Sky-Watcher 12" f/5 Flextube Dobsonian Telescope

The Sky-Watcher 12" f/5 Flextube Dobsonian Telescope 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 12" Sky-Watcher telescope. The 12" Dobsonian Telescope by Sky-Watcher is a serious telescope that will be purchased by a serious amateur who wants serious deep-sky penetrating resolution. You can be the hit of any star party. Be advised this Light Chariot is one sweet astronomical ride!

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'll want to see it. M61, a spiral galaxy in Virgo, will reveal spiral arms as you would hope to see them, but you will need a SW 12" telescope to resolve them well.

Observing with the 12" Sky-Watcher Dobsonian:

If you have never before observed through a high-quality, wide-field Dobsonian, like the Sky-Watcher 12" DOB, you are in for one of the sweetest experiences in amateur astronomy. Some of amateur astronomy's most revered and enthusiastically observed extra solar-system objects are now within your reach. 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 Sky-Watcher DOB to the quadrant of sky to be searched, and scan the vicinity. An 8x50 mm right-angle erect viewfinder helps your search for those elusive fuzzies when star-hopping. At low power, deep-space objects leisurely drift through the field of the Sky-Watcher 12" DOB, so constant mechanical adjustment of the telescope's orientation isn't needed to keep objects in the field of view.

The standard-equipment backlash-free 2" Crayford Focuser ensures ultra smooth focusing adjustments. Multi-coated, 4-element Plossl eyepieces (25 mm and 10 mm) provide a spacious 52-degree Apparent Field of View. To ensure mechanical ease-of-use, Sky-Watcher 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 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 innovation provides a one piece, low-hassle OTA design, mechanically simple and results in large aperture telescopes that can be reasonably handled and transported by one individual.

Sky-Watcher Uses Quality Components Throughout:

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. Mount design, while simple, facilitates smooth motions about both axes. Quality accessories enhance your viewing experience.

In order to achieve focus while using a binoviewer without a corrector or Barlow lens, these Sky-Watcher Collapsible Truss Tube Dobsonians have an additional set of holes to allow the diagonal mirror cage to be lowered to a predetermined locking position on the truss poles. This enables binoviewing without unnecessary excess magnification.
