The Celestron CGEM II 925 HD combines Celestron’s acclaimed EdgeHD optical system with the newly redesigned CGEM II computerized equatorial mount, creating a telescope designed specifically for demanding astronomical observation and astroimaging. With over 9 inches of aperture and Celestron’s premium StarBright XLT coatings, the CGEM II 925 HD provides over 1,000 times the light-gathering power of the unaided eye. This substantial light-gathering capability gives the telescope the optical capacity needed for detailed astronomical observation while providing a strong foundation for imaging applications. The EdgeHD optical system is designed to deliver diffraction-limited performance, providing the high level of optical performance needed when resolution and image detail are important. With more resolution than the 800 model while weighing less than the 1100, the CGEM II 925 HD offers a carefully balanced combination of aperture, resolution, and weight. This balance makes the CGEM II 925 HD particularly suited to astroimaging. The combination of EdgeHD optics, StarBright XLT coatings, more than 9 inches of aperture, and the computerized CGEM II equatorial mount provides a capable platform for astronomers focused on capturing detailed astronomical images. The CGEM II 925 HD brings together EdgeHD optical performance, over 9 inches of aperture, more than 1,000× the light-gathering power of the unaided eye, diffraction-limited performance, and a balanced design between the 800 and 1100 models. It is purposefully configured as a high-performance telescope for astroimaging while maintaining a practical balance between optical capability and system weight.
