- 305mm aperture, 1200mm focal length
- Fast f/4 focal ratio
- Parabolic mirror designed for imaging with 94% reflectivity
- 10:1, dual-speed, 2-inch Crayford-style focuser
- Oversized secondary mirror produces greater illumination for full-frame DSLR and CCD cameras
- Tube rings, mounting plate, eyepiece adapters, and 9x50 finderscope included
The Sky-Watcher Quattro 300P imaging Newtonian 12" # S11230 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.
Agena Astro affiliate AstroBackyard shared this video on the Sky-Watcher Quattro 300p:
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.
Included with the Quattro imaging Newtonian is a 10:1 dual-speed 2-inch Crayford-style focuser, 1.25 and 2-inch eyepiece adapter, a 9x50 finderscope, tube rings, and a D-style dovetail plate.
