Meade 14" f/10 LX200-ACF OTA w/UHTC
Meade SKU: 1410-60-01 | Helix SKU: ME14106001
Overview
Advanced Coma-Free LX200 Optical Tube comes with Meade's Ultra-High Transmission Coatings (UTHC), Oversized Low-Expansion Borosilicate Primary Mirror, Schott Borofloat Glass Corrector Plate, Diffraction Limited Optics, Losmandy-style dovetail, and Dust Cover.
The Advanced Coma-Free (ACF) optical system has brought the highest level of optical performance well within the reach of most amateurs. Using the Meade exclusive design, ACF optics achieve aplanatic performance — with a flatter field, reduced astigmatism and eliminated diffractions spikes — equal to Ritchy-Chétien systems, at a fraction of the price. Coupled with Meade’s Ultra- High Transmission Coatings (standard on all LX200-ACF systems), you have the ultimate in premium optics.
All LX200 models feature a primary mirror locking mechanism, which effectively prevents movement of the primary mirror during long exposure astrophotography or observing. Turn the lock knob located just above the telescopes main focus knob and the progressive-tension primary lock completely cancels any residual image shift due to mirror movement during visual, photographic, or imaging applications.
The 14" LX200 Optical Tube Assembly #0410-60-01 has a 3556mm focal length, an f/10 focal ratio, and weighs 57lbs.

Sky-Watcher AZ-EQ5 Mount
Sky-Watcher SKU: S30200 | Helix SKU: CTS30200
Versatile, Lightweight and Astonishingly Accurate
Our AZ-EQ5 hybrid mount epitomizes Sky-Watcher’s commitment to innovation. Part AZ mount, part equatorial, the AZ-EQ5 is Sky-Watcher’s most versatile mount, capable of aligning in either Alt-Az, Equatorial or dual-OTA mode. Thanks to it’s flexibility, the AZ-EQ5 mount is perfect for the beginning astronomer looking to get into astrophotography, the seasoned astrophotography buff or educators passionate about astronomy outreach.
Unlike Any Other Mount on the Market
Unique to Sky-Watcher’s AZ-EQ5 is a patented dual-encoder motor system, Freedom-Find™, which allows users to move the mount manually without losing alignment. While most mounts lose their alignment once moved by hand, the AZ-EQ5 uses a proprietary slip clutch system that keeps your alignment whether you slew by hand or using the hand controller. After moving to the new object (electronically or manually), the mount will start tracking automatically.
42,000 Object Database
Using our proprietary SynScan hand controller, the AZ-EQ5 provides a user-friendly interface with automatic slewing to over 42,000 objects in the night sky. The hand controller can also connect to a computer using the supplied RS232 cable (USB adapter available), enabling computer control with most astronomy programs, including The SkyX, Stellarium, and Starry Night.
Whisper Quiet Motors
Sky-Watcher’s belt drive system has a few advantages over mounts using traditional stepper gearing. Belt drive systems deliver nearly silent slewing and tracking, making for an evening free of obnoxious motor noises while delivering spot on accuracy. Sky-Watcher’s belt drive also features minimal backlash, smoother tracking, and less periodic error than mounts using servo motors. For users looking to improve the accuracy of their tracking, the AZ-EQ5 also features built in Periodic Error Correction firmware, allowing users to fix periodic error in the field.
Periodic Error Correction Made Easy!
For the astrophotographers looking to reduce Periodic Error, the SynScan hand controller has built in PEC training that can be configured while in the field! Periodic Error is best described as tiny back-and-forth oscillations of target stars. This motion is not notable during visual observation, but during a long photographic exposure, can turn pinpoint stars to small streaks. Using Sky-Watcher’s built-in PEC training, astrophotographers can cut down on the problems caused by Periodic Error to get smoother tracking and better performance from an autoguider.
A Photographer’s Best Friend
The AZ-EQ5 mount has built in DSLR interface with the ability to control two cameras at once. Using a built in intervelometer timer, the SynScan hand controller can setup exposure length, number of frames taken and a ‘cool down’ period between each frame. Additionally, the SynScan hand controller has the ability to select up to 8 different exposure combinations. No need to purchase an expensive cable release when Sky-Watcher includes everything you’ll need to start shooting deep sky objects out of the box.
