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.
