Celestron CGEM II Computerized German Type Motorized Equatorial Mount vs Celestron EdgeHD 800 OTA

The Celestron EdgeHD 800 OTA is the clear winner. While the CGEM II mount offers computerized tracking and GoTo capabilities, it scores significantly lower across nearly every performance metric, particularly in planetary observation (23 vs 69) and deep sky work (23 vs 59). The EdgeHD 800 OTA's 203mm aperture and superior optical design deliver substantially better light-gathering and image quality that justify the $570 price premium.

The single most important differentiator is aperture and optical quality. The CGEM II is a compact, portable mount system; the EdgeHD 800 OTA is a serious optical instrument. These serve entirely different purposes. The CGEM II Computerized German Type Motorized Equatorial Mount suits observers who prioritize convenience and portability over image quality, though its low planetary and deep sky scores make it suitable primarily for casual lunar observation.

The Celestron EdgeHD 800 OTA belongs with observers seeking genuine planetary detail and deep sky performance, even if it requires separate mount investment. Buy the EdgeHD 800 OTA if you're serious about astronomy. The CGEM II's convenience cannot compensate for its optical limitations.