Use at Any Latitude
Thanks to the pier extension that sits between the mount head and tripod, the AZ-EQ5 can be polar aligned at almost any latitude. Most equatorial mounts have difficulty with polar alignment at lower latitudes due to the counterweight bar interfering with the tripod. The AZ-EQ5 bypasses this completely, using a beefy pier extension to elevate the mount head away from the tripod legs. The pier extension creates enough clearance between the counterweight bar and tripod legs that the mount can be polar aligned at virtually any latitude, from Alaska to Ecuador to Tierra del Fuego.
Ready to Go, Out of the Box!
While most mounts leave you high and dry to purchase accessories on your own, Sky-Watcher includes plenty of accessories to get you started. In addition to the SynScan hand controller and the pier tripod, the AZ-EQ5 mount comes with two 7.5lb counterweights and a counterweight extension bar, as well as an extra saddle for mounting a second scope for viewing in dual-OTA mode. The mount also includes two Canon EOS trigger cables for connecting your camera to the mount (Nikon and Sony cables available separate). A polar finderscope is also included to assist with setup. The AZ-EQ5 has a built in USB port for firmware updates, but also allows computer control using various astronomy software.

Sky-Watcher is a leader in the design and manufacturer of ED-APO systems. Sky-Watcher offers one of the most extensive lines of ED-APOCHROMATIC refractors in the world. Using only the finest fabrication materials available, Sky-Watcher APO refractors are manufactured to painstakingly rigorous, exacting standards of optical and mechanical quality to insure the amateur astronomer peak performance and a great experience each and every time a Sky-Watcher ED-APO is taken into the field. We know the amateur astronomer has very high expectations regarding astronomical equipment purchases. Sky-Watcher has been delivering consistent satisfaction for decades. This telescope is designed for a lifetime of astronomical enjoyment!
Observing with the Sky-Watcher EvoStar 100ED 100mm Refractor
Turning the telescope to the first quarter Moon, the Apennine Mountains snap into focus revealing a cornucopia of jagged mountain ridges, canyons, and numerous small craters in razor-sharp detail. Not far removed, reaching skyward the crater wall of Archimedes pops into view in bold relief against the smooth flatlands that transverse the distance between it and the Apennine Mountains. This is lunar observing at its best – HD style. The gas giant Jupiter displays its swirling equatorial bands in high-definition with festoons, and tonality within the bands. The great spot is clearly visible, discreetly contrasted from the surrounding Jovian landscape. Saturn’s storied surface phenomenon is simply stunning. Hunt down double stars like Epsilon Lyrae, the “double-double" in Lyra. A 100mm refractor will provide a crisp well defined image superior to even a larger reflector. Always a star-party favorite, Alberio located in the tail of Cygnus never fails to please as it is a beautiful double. Alberio appears like a gold sparkler and its companion looks blue-green. It is a perfect refractor object. Compact globular star clusters lend themselves well to a refractor. Located outside our galaxy the globular M2 will probably resolve more stars in a 4" refractor than a 6" reflector. M4, M10 and many other globular cluster can be seen well with a 100mm refractor. M13, the fantastic globular in Hercules is a stunning sight in a 100mm refractor. The bright central cores of prominent nebulae can be seen and the brightest stars can be resolved. This is just the beginning of an incredible journey of exploration possible with a SW ED-APO 100mm refractor. As an astrograph, the SW EvoStar 100ED APO performs superbly delivering crisp, high-fidelity imaging of planetary, lunar and aperture appropriate deep-space phenomenon.
Refractors—the Ultimate Imaging Instruments
In a given aperture size, refractors will always exhibit sharper images than other optical designs because the refractor concentrates more light into the central airy-disk and first diffraction rings. There is no diffraction pattern interference caused by a diagonal mirror, or secondary mirror being suspended in the optical path (central obstruction) as is the case with reflectors.
Sky-Watcher ED-APOs—the Ultimate Refractors
Sky-Watcher ED-APO refractors provide the finest images obtainable—bar none—in their design class. If you are on a quest for the ultimate in pristine, near textbook-perfect astronomical imaging, look no further! Sky-Watcher ED apochromatic refractors deliver dramatic coal-back skies and faithful, contrast-rich views of planetary and deep-space phenomenon that are second to none. Sky-Watcher ED-APO refractors are the logical choice as an investment in advanced instrumentation for exceptional viewing or photography.
