Celestron CGEM Series Telescopes
Celestron landmark CGEM computerized German equatorial mount is a trusted choice for advanced amateur astronomers. Designed to support optical tubes up to 11 inches, CGEM offers all the top features you'd expect: permanently programmable periodic error correction, All-Star Polar Alignment, and SkyAlign. What's more, Celestron has recently added improved motor drive circuits to CGEM for increased torque. Sturdy 2-inch tripod legs anchor your system for long exposure astroimaging. Or, attach a Fastar lens assembly to your Schmidt-Cassegrain or EdgeHD optical tube and use your CGEM to image at f/2.2.
The CGEM EdgeHD Series combines Celestron's CGEM computerized equatorial mount with our top-of-the-line EdgeHD optical system. With up to 11 inches of aperture, our premium StarBright XLT coatings and diffraction limited performance, CGEM EdgeHD telescopes are designed for the serious astroimager.
Ergonomic Design - CGEM was designed to be ergonomically friendly with large Altitude and Azimuth adjustment knobs for quick and easy polar alignment adjustment. The internal RA and DEC motor wiring provides a clean look and an easy and trouble free set up.
Innovation - The CGEM series has a new innovative Polar alignment procedure called All-Star™ (patent pending). All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment. Another great feature of the CGEM, sure to please astroimagers, is the Permanent Periodic Error Correction (PEC) which will allow users to train out the worm gears periodic errors, while the mount retains the PEC recordings.
Performance - For objects near the Meridian (imaginary line passing from North to South), the CGEM will track well past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGEM mount has a robust database with over 40,000 objects, 400 user defined programmable objects and enhanced information on over 200 objects.
