![]() ![]() The optical quality and spot size across the entire image circle are unprecedented for an astrograph in this price range-or even that of a much more expensive instrument. ![]() The RASA 11 V2 features optics with 4-element rare-earth glass for images free of false color and aberrations like coma and field curvature. Optical performance for huge sensors with diagonals of up to 52mm wide is still excellent.Ĭombine this large image circle with a focal length of just 620mm and you have an instrument suitable for wide-field imaging, creating huge mosaics of the night sky, surveying, and even comet hunting. Today, with CCD sensor sizes as large as film or larger, the RASA 11 V2 offers a 43.3mm optimized image circle to capture pinpoint stars on the largest imaging chips. RASA 11 V2 builds on the legacy of Celestron’s Schmidt Cameras, which allowed astrophotographers to produce images with much shorter exposure times on film in the 1970s. In many cases, autoguiding will not be required. The short focal length also lessens equatorial tracking demands. Because shorter sub-exposure times are possible, your equatorial mount won’t need to accurately track over extended periods. ![]() This fast, wide-field f/2.2 system allows for shorter exposure times compared to traditional f/10 astroimaging, without sacrificing resolution. Rowe-Ackermann Schmidt Astrograph FeaturesĬapturing 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. 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. 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). 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 1100 Rowe-Ackermann Schmidt Astrograph Equatorial Telescope (CGX-L 11” RASA) sets a new standard in astroimaging systems at an extremely affordable price. ![]()
