The CGE Pro 925 HD Telescope features EdgeHD coatings in a 9.25" OTA, specially designed from Celestron. The optical technology is highly appropriate for various types of astrophotography. The telescope is highly oriented for those advanced longtime and highly committed amateur astronomers due to its combination of the one and famous CGE Pro Computerized Mount and a fabulous 9.25" aperture Schmidt based optical tube with Celestron's own EdgeHD optics. The EdgeHD optical system takes it a step further than the traditional Schmidt-Cassegrain system to make sure that stars appear pinpoint through the whole field of view (including the edges) on a flat focal plane three times flatter than the standard Schmidt-Cassegrain design. This helps tremendously with getting good quality astrophotography images even when using some of the largest chip designs.
The CGE Pro Equatorial Mount is a well built mount for both astrophotography and visual use because of its easy adjustment of altitude and azimuth. It has a payload of 90 pounds. The mount uses Celestron's All-Star polar alignment, a feature that allows the observer to precisely align their mount to the north celestial pole for accurate alignment and tracking of celestial objects. It is a very straightforward process. The observer aligns the telescope to two bright stars and then points to a star as if the mount was polar aligned. Therefore, the user can now precisely and accurately align their mount with the north celestial pole. It is NOT recommended that you use Polaris as a star since it is too close the the NCP.
CGE Pro Mount Features:
- Payload Capacity - 90 Ib payload capacity.
- All-Star Polar Alignment - Precisely align your mount with the NCP by choosing a bright alignment star.
- No-Tool Polar Alignment - Large hand knobs for adjusting altitude and azimuth
- Meridian Tracking - Track 20° past the meridian, the clearest and darkest section of the night sky
- Faster Slew Speed - Maximum slew rate of 5°/ per second - improved with new motors and gears
- Accuracy - Very accurate tracking of celestial objects
- Pointing - NexStar's advanced pointing features can result in a 1 arc minute pointing accuracy of stars
- Tracking - +/- 5 arc second tracking accuracy and further reduced with PPEC.
- Mount Calibration - NexStar will compensate for the inaccuracies of the mount.

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.
