The Celestron 9.25" EdgeHD offers ample aperture for capturing the night sky and deep sky objects. Paired with the ergonomically designed CGEMII, which is capable of a 40 pound load capacity, you can use large or heavy cameras and guiding systems without worrying about stressing the mount. The EdgeHD optical system takes all of the compact power popularized by the SCT and combines it with an improved high definition optical system for wide field, astrograph quality images.

Product Description

Celestron 9.25" EdgeHD Telescope with CGEM II Equatorial Mount

The Celestron EdgeHD 925 is a catadioptric based optical tube assembly with the EdgeHD optical system to reduce coma. This makes it outstanding for both visual astronomy and astrophotography and is capable of imaging a wide variety of celestial objects ranging from planets to distant galaxy clusters. With the addition of the StarBright XLT™ coatings by Celestron, excellent and efficient light transmission is realized. Since most Schmidt-Cassegrain designs normally have a default focal ratio of f/10 but can be reduced by using the Fastar™ system of removable secondary mirrors to create a blazing- fast focal ratio of f/2 for wide field and fast astrophotography with most deep sky objects. This is a step up from the regular Schmidt-Cassegrain design!

Celestron - CGEM II Equatorial Mount

Celestron has updated the ever popular CGEM mount.  The Celestron CGEM II equatorial mount includes new ergonomic design features, the All Star alignment procedure, and legendary Celestron mount performance.  An instrument capacity of up to 40 pounds allows this mount to carry an 11" optical tube with ease.  

The CGEM II includes extra large Altitude and Azimuth adjustment knobs so you can polar align easily, even in cold weather while wearing gloves. A dual saddle plate will accept both V and D series dovetails. Internal mount wiring keeps the exterior of your mount free from cables and prevents cable tangling or wrapping. Celestron's AllStar polar alignment procedure allows you to use any star in the night sky whether the celestial pole can be seen or not.  The results are accurate polar alignment, tracking, and pointing.  The Celestron CGEM II will track far beyond the meridian for uninterrupted tracking.  Permanent Periodic Error Correction (PEC) will train the mount's worm gears over time to remove natural errors that occur during tracking.  

Included with the Celestron CGEMII is a USB hand controller with over 40,000 objects and 100 user-defined objects plus enhanced information on over 200 objects.  The mount's tripod include height marked adjustable legs so you can quickly setup.   If you were considering a Celestron AVX mount but worried it would be too lightweight, the CGEM II is a perfect fit providing a stable base for larger optical tubes and heavier imaging systems.
