The CGEM II 925 HD combines Celestron's newly redesigned CGEM II computerized equatorial mount with its acclaimed EdgeHD optical system, offering over 9 inches of aperture with premium StarBright XLT coatings and diffraction-limited performance that delivers more resolution than the 8-inch model with less weight than the 11-inch. EdgeHD is an aplanatic, flat-field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view, with an astrograph-quality flat focal plane all the way to the edge of the field. The CGEM II mount is capable of carrying Celestron's higher-end SCT optical tubes securely and vibration-free while holding 40 lbs of payload and slewing at 5° per second, making it ideal for both imaging and visual observing. This system is particularly well-suited for astrophotographers seeking sharp, flat-field performance and serious visual observers pursuing deep-sky and planetary observing.
