- Built-in polar alignment program to polar align on any star in the sky
- Longer clutch levers to make tightening and loosening of clutches easier
- Custom database lists of all the most famous deep-sky objects by name and catalog number
- Solar System alignment method allows to view the moon and planets during the day
- Permanent Programmable Periodic Error Correction (PEC) corrects periodic tracking errors inherent to all worm drives
- Custom Rate 9 feature allows to set maximum slew rate
- Tandem mode allows to star align the mount even when positioned for tandem scope use
- RS-232 communication port on hand control to control the telescope via a personal computer
- Includes NexRemote telescope control software, for advanced control of telescope via computer

Now let's talk about Celestron quality...
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-inches) 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 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. Furthermore, the new mount model is equipped with a dual saddle capable of mounting both predominant kinds of Dovetail.
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 next level of GEM mounting, an all-around improvement to their previous CGEM model with more to it than just a new paint job and a saddle!
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.
Included Technology
All-Star Polar Alignment
Get ready for a night of astroimaging with your mount faster than previously thought possible with All-Star Polar Alignment. This innovative software solves the time-consuming problem of trying to pinpoint the North Celestial Pole.
EdgeHD Optics
Celestron’s aplanatic EdgeHD optics revolutionized astroimaging. This award-winning optical system reduces visual defects like field curvature and coma, creating an ultra-flat field for pinpoint stars all the way to the edge of today’s largest imaging sensors.
Compatible Technology
LiFePO4
The new Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries, great for those Astronomers on the go.
Starsense Technology
Celestron’s patented StarSense Technology makes it easier than ever to locate objects in the night sky, even if you’ve never used a telescope before. Turn it on and push ‘Align.’ In about three minutes, you’re ready to observe!
WiFi
WiFi technology encircles the globe in a web of connectivity, knowledge, and information. Now, Celestron is using that same technology to allow stargazers to connect to the night sky and enhance their experience of the cosmos in fun and unique ways.
