The CGEM™ 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.

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. Celestron's CGEM 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.

Introducing Celestron's New
Aplanatic Schmidt Telescope Design!
• visibly Sharper images
• Superior performance
• Enhanced Mechanical features
• fastar® Compatible EdgeHD is an aplanatic Schmidt telescope designed to produce aberration-free images across a wide visual and photographic
field of view. The optical system was designed to reduce more
than just off-axis star coma, but also to give an astrograph quality
flat focal plane all the way to the edge of the field of view.
True Astrograph Quality
Many optical designs that advertise themselves as "astrograph" quality actually only produce pinpoint stars across a curved focal
plane. While this may be acceptable for visual observing, stars will appear out of focus at the edge when used with a flat chip
sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt Cassegrain
telescope and dramatically flatter than other competing coma-free designs. This guarantees you visibly sharp stars across some of
the largest
CCD chips available today.
Improved Performance
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.
Starbright XLT® Coatings
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.
