The Celestron CGEM II 8" Edge HD Telescope combines advanced flat-field optics with a sturdy computerized equatorial mount to deliver unmatched clarity for visual astronomy and deep-sky astrophotography. Featuring an 8-inch aperture and premium StarBright XLT coatings, this system offers high light-gathering power and sharp pinpoint stars across large camera sensors. Built for accuracy, the heavy-duty mount easily supports demanding astro-imaging equipment with vibration-free stability.
Unmatched Optical ExcellenceMastering Deep Sky Imaging Systems
Designed to produce aberration-free images across a wide visual and photographic field of view, the Celestron CGEM II 8" Edge HD Telescope features an aplanatic, flat-field Schmidt-Cassegrain optical tube assembly. Integrated mirror clutches and rear tube cooling vents ensure optimal thermal balance and minimal image shift during long-exposure astrophotography. The heavy-duty CGEM II computerized equatorial mount boasts a 40 lb payload capacity, Permanent Periodic Error Correction (PEC), and Celestron’s innovative All-Star Polar Alignment software. Whether configured at its native f/10, f/7 with an optional reducer, or ultra-fast f/2 via Fastar compatibility, this setup delivers top-tier clarity for planetary, solar, and deep-space target capture.
