Skywatcher Reflector Quattro Imaging Newtonian - 10", 250P

Description

The Skywatcher Reflector Quattro Imaging Newtonian - 10", 250P 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 is 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-Watchers proprietary Radiant Aluminum Quartz (RAQ), producing 94% reflectivity. The tube is constructed with rolled steel, then coated with Sky-Watchers 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.

Included with the Quattro imaging Newtonian is a 10:1 dual-speed 2-inch Crayford-style focuser, 1.25 and 2-inch eyepiece adapters, a 9x50 finderscope, tube rings, and a V-style dovetail plate.
