Sky-Watcher 8" f/3.9 Quattro Imaging Newtonian Telescope (OTA Only)

Sky-Watcher's 8" f/3.9 Quattro Imaging Newtonian Telescope is specifically engineered for astrophotography and astro-imaging performance. Its shortened 800mm focal length produces a fast f/3.9 focal ratio to reduce the exposure times required for capturing detailed images of the Moon, planets, and deep-sky objects. To further boost performance, borosilicate mirrors with a low coefficient of thermal expansion to reduce the effects of expansion/contraction when the temperature fluctuates. This helps limit distortion that can occur when moving the OTA from indoors to outdoors. The entire optical system is fully multicoated to increase the reflectivity of all surfaces to produce brighter and sharper images.
