The Celestron CGEM II 1100 HD combines Celestron’s acclaimed EdgeHD optical system with the newly redesigned CGEM II computerized equatorial mount, delivering a large-aperture telescope designed for astronomers who want substantial light-gathering capability without giving up portability. With its 11-inch optical system, the CGEM II 1100 HD provides 89% more light-gathering power than an 8-inch telescope and 40% more than the 9.25-inch model. This increased light-gathering capability gives the telescope greater optical capacity for observing celestial objects and taking advantage of darker observing environments. Despite its large optical system, the optical tube assembly weighs only 28 lbs., helping keep the telescope portable enough to be transported to dark-sky locations. This makes it possible to combine the benefits of a large aperture with the flexibility to take the telescope away from a permanent observing location. The EdgeHD optical system is paired with the computerized CGEM II equatorial mount, creating an integrated setup that combines Celestron’s advanced optical design with computerized equatorial support. The result is a telescope configuration built around a substantial 11-inch aperture, while retaining a manageable optical tube weight for transportation. The CGEM II 1100 HD therefore brings together EdgeHD optics, an 11-inch aperture, 89% greater light-gathering power than an 8-inch telescope, 40% more than a 9.25-inch model, and a 28 lb. optical tube assembly. It is a strong choice for astronomers seeking the increased light-gathering capability of a large aperture while still having the flexibility to travel to dark skies.
