Quattro 250P Imaging Newtonian 10"

The Quattro 250P is an affordable, large aperture Newtonian astrograph featuring a swift f/4 focal ratio that can produce exposures 6 times faster than an 8-inch f/10 Schmidt Cassegrain telescope. The optical tube includes 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. 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. Although designed as an imaging optical tube, these Newtonians also produce bright and detailed viewing for visual astronomy.
