The CGEM-II 1100 Telescope by Celestron is a 279 mm (11-inch) Aperture Schmidt Cassegrain Telescope on a CGE Mount. With a telescope capable of gathering 1600X more light than the human eye, the precise f/10 optics of the Celestron C11 SCT offer up an incredible 0.47 arc seconds of resolution spread out over a 0.71 degrees angular field of view. With a limiting magnitude factor of 14.7 and a practical magnification limit of 661x, it delivers remarkable planetary and lunar views. With a low-end magnification limit of 40x, just add a wide field eyepiece, or open both eyes wide with Celestron Stereo Binocular Viewers and enjoy panoramic vistas of extended nebulae and sweep the heavens for every last photon! The Celestron CGEM-II is a great tool for astrophotography, too! It can be as simple as adding a Celestron NexImage Solar System Imager to the CGEM-II-1100, or even just adapting a digital camera!
