Celestron CGEM-II Equatorial "GoTo" Mount
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") securely and vibration free which is ideal for both imaging and visual observing. With a whole new saddle design and more ergonomic design, the improvements are just waiting for you to benefit from them.
Ergonomic Design - The Celestrom CGEM-II mount was designed to be ergonomically friendly with large Altitude and Azimuth adjustment knobs for quick and easy polar alignment adjustment. These knobs have been redesigned in the CGEM-II to be easier and more comfortable to grip as well. The internal RA and DEC motor wiring provides 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 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 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.
Versatility- The Celestrom CGEM-II series implements a new dual saddle design that greatly expands your options for what telescopes to use in conjunction with it. It permits both Vixen/CG-5 and Losmandy/CGE dovetails on the saddle.

Product QuestionsSince the CGEM II Mount "..uses any bright star for a quick and accurate Polar alignment", What do I get better than that if I add the "StarSense autoAlign."Question by: Dick on Jun 6, 2017 5:35:00 PMHello and thanks for your inquiry. The Star Sense does not do polar alignment. Adding the starsense increases your overall tracking and pointing performance but the polar alignment accuracy is determined by the user. Check page 16 of the star sens manual. http://www.celestron.com/media/1317936/94005_starsense_autoalign_manual_february2016.pdfAnswer by: Anthony White (Admin) on Jun 7, 2017 1:03:00 PM
