Computerized Mount Features
All-new design. Sturdier and more rigid with quicker dampening time Increased load capacity to 55 lbs. Improved motors provide more torque, better slewing and tracking under heavy loads Heavy Duty belt-drive system minimizes backlash while providing smooth motor operation under heavy loads Spring-loaded brass worm wheel and stainless steel worm gear reduce friction and provide optimum gear mesh Internal cabling for worry-free remote operation. Power input and
accessory ports remain stationary while the mount slews to avoid snags Internal hard stops for both axes prevents cable tension and tripod strike Internal optical sensors on both axes for simple and safe remote operation Home sensors allow the mount to always start in the index position regardless of orientation before a power reset Limit sensors automatically shut off slewing or tracking before reaching the hard stop fail safe Brand new control software developed in conjunction with PlaneWave
Instruments for professional level control operation and imaging Software includes multi-point mount modeling for extremely precise
pointing accuracy and many more additional features for remote
astroimaging Wider tripod stance for improved stability Adjustable EQ head position to optimize center of gravity over the tripod and fully utilize the increased 3º-65º latitude range Dual-fit CG-5/Vixen and CGE/Losmandy dovetail saddle

Introducing the EdgeHD Telescope Series, Celestron’s new flagship
telescope line... fused to their CGX Mount, the newest and greatest in
German Equatorial mounts. With a proven telescope to mount atop it, the
CGX is sure to provide you with some of the finest astronomical
experiences you've had to date!
The Edge HD is Celestron’s latest innovation that will surely be the
system of choice for the serious astro-imagers. The new Edge High
Definition telescope series features an Aplanatic Schmidt optical system
that produces pinpoint star images all the way to the edge of the
field. Some optical systems currently on the market may produce coma
free images. But there is a difference.... the optical difference. Not
only is the Celestron Edge 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 astro photograph.
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.
The Celestron CGX Mount is an innovative new design that improves on it's predesscors in every imaginable way.
Ergonomic Design - The Celestrom CGX mount is incredibly ergonomic, from the convenient carrying handles to the easy to use and turn knobs.
Splendid Engineering- This mount boasts drastically
reduced backlash and improved stability. Incredibly rigid, this mount
also boasts an improved motor system that greatly boosts the provided
torque. It's simply superior to it's predecessors in every way.
Innovation - The Celestron CGX series boasts internal cabling
that utterly bypasses the issue of cable twisting or tangling by letting
you route all your own power supply and accessory cables into a
convenient port on a part of the mount that moves- from which they enter
into the mount, utterly contained, and reach everywhere they need to on
the inside without any tangling issues. Neat and clean!
Performance - For objects near the Meridian (imaginary line
passing from North to South), the Celestron CGX mount will track a full
20 degrees past the Meridian for uninterrupted imaging through the most
ideal part of the sky. The CGX mount has a robust database with over
40,000 objects, utilizing a top quality Nexstar hand controller.
Celestron's bleeding edge new CGX mount is the current pinnacle of
German Equatorial Mount Engineering. Boasting a wide range of new and
improved features, this mount is simply top quality. It's just plain
better than it's competition and predecessors.
