CGEM1100EdgeHD

The scope's optics seem great. The views are fantastic. The mount seems to be more ten stable for visual. The controller quit after about 20min of use. After searching they seem to have trouble with the hand controllers. I rated the scope as very good despite the controller. If they take care of the problem in a timely manner I would raise the rating. If not I would avoid as they would not be trustworthy for other problems.

Great Telescope

By Tsalagi

One of the nicest telescopes on the market.

Celestron CGEM 925 HD combines Celestron's newly designed CGEM Computerized Equatorial mount with its new EdgeHD optical system. With over 9"es of aperture and our premium StarBright XLT coatings, the CGE Pro 925 HD gives you over 1000 times the light gathering power than the unaided eye. Designed to give diffraction limited performace, the CGEM 925 HD has established itself as a premier astro-imaging telescope.
New Optical DesignThe EdgeHD optical system combines all the compact power popularized by the SCT and combines it with an improved high definition optical system for wide field, astrograph quality images. As a visual instrument, EdgeHD optics delivers pin point images even with your widest field eyepiece. You can search for all of the Messier Catalog objects, and see hundreds of other equally interesting NGC, IC and Caldwell objects with amazing clarity. For astroimaging, the EdgeHD optics produces aberration-free images across your favorite CCD or DSLR camera. All EdgeHD optics are designed to produce an extremely flat focal plane precise enough to match the strict tolerances of the largest commercialCCD detectors, allowing all stars to be in tight focus to the very edge of the chip.
Diffraction LimitedSome companies boast that their telescopes give diffraction limited stars in the very center of the field of view . EdgeHD optics not only produce diffraction limited stars on axis, but maintains diffraction limited stars across the entire field of view of many of the most popular astrophotography cameras. Even at the very edge of a full frame camera chip, the EdgeHD 9.25 delivers diffraction limited stars ofonly 1 arc seconds.
The EdgeHD 9.25 optics produces a focal plane almost 9 times flatter than the standard equivalent SCT telescope with diffraction limited stars across the entire Nikon D3 or Canon 5D field of view!

Along with the newly designed optics, the EdgeHD also has re-designed mechanics guaranteed to help you get the maximum performance from your instrument. Features include:
Mirror locks Tohold the mirror in place and reduces image shift during imaging.
Tube vents - Each vent has an integrated 60 micron micro-mesh filter allowing hot air to be released from behind the primary mirror.
Fastar versatility All EdgeHD optical tubes are equipped with a removable secondary mirror for fast f/2CCD imaging. Not only does imaging in the FASTAR configuration allow for exposure times that are 25 times faster than at f/10, but also yields a field of view five times wider. Perfect combination for imaging your favorite wide field objects in a fraction of the time. (FASTAR imaging require a third party lens assembly in place of the secondary mirror).
Axiom Eyepiece - EdgeHD 9.25 optical tubes come with Celestron's top of the line Axiom eyepiece. With a 23 mm focal length and 82 AFOV, you get incredible combination of power and wide field of view. Plus each Axiom eyepiece is optimized to deliver pin point images when used with a flat field telescope.

CGEM Mount
The CGEM mount has a fresh, attractive, bold appearance and is capable of carrying Celestrons higher-end SCT optical tubes (up to 11") securely and vibration free which is ideal for both imaging a

For two years, Celestron will cover repairs or replacement of this product in cases of defective components or damage from normal wear and tear.
