Sky Watcher 305mm 12 F/1500 Truss Tube Black Diamond Product Info

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 39 the point is 39 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 1 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 39 s within amateur astronomy 39 s super aperture threshold where the lucky observer is able to resolve well, many, many objects that smaller telescopes just don 39 t have the horsepower to detail satisfactorily because they can 39 t pull in enough light. Again, Sky Watcher 39 s compact, collapsible optical tube design makes this super aperture 12 DOB a far more practical decision to purchase.

The 12 Sky Watcher Establishes a New Standard in Large Aperture 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 Plossl 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 39 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 12 DOB, so constant mechanical adjustment of the telescope 39 s orientation isn 39 t needed to keep objects in the field of view.

Sky Watcher 39 s revolutionary truss support concept allows the optical tube 39 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 1 piece, low hassle OTA design is mechanically simple and results in large aperture telescopes that can be reasonably handled and transported by 1 individual. This innovation gives Sky Watcher users tremendous functional ease of transportability.

Sky Watcher Uses Quality Components Throughout

The Sky Watcher 12 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 are provided to help keep your DOB clean when not being used.

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 39 s viewing experience.
