Celestron's CGE Pro 1100HD Telescope includes both the 11" EdgeHD Optical Tube Assembly along with the CGE Pro Equatorial Mount. The 11" HD OTA has 89% more light gathering than the 8" EdgeHD but still is very mobile. Astro-imaging should definitely be taken advantage of with the CGE Pro's outstanding balancing, unlimited space for the telescope tube for mounting a camera, and complete access to the night sky. Celestron's EdgeHD optical system is a step up from the ordinary Schmidt-Cassegrain System by improving high definition for wide field which makes these telescopes wonderful for astrophotography.
Equatorial mounts are usually recommended for astro-imaging because they're easy to balance and adjust with counterweights. The CGE Pro Equatorial Mount uses the AllStar alignment feature from Celestron which is a polar alignment based system in which the observer with align the mount to the north Celestial pole by selecting a star to align to from the Hand Controller's database and then Sync the star by selecting "Polar Align" and asking the observer center it in the eyepiece. The CGE Pro Equatorial Mount will then slew to the position where the star should be if the mount was aligned properly which will now allow the observer to adjust altitude and azimuth to precisely align the mount with the NCP. It is not recommended that you use Polaris since it is too close to the NCP. Once this alignment is completed, the database of objects to slew to is enormous! The viewer can slew to all the available Messier objects, NGC, IC, and Caldwell objects. There is no aberration with the EdgeHD optics, to astrophotographers can use their CCD or DSLR Camera and get pinpoint sharp images. If someone is using a very large CCD sensor, they'll still get sharp images.
- Increased Payload Capacity - Up to 90 pounds!
- All Star Polar Alignment - Use any star to get the mount aligned with the north celestial pole
- No-Tool Polar Alignment - Large hand knobs adjusting altitude and azimuth
- Meridian Tracking - Maximum tracking of up to 20° past the meridian
- Faster Slew Speed - New improved motors and gears increase slew speed of up to 5° per second!
- Accuracy - Excellent tracking and location of celestial objects!
- Pointing - With the use of Sync and calibration stars, 1 arc minute of accuracy can be achieved!
- Tracking - +/- 5 arc second tracking accuracy with unguided periodic error and further reduced at PEC

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.
