Skywatcher Quattro 200P 8" Imaging Newtonian Product Info

The Quattro imaging Newtonian is an affordable, large aperture astrograph, ideal for users searching for a fast imaging system that will work for both astrophotography and visual astronomy. Boasting a swift f/4 focal ratio, this astrograph can produce an exposure 6x faster than the average 8-inch f/10 Schmidt Cassegrain telescope. Although designed as an imaging optical tube, these Newtonians also produce bright and detailed viewing for visual astronomy.

Like all Sky-Watcher reflectors, the Quattro imaging Newtonian features borosilicate mirrors coated with Sky-Watcher’s proprietary Radiant ™ Aluminum Quartz (RAQ™), producing 94% reflectivity. The tube is constructed with rolled steel, then coated with Sky-Watcher’s signature glossy metal-flake Black Diamond finish. The OTA uses an oversized secondary mirror providing greater illumination for DSLRs and CCDs using full-frame sensors, and an optional coma corrector is available for those who want to take their imaging to the next level.
