Sky-Watcher BK DOB 10" SYNSCAN

"Sky-Watchers GoTo Dobsonian
High-tech meets bargain-telescope design. A shotgun marriage or a match made in heaven? We find out!"

"Could the new Sky-Watcher SynScan telescopes really work? ...my doubts were allayed the first night out.Our test telescope,on loan from Pacific Telescope Corp., worked great. Surprisingly so."

- Alan Dyer wrote in his 3-page review of the Sky-Watcher GoTo Dobsonian telescope at SkyNews November/December 2010 issue (www.skynews.ca | review).

Sky-Watcher improves on the often unwieldy standard design of Dobsonians with their 10" f/4.7 Collapsible GoTo Dobsonian Telescope. It features a patented truss tube system that enables the front corrector plate/eyepiece assembly to be moved back and locked against the main rear tube to greatly reduce the size of the OTA for storage and transportation. This open OTA also has the benefit of reducing overall weight versus standard Dobs. To add another level of usability to the scope is a motorized ground-based rocker alt-az mount. Equipped with dual servo motors, they are controlled using the SynScan computer hand controller. This self-contained system features over 42,000 celestial objects with alignment assistance, guided tours and full go-to capabilities. Its dual encoders, coupled with the patented Tension Control Handle, enable users to manually move the scope without having to realign it.

It features a large 10" aperture parabolic mirror that captures enough light to make detailed observations of the Moon and planets, and still reach out past our solar system to discover deep-sky subjects such as nebulae, globular clusters, and galaxies. Its f/4.7 focal ratio and Crayford focuser makes this an ideal choice for imaging. Its relatively fast focal ratio enables devices to capture images in less time than slower scopes, while the unique focusing mechanism employed in the Crayford-style gives it the ability to achieve tack-sharp focusing with zero back-lash that rack-and-pinion focusers generally are unable to achieve.
