The Sky-Watcher 6" 150P Quattro Imaging Newtonian Reflector Optical Tube Assembly is fantastic for both imaging and visual use, thanks to its fast f/3.9 focal ratio and parabolic borosilicate mirror with Sky-Watcher's Radiant Aluminum Quartz (RAQ) coatings which results in 94% reflectivity! With its fast focal ratio and wide field of view, it is an excellent choice for deep sky observing with exposures 6x faster than a 8" f/10 Schmidt Cassegrain design. For imagers using full frame sensors, the oversized secondary mirror helps provide greater illumination to accomodate these sensors!

• Sky-Watcher 6" 150P Quattro Imaging Newtonian Reflector Optical Tube Assembly is great for both amateur visual and astrophotographers alike!
• Fast f/3.9 focal ratio makes the telescope a great instrument for deep sky observing due to its wide field of view!
• Parabolic borosilicate mirror with RAQ coatings ensures the maximum possible light transmission and reflectivity, crucial for good imaging exposures.
• Full frame sensors (both DSLR and CCD) can be used due to oversized secondary mirror
• The optical tube is composed of rolled steel and coated with Sky-Watcher's glossy Black Diamond finish.
• The telescope comes with a 11:1, dual-speed, 2-inch Crayford-style focuser, 1.25" and 2" eyepiece adapters, 6x30 finderscope, tube rings, V-style dovetail and 70° Ultra Wide 22mm eyepiece and coma corrector/reducer.
