Sky-Watcher 10" f/3.94 Quattro Imaging Newtonian Telescope (OTA Only)

Sky-Watcher's 10" f/3.94 Quattro Imaging Newtonian Telescope has been specifically engineered for astrophotography and astro-imaging performance. Its 1000mm focal length has been shortened to produce a fast f/3.94 focal ratio which helps to reduce the exposure times required for capturing detailed images of the Moon, planets, and deep-sky objects. To further help boost its performance are borosilicate mirrors which have a low coefficient of thermal expansion to reduce the effects of expansion/contraction due to temperature fluctuation. This helps limit distortion that can occur when moving the OTA from indoors to outdoors and limiting the scope's ability to resolve details. The entire optical system is fully multicoated to increase the reflectivity of all surfaces to produce brighter and sharper images.
