Sky-Watcher 10" DOB. The sweet spot for  Aperture and Value

The SW 10" DOB is an very satisfying telescope to own, an instrument that will provide a lifetime of continuing exploration of the heavens. This telescope will hit the sweet spot for many amateurs, providing all the capability and value you are seeking in a large aperture telescope. Sky-Watcher's revolutionary truss-support concept allows the optical tube's front and back cells to collapse together, aligning 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 a large aperture telescope that can be reasonably handled and transported by one individual. This innovation gives Sky-Watcher users tremendous functional ease-of-transportability.  

Viewing with the SW 10"—Size Does Matter 

What may be 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 discernable 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. The 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, maintaining solid collimation from zenith to horizon. 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 

Movement on both axis is smooth with no back-lash. Just swing your SW DOB to the quadrant of sky, 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 Plossl eyepieces (25mm and 10mm) provide a spacious 52degree 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.
