Sky-Watcher Quattro 6" Imaging Newtonian - Includes Corrector!
The Skywatcher 150P Quattro Imaging Newtonian is ideal for users searching for a fast imaging system that will work for both astrophotography and visual astronomy. Boasting a fast native focal ratio of f/4, this telescope can produce an exposure 8.4x faster than the average 8-inch f/10 Schmidt Cassegrain telescope when it is fitted with the included coma corrector/reducer, which brings the effective focal ratio down to f/3.4 5. Although designed as an imaging optical tube, this Newtonian also produces bright and detailed viewing for visual astronomy.
Like all Sky-Watcher reflectors, the 6" Quattro Imaging Newtonian features borosilicate mirrors coated with Sky-Watcher’s proprietary Radiant ™ Aluminum Quartz (RAQ™) coatings, 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 a coma corrector/reducer is included for those who want to take their imaging to the next level.
Included with the Skywatcher 150P Quattro Newtonian is a 11:1 dual-speed 2" Crayford-style focuser, 1.25" and 2" eyepiece adapters, a 6x30 finderscope, tube rings, V-style dovetail plate, a 70° Ultra Wide 22mm eyepiece, and coma corrector/reducer.
