — 72mm vs. 60mm — which means 44% more light, higher resolution, and slightly more reach at 432mm vs. 360mm focal length. The AT72EDII comes with two tube rings and a Vixen dovetail (heavier, more capable mounting). The AT60ED uses a simple 1\/4\"-20 foot (lighter, more flexible mounting). Choose the AT60ED for maximum portability and versatility; choose the AT72EDII for more aperture in a still-compact package.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between FPL-53 and FK-61 glass?\u003c\/strong\u003e\u003cbr\u003eFPL-53 is Ohara's premium ED element; FK-61 is Schott's FPL-51 equivalent (also excellent, but a different standard). \u003cmeta charset=\"utf-8\"\u003eFPL-53 generally allows tighter color correction than FK-61 when used in similar optical designs. The AT60ED uses FPL-53. The AT70ED uses FK-61 with a simpler focuser and no CAA. Both are good scopes; the AT60ED is the premium version.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this as a guide scope?\u003c\/strong\u003e\u003cbr\u003eYes — it's an ideal guide scope.