Virtually Eliminates Residual Chromatic Aberration
The Sky-Watcher ED-APO design assures virtual elimination of residual “false color" (i.e. chromatic aberration) normally present in 2-element achromatic lens designs which utilize standard crown and flint glasses. Sky-Watcher APO refractors utilize the finest extra-low dispersion (ED) glass available, FPL-53. This results in the best color correction for an ED doublet lens.
Schott Glass Used in Selected Models for Crown Element
Select models of ED-APO refractors will benefit from the inclusion of Schott glass being used for the positive front Crown element in the objective. Schott is the recognized world leader in glass utilized for precision optical lens systems, including medical instrumentation, and famous-brand camera lenses. While Schott glass is only used in selected models, all other models utilize top-quality, Grade-A glass from perhaps less famous but, nonetheless, highly respected, high-quality glass manufacturers.
Pride and Perfection in Optical Manufacturing
Every lens element is individually inspected for purity and absence of striae and other image-degrading imperfections. Every lens is pitched polished to exacting standards of optical fabrication and performance by highly skilled opticians utilizing state-of-the-art methodology and rigidly controlled optical testing procedures. The result is high-quality, diffraction-limited optics performing to the theoretical limits of their respective aperture sizes. All lenses are uniformly air-spaced in their cell housings.
Metallic High-Transmission Lens Coatings
Each air-to-glass lens surface has exotic anti-reflection metallic coatings applied to ensure optimum light through-put. The proprietary Sky-Watcher “Metallic High-Transmission Coatings" (MHC) are the finest photon anti-rejection coatings in their class.
Light-Baffled Optical Systems
The objective lens cell is light-baffled to reject stray, unfocused light. The draw tube is likewise baffled to insure optimum contrast. The tube interior is flat blackened to help prevent unfocused internal light reflections from reaching the focal plane.
Precision 2" Crayford-style Focuser is Standard
Optical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision 2" Crayford-style focuser-assembly with 1.25 adaptor. This focuser operates at 2 speeds for fine and ultra-fine focusing adjustments.

SKY-WATCHER EvoStar 120ED APO REFRACTOR: Serious Amateurs will Love the SW 120mm ED-APO Refractor
Sky-Watcher high-performance ED-APO refractors offer premium optical performance for the discriminating amateur astronomer. Refractors are coveted for their superb contrast, high-definition and coal-black sky background that make stars appear like diamonds embedded in black velvet. SW APO refractors utilize the most modern optical glasses and fabricating techniques to deliver the ultimate in high-fidelity astronomical imaging. Subtle details pop as never seen before in telescopes of lesser optical capability.
Observing with the Sky-Watcher EvoStar 120ED APO Refractor
The additional aperture compared to a 100 mm diameter lens provides a dramatic increase in resolution and a heighten sense of seeing lunar and planetary surface phenomenon in seemingly 3D high-definition.
Touring the Moon…the rugged Southern Highlands of the lunar surface are rich in craters. To the southeast, the famous crater Theophilus is 65 miles across. The raised triple-peaked central area is striking to observe in your SW 120ED. The crater has massive walls and the basin is 14,000 feet deep. One of the southernmost craters, Clavius, is a very large crater 145 miles across. It is located south of Tycho. In this same area can be found craters Maginus and Longomotanus which are also very worthy of exploration. To the north, the young crater Tycho dominates the southern lunar landscape. Named after the famous Danish astronomer Tycho Brahe, it is a spectacular sight with very high-rimmed walls. Your SW120ED will provide an impressive view. North of Tycho appearing brightly in a basin is the famous Rupes Recta (the Straight Wall), an 800 foot mountain that is a “must see” for amateur astronomers. Your SW 120ED will show it clearly and sharply the way you want to see it. On the north end of Mare Nubium, almost on the lunar N-S and E-W center line can be found 3 craters grouped together: Arzachel a young impact crater 60 miles across and 13,000 feet deep shows a terraced structure and a system of channel-like narrow depressions in its basin called “rilles”. Nearby are Alphonsus, a 70 mile wide crater, and Ptolemaus a prominent ancient crater 90 miles across with a heavily worn dark interior. The Earth’s Moon offers a treasure trove of fascinating detail to explore with your SW 120ED-APO EQ5 PRO. We have only featured a relative few examples of what is available. The views you will experience are so clear and sharp it might just feel like a veritable space-walk.
