The CGX-L 1100 Rowe-Ackermann Schmidt Astrograph Equatorial Telescope (CGX-L 11" RASA) sets a new standard in astroimaging systems at an extremely affordable price. The CGX-L 11" RASA telescope is an excellent advanced-level imaging setup. The Rowe-Ackermann Schmidt Astrograph (RASA) produces images in a fraction of the time compared to other optical tubes. The CGX-L mount is designed to provide superior performance for larger telescopes while taking advantage of Celestron's most advanced technologies: All-Star Polar Alignment, Celestron PWI telescope control software, Starry Night Special Edition software, SkyAlign, and permanently programmable periodic error correction (PPEC). If you're an experienced imager, you'll love taking this mount to a dark sky site and enjoying all the conveniences of a larger observatory mount. Rowe-Ackermann Schmidt Astrograph Features Capturing impressive deep-sky astroimages is easier than ever with Celestron's Rowe-Ackermann Schmidt Astrograph (RASA) V2, the perfect companion to today's top DSLR or astronomical CCD cameras. This fast, wide-field f/2.2 system allows for shorter exposure times compared to traditional f/10 astroimaging, without sacrificing resolution. Because shorter sub-exposure times are possible, your equatorial mount won't need to accurately track over extended periods. The short focal length also lessens equatorial tracking demands. In many cases, autoguiding will not be required. RASA
