The Celestron CGEM II 925 Schmidt-Cassegrain Telescope combines a larger optical system with Celestron’s premium StarBright XLT coated optics and the redesigned CGEM II computerized equatorial mount. Designed as a middle ground between portability and high resolution, the CGEM II 925 provides a capable platform for astronomers who want substantial optical performance without moving to the larger models. Its 9.25-inch aperture and StarBright XLT coatings provide over 1,000 times the light-gathering power of the unaided eye, giving the telescope substantial light-gathering capability for astronomical observation. The larger aperture makes the CGEM II 925 well suited to observers seeking high-resolution views while maintaining a balance between optical capability and portability. The telescope is particularly well suited to long-exposure astrophotography. When paired with optional CCD cameras or photographic equipment, the CGEM II mount provides a solid platform for imaging. Its equatorial design supports applications where stable tracking is important for extended exposures. 

The redesigned CGEM II computerized equatorial mount provides a secure platform for Celestron’s higher-end Schmidt-Cassegrain optical tubes, supporting optical tubes of up to 11 inches. With a 40 lb payload capacity, the mount is designed to carry substantial equipment securely and with reduced vibration, making it suitable for both visual observing and astrophotography. The mount also provides a slew speed of up to 5° per second, allowing you to move rapidly between areas of the sky and point towards celestial objects contained within its database. The computerized system reduces the need to manually locate individual objects, helping you move efficiently from one target to the next. The CGEM II 925 therefore brings together a 9.25-inch Schmidt-Cassegrain optical system, StarBright XLT coatings, high light-gathering capability, computerized equatorial tracking, 40 lb payload capacity, and 5°-per-second slewing in a telescope designed to balance portability with high-resolution astronomical observation.