Planets are spectacular…the inner solar-system presents the colorful rusty-red planet Mars. Mars is a challenge for amateur astronomers, but your SW 120ED will show some very interesting detail. Olympus Mons, a volcanic crater 375-miles across and 16-miles high, is just one of the quests your capable SW120ED can tackle. Nirgal Vallis is a channel 600 miles long that responds well to the razor sharp contrast provided by the SW 120ED. The Grand Canyon of Mars, Valles Mariners, dwarfs that of our Earth’s Grand Canyon, but it still requires superb optics to view even though it is 150 miles wide and 4 miles deep. When prominent, the gleaming white Mars’ polar cap is in stark contrast to the redish-orange surface landscape of the rest of the planet. The SW 120ED will show you this detail like you want to see it. The gas giant Jupiter displays its swirling equatorial bands in high-definition with festoons and tonality within the bands. With regular observation, you will be able to follow storms and disturbances cross the planet in the southern equatorial band. Saturn’s storied surface phenomenon is simply stunning. View the rings and clearly see Cassini’s Division and cloud belts across its equator.
View Wonders of Deep-Space…beyond the solar-system hunt down double stars like Epsilon Lyrae, and the “double-double” in Lyra. A 120 mm ED-APO refractor will provide a crisp well defined image on par with up to a 7″ reflector. Always a star-party favorite, the beautiful double Alberio located in the tail of Cygnus is sensational. Alberio appears like a gold sparkler and its companion looks like a blue-green sparkler. It is a perfect object to view with your SW 120ED. Algol, an eclipsing variable star, sometimes called the “winking eye” fluctuates in brightness and is a suitable subject for the SW 120ED. Aldebaran, a beautiful orange giant in the Constellation Taurus is a delightful sight to view with the SW 120ED. In the eastern corner of Constellation Orion, Rigel, a bright blue double has a blue-green companion that requires excellent optics to see, a worthy subject for the SW 120ED. Tight globular star clusters like M13 in the Constellation Hercules appear like a beehive of crisp stellar pin points circling the central core, star upon thousands of stars. Compact globular star clusters lend themselves well to a refractor. M5 is a worthy object for viewing. M92, in the Constellation Hercules, is very compact globular with a bright core. It is a great object to view with the SW 120ED. M4, M10 and many other globular clusters can be seen well with the SW 120ED-APO refractor. The bright central cores of prominent nebulae can be seen and the brightest stars can be observed illuminating the glowing nebulosity which appears as ghostly apparitions.
The superb capabilities of the SW 120ED provide performance on a par with a reflector of perhaps up to 7″ in diameter on lunar, planetary, double-stars, globular star clusters, and depending on your ranking of unobstructed high-contrast as a necessary attribute, even the brighter nebulae may look better to you in a SW 120ED. These objects will stand out in bold relief contrasted against a very dark velvet-black sky background. Many advanced amateur astronomers feel the ED-APO experience is astronomy’s richest.
As an astrograph, the SW EvoStar 120ED APO performs superbly delivering crisp, high-fidelity imaging of planetary, lunar and aperture appropriate deep-space phenomenon.

Sky-Watcher EvoStar 80ED APO Refractor: Portable Optical Powerhouse!
Due to their unobstructed textbook-like diffraction patterns and exotic optical properties, the ED-APO produces the sharpest, highest quality imaging obtainable from any telescope optical design. These breathtakingly pristine celestial views are coveted by experienced amateur astronomers.
Observing with SW EvoStar 80ED 80 mm Refractor
Fortunate indeed is the amateur astronomer with a SW ED-APO 80 mm refractor on a clear night with transparent skies and a stable atmosphere. The Sky-Watcher ED-APO 80mm is a modestly wide-field telescope offering bright, wide swaths of sky in a single view. It is well suited for wide-field astronomical observation of prominent nebulae, star clusters and galaxies from a dark-sky location, or can be used as an astrograph for sky photography. As a terrestrial spotting scope or telephoto lens, the ED-APO’s performance is absolutely superb. Ultra high contrast allows the subtlest of details to be easily scrutinized under conditions of good seeing. The petite silhouette of the SW ED-APO 80 mm makes for an excellent compact, portable telescope that travels light and fits a small space. At about 50-power, structural detail becomes apparent in our solar system’s gas giants like Saturn and Jupiter. The Moon also exhibits striking crater detail along the lunar terminator.
As an astrograph, the SW EvoStar 80ED delivers superb performance imaging a wide spectrum of astronomical phenomenon.
