Sky-Watcher 12 Inch Dobsonian Telescope S11740 Product Info

The Sky-Watcher 12 Inch Dobsonian Telescope S11740 is considered the big gun of all the Sky Watcher Dobsonian Telescopes ( 8 inch Dobsonian and 10 inch Dobsonian) respectively. With this Sky Watcher telescope, the serious amateur would be the star of the party, and would be able to view in a serious deep-sky resolution.

Observing with the Sky-Watcher 12 Inch Dobsonian Telescope

With this telescope by Sky Watcher, everything in deep space appears brighter, and wider. Many of the more challenging to unravel objects in smaller diameter telescopes now reveal their essential structure. Objects just within the threshold of a 10 inch aperture now appear more noticeable and may be worth focusing on for more extended periods. With the Sky-Watcher 12" Dobsonian Telescope it is now possible to tackle subtle deep-space gems like the Horsehead Nebula in Constellation Orion. Located in Constellation Perseus (M76), is a very week nebula of 11th magnitude. The 12 Inch Dobsonian will capture it with ease. M97 a planetary nebula in Ursa Major is very faint, but as a serious amateur, the obeserver would again be able to get a nice view of it. M61, a spiral galaxy in Constellation Virgo, will reveal reveal spiral arms with the 12in Dobsonian Telescope by Sky Watcher. And the list goes planning a whole journey of exploration.

The 12 Inch Sky-Watcher Establishes a New Standard in Large Aperture Ease of Use

Observing with a Dobsonian 8 inch Telescope has been compared to shooting ducks in a gallery because it is so easy to find a target for observation. Just swing the telescope by Sky watcher to the sky, and scan the proximity. An 8x50mm Right Angle optical viewfinder provides both magnification and light-gathering to help narrow your search for the stars. The standard equipment backlash-free 2 Inch Crayford Focuser provides ultra smooth focusing adjustments. Multi-coated, 4 element eyepieces (25mm and 10mm) provide a spacious 52? 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 assist setting the appropriate amount of friction, assuring smooth vertical and horizontal manual movement without any distraction 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 telescope, so constant mechanical adjustment of the Sky Watcher telescope's orientation isn't needed to keep objects in the field of view.

The Sky-Watcher telescope uses a revolutionary truss-support concept which 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.

Sky Watcher Dobsonian Telescope Quality Components

The Sky-Watcher 12 Inch Dobsonian Telescope S11740 uses quality components throughout with a pride of workmanship in high quality standards of optical and mechanical construction. The polishing process for the primary and diagonal mirror provides smooth mirror surfaces to assure good contrast. On each primary mirror, and elliptical diagonal mirror, aluminum is vacuum deposited to the front glass surface and then over coated with hard quartz. Additional layers of Titanium Dioxide and hard quartz are then applied. Dust covers help keep the telescope by Sky Watcher clean when not in use.
