Sky-Watcher Quattro 10" Imaging Newtonian OTA

The Sky-Watcher Quattro 10" (254 mm) Imaging Newtonian OTA is a great optical tube assembly for either visual astronomy or astro-imaging work. It would be a great choice for upgrading from a smaller entry level scope to a more advanced scope for serious observations or imaging. This fast 10" f/4 Newtonian telescope has a superb mirror set that is fully multi-coated, allowing you to see sharp, high contrast images of celestial objects. Additionally, the tube length has been slightly shortened to optimize performance for doing prime-focus photography. A 2" dual speed 10:1 ratio focuser is included for precision focusing adjustments, and an 8x50 finderscope will provide bright views when you're hunting down your favorite deep-sky object.

Sky-Watcher has designed a custom coma corrector for those astro-imagers with larger imaging sensors. The optional Quattro Coma Corrector will improve both visual and photographic performance by correcting for coma around the edges of the field of view, a normal aberration found in optical systems using parabolic mirrors, such as a Newtonian telescope.

Because this Sky-Watcher Quattro 10" Imaging Newtonian OTA incorporates significant improvements over competing fast Newtonians, you will be assured of rewarding views of many celestial objects and also achieve good image results when doing astroimaging.