Refractors—the Ultimate Imaging Instruments
In a given aperture size, refractors will always exhibit sharper images than other optical designs because the refractor concentrates more light into the central airy-disk and first diffraction rings. There is no diffraction pattern interference caused by a diagonal mirror, or secondary mirror being suspended in the optical path (central obstruction) as is the case with reflectors.
Sky-Watcher ED-APOs—the Ultimate Refractors
Sky-Watcher ED-APO refractors provide the finest images obtainable—bar none—in their design class. If you are on a quest for the ultimate in pristine, near textbook-perfect astronomical imaging, look no further! Sky-Watcher ED apochromatic refractors deliver dramatic coal-black skies and faithful, contrast-rich views of planetary and deep-space phenomenon that are second to none. Sky-Watcher ED-APO refractors are the logical choice as an investment in advanced instrumentation for exceptional viewing or photography.
Virtually Eliminates Residual Chromatic Aberration
The Sky-Watcher ED-APO design assures virtual elimination of residual “false color” (i.e. chromatic aberration) normally present in 2-element achromatic lens designs which utilize standard crown and flint glasses.
Sky-Watcher APO refractors utilize the finest extra-low dispersion (ED) glass available, FPL-53. This results in the best color correction for an ED doublet lens.
Schott Glass Used for Front Crown Element and ED 2 Lens Element
The P80ED will benefit from the inclusion of Schott glass being used for the positive front Crown element in the objective. Schott is the recognized world leader in glass utilized for precision optical lens systems, including medical instrumentation and famous-brand camera lenses. While Schott glass is only used in selected models, all other models utilize top-quality, Grade-A glass from perhaps less famous but, nonetheless, highly respected, high-quality glass manufacturers.
Pride and Perfection in Optical Manufacturing
Every lens element is individually inspected for purity and absence of striae and other image-degrading imperfections. Every lens is pitched polished to exacting standards of optical fabrication and performance by highly skilled opticians utilizing state-of-the-art methodology and rigidly controlled optical testing procedures. The result is high-quality, diffraction-limited optics performing to the theoretical limits of their respective aperture sizes. All lenses are uniformly air-spaced in their cell housings.

Sky-Watcher 8" DOB - Join the Ranks of Serious Observers
Corresponding to the escalating "aperture fever" that has gripped amateur astronomy for several decades, an 8" diameter is now generally regarded as the minimum entry-level aperture for serious observing. The low cost, large diameter, and fast focal ratio of the 8" Sky-Watcher Dobsonian make it an ideal dedicated telescope for wide-field, deep-space observation of faint galaxies, nebulae, and star clusters. The low-power dramatically captures wide swaths of sky in a single view. Galaxies and nebula appear to pop out of the heavens as bright, expansive masses of stars, gas, and dust.
Observing with the 8" Sky-Watcher Dobsonian
If you have never before observed through a high-quality, wide-field Dobsonian, like the SW 8" DOB, you are in for one of the sweetest experiences in amateur astronomy. Imagine the exhilaration of opening a clam and discovering a pearl. The sky is full of pearls, astronomical pearls. While they won't make you rich in the financial sense, for amateur astronomers at least, observing the fabled pearls of deep-space is a rich and even exhilarating pastime. A catharsis for the soul that renders the mundane insignificant, and reconnects us with the inner child who revels in awe and wonderment. A night observing with the SW 8" Dob can leave you with a lingering sense of contentment long after the evening's viewing is over. Some of amateur astronomy's most revered and enthusiastically observed extra solar-system objects are now within your reach. This instrumentation provides entry into the brotherhood of serious amateur astronomers—you have arrived! The summer sky is aglow with astronomical pearls. In the constellation Sagittarius several of the sky's most prominent emission nebulae can be seen well in your 8" SW DOB. 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. The Lagoon Nebula appears fiery red in astrophotographs due to the hot hydrogen gas. Located nearby is the smaller, but very beautiful Trifid Nebula (M20). These two nebulae can actually be seen in the same field of view. The magnificent Swan Nebula (M17) is also located in Sagittarius. It is named the Swan for its resemblance to the stately bird. The sky's most awesome globular star cluster, M13, is located in the constellation Hercules, a bee-hive of thousands of stars swarming about a central core. Globular clusters are no longer being formed in the universe, so you are observing fossil light, a glimpse back in time. This is the brightest object of its kind and always a treat to view. The globular cluster M92 is likewise very interesting and can also be found in Hercules. The winter sky holds several stunning pearls oft referred to in popular culture, not just astronomy. Our closest external galaxy, the beautiful Andromeda, perhaps the defining galaxy of the classic spiral form can essentially be seen almost in its entirety within one eyepiece field. Winter's diffuse Great Orion Nebula (M42) is the brightest emission nebula in the heavens. While it can be seen with the naked eye from a dark location, it is nothing less than spectacular in an 8" SW DOB. A billowing cloud-like cauldron of dust and gasses illuminated by large, intensely glowing youthful stars, this object is perhaps the mother of all pearls. The preceding is just a short sampling of objects that can be seen. Many more pearls of the night sky await you.
