The CGEM-II 925 EdgeHD by Celestron is a 235 mm (9.25-inch) aperture corrected Schmidt-Cassegrain telescope with a CGEM-II Mount.

The Celestron Edge is coma-free, but it also has a built-in field flattener to ensure sharp focus all the way to the edge of the field, producing true Astrograph quality images. This results in pinpoint, High Definition star images throughout your astrophotographs.

Celestron's Special Features 

The Celestron CGEM-II mount has a fresh, attractive, bold appearance and is capable of carrying Celestron's higher-end SCT optical tubes (up to 11-inch) securely and vibration free which is ideal for both imaging and visual observing.

Ergonomic Design - The Celestron CGEM-II mount 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 provide a clean look and an easy and trouble-free set-up.

Innovation - The Celestron CGEM-II 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-II, sure to please astro-imagers, 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. Furthermore, the CGEM-II now has a dual-saddle design that permits you to use both kinds of Dovetail Plate with the mount!

Performance - For objects near the Meridian (imaginary line passing from North to South), the Celestron CGEM-II mount will track well past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGEM-II mount has a robust database with over 40,000 objects, 400 user-defined programmable objects and enhanced information on over 200 objects.

Celestron's CGEM-II mount is the perfect fit between the Advanced Series and CGE Series. Offering the portability of the Advanced Series and the precision of the CGE.

Superior mount performance combined with superior edge performance not only creates rounder, more pleasing stars but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. When it comes to the Celestron HD series coupled with Celestron's StarBright XLT coating group on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum... It's a vision you'll never forget.
