Sky-Watcher 12" f/4.9 Collapsible GoTo Dobsonian Telescope

BH #SK12GTCD • MFR #S11820
Sky-Watcher
Sky-Watcher 12" f/4.9 Collapsible GoTo Dobsonian Telescope
Key Features
  • Patented Collapsible OTA Design
  • 12" / 305mm Aperture
  • 1500mm Focal Length, f/4.9 Focal Ratio
  • 8x50 Straight-View Finderscope
Sky-Watcher improves on the often unwieldy standard design of Dobsonians with their 12" f/4.9 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.

Sky-Watcher improves on the often unwieldy standard design of Dobsonians with their 12" f/4.9 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 12" 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/4.9 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.