Sky-Watcher Dobsonians Epitomize Ease-of-Use
Observing with a Dobsonian has been described akin to shooting ducks in a gallery because it is so easy to find your target. Just swing your SW DOB to the quadrant of sky to be searched, and scan the vicinity. An 8x50mm Right Angle optical viewfinder provides both magnification and light-gathering to help narrow your search for those elusive fuzzies when star-hopping. The standard-equipment backlash-free 2" Crayford Focuser insures ultra smooth focusing adjustments. Multi-coated, 4-element Plössl eyepieces (25mm and 10mm) provide a spacious 52° Apparent Field of View. To ensure mechanical ease-of-use, SW uses a high-performance Teflon bearing system in both axes combined with tension adjustment in altitude to facilitate setting the appropriate amount of friction, assuring smooth vertical and horizontal manual movement without free-play from small bumps or gusts of wind. This also eliminates the need to have a balanced optical tube as in an equatorial mount. Sky-Watcher's Teflon bearing system is preferable to the use of ball-bearings. Ball-bearings make unintended movement of the optical tube more difficult to control. Fortunately, at low power, deep-space objects leisurely drift through the field of the SW 8" DOB, so constant mechanical adjustment of the telescope's orientation isn't needed to keep objects in the field of view. Sky-Watcher's revolutionary truss-support concept allows the optical tube's front and back cells to collapse together, aligning on the truss support rods which can then be locked down for easy and secure telescope transport. This one piece, low-hassle OTA design is mechanically simple and results in large aperture telescopes that can be reasonably handled and transported by one individual. This innovation gives Sky-Watcher users tremendous functional ease-of-transportability.
Sky-Watcher Uses Quality Components Throughout
The Sky-Watcher 8" DOB utilizes quality components throughout. Pride of workmanship manifests itself in high quality standards of optical and mechanical fabrication. The polishing process for primary and diagonal mirror yields smooth mirror surfaces ensuring good contrast, and properly corrected optics show minimum alterations to the optical wave-front. On each primary mirror, and elliptical diagonal mirror aluminum is vacuum deposited to the front glass surface and then over coated with hard quartz (SiO4). Additional layers of Titanium Dioxide (TiO2) and (SiO4) are then applied. Dust covers help keep your DOB clean when not in use. The mechanical and structural components of the OTA exhibit rigid construction and outstanding stability. The mount construction is sturdy and rigid. Mount design, while simple, facilitates smooth motions about both axes. Quality accessories enhance the observer's viewing experience.

This innovation gives Sky-Watcher users tremendous functional ease-of-transportability.
Viewing with the SW 10"—Size Does Matter
In viewing deep-space, aperture matters—big time! With this telescope you have tremendous light gathering power. Prominent deep-space objects seen well in an 8" SW DOB, such as diffuse emission nebulae in the summer sky like the Lagoon (M8), Trifid (M20), and Swan (M17); the stunning globular star clusters M13 and M92 in Constellation Hercules; the awesome winter sky's Great Orion Nebula (M42) in Constellation Orion, and our enormous local galaxy group companion the Andromeda Galaxy (M31) in Constellation Andromeda, to name a very few, will appear more spectacular, brilliant, and wider in extension in a SW 10" DOB. Many challenging objects for an 8" aperture now come into their own with the SW 10" DOB: the planetary nebula the Crab (M1), a supernova remnant, requires a 10" aperture to truly begin to appreciate the several subtle, gaseous filamentary structures. M33 the spiral galaxy in Constellation Triangulum exhibits significantly more open arm structure. The Rosette Nebula in Monoceros begins to show the discernible pattern of a blooming rose. M51, the fascinating spiral Whirlpool Galaxy, displays remarkable greater structural detail in a 10" aperture vs. 8" diameter size telescope. There is no question the incremental resolving power of a 10-inch aperture is visually impressive when compared to an 8-inch. 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, collapsible optical tube design makes the decision to step up in aperture to a 10" even easier.
Sky-Watcher 10" DOB – a Class Act!
The Sky-Watcher 10" DOB utilizes quality components throughout. Pride of workmanship manifests itself in high quality standards of optical and mechanical fabrication. The polishing process for primary and diagonal mirror yields smooth mirror surfaces ensuring good contrast, and properly corrected optics show minimum alterations to the optical wave-front. On each parabolic primary mirror, and elliptical diagonal mirror aluminum is vacuum deposited to the front glass surface and then over coated with hard quartz (SiO4). Additional layers of Titanium Dioxide (TiO2) and (SiO4) are then applied The mechanical and structural components of the OTA exhibit rigid construction and outstanding stability. The mount construction is sturdy and rigid. Mount design, while simple, facilitates smooth motions about both axes. Quality accessories enhance the observer's viewing experience.
Sky-Watcher Dobsonians Epitomize Ease-of-Use
Observing with a Dobsonian has been described akin to shooting ducks in a gallery because it is so easy to find your target. Just swing your SW DOB to the quadrant of sky to be searched, and scan the vicinity. An 8x50mm Right Angle optical viewfinder provides both magnification and light gathering to help narrow your search for those elusive fuzzies when star-hopping. The standard-equipment backlash-free 2" Crayford Focuser insures ultra smooth focusing adjustments. Multi-coated, 4-element Plössl eyepieces (25mm and 10mm) provide a spacious 52° Apparent Field of View. To ensure mechanical ease-of-use, SW uses a high-performance Teflon bearing system in both axes combined with tension adjustment in altitude to facilitate setting the appropriate amount of friction, assuring smooth vertical and horizontal manual movement without free-play from small bumps or gusts of wind. This also eliminates the need to have a balanced optical tube as in an equatorial mount. Sky-Watcher's Teflon bearing system is preferable to the use of ball-bearings. Ball-bearings make unintended movement of the optical tube more difficult to control. Fortunately, at low power, deep-space objects leisurely drift through the field of the SW 10" DOB, so constant mechanical adjustment of the telescope's orientation isn't needed to keep objects in the field of view.

Sky-Watcher 12" DOB: Deep-Space Hero!
The Sky-Watcher 12" DOB is a big gun. If you are shooting for well resolved, elusive 12th-magnitude fuzzies, you now have the power. In fact, a very significant wow-factor extends down to viewing the stuff people usually concentrate on with 8" and 10" telescopes. Except they say, "WOW!", when they view through this super aperture amateur 12" SW telescope. You can not only be a hero to yourself, but a mystical guru to other backyard astronomers, scout groups, friends, and neighbors. Astronomy is a great hobby to share, and a SW 12" DOB makes you potentially the hit of any star party. Well, so much for ego satisfaction—the point is—the SW 12" DOB is a serious telescope that will be purchased by a serious amateur who wants serious deep-sky penetrating resolution. Be advised this Light Chariot is one sweet astronomical ride!
Viewing through the SW 12" DOB
Everything in deep-space appears brighter, and wider in extension with the SW 12" DOB. Many of the more challenging to resolve objects in smaller diameter telescopes now reveal their essential structure. Objects just within the threshold of a 10" aperture now appear more prominent and may be worth dwelling upon for extended periods. Comet hunters will delight in the fainter magnitudes that are possible to discern in the SW 12" DOB. Here at last is a telescope within the threshold to tackle elusive deep-space gems like the Horsehead Nebula in Constellation Orion. Located in Constellation Perseus, M76, is a very faint nebula of 11th magnitude. The SW 12" will capture this baby like you want to see it. M97, a planetary nebula in Ursa Major is very faint, but as a serious amateur you will want to see it. No worries, the SW 12" DOB will fulfill your quest. M61, a spiral galaxy in Constellation Virgo, will reveal spiral arms as you would hope to see them, but you will need a SW 12" telescope to resolve them well. The list goes on, and you will delight in planning your own journey of exploration. The incremental resolving power of the SW 12" aperture is beyond just being impressive, it's within amateur astronomy's super aperture threshold where the lucky observer is able to resolve well, many, many objects that smaller telescopes just don't have the horsepower to detail satisfactorily because they can't pull in enough light. Again, Sky-Watcher's compact, collapsible optical tube design makes this super aperture 12" DOB a far more practical decision to purchase.
