11" Rowe-Ackermann Schmidt Astrograph (RASA 11) Optical Tube Assembly (CGE Dovetail)

Capturing impressive deep-sky astroimages is easier than ever with Celestron’s new Rowe-Ackermann Schmidt Astrograph, the perfect companion to today’s top DSLR or astronomical CCD cameras. This fast, wide-field f/2.2 system offers two huge advantages over traditional f/10 astroimaging: better apparent tracking and shorter exposures. That means you’ll create better-looking astroimages in a fraction of the time, even without the use of an autoguider. The Rowe-Ackermann Schmidt Astrograph builds on the legacy of Celestron’s Schmidt Camera, which allowed astrophotographers to produce images on film in the 1970s. Today, with CCD sensor sizes as large as film—or larger—the Schmidt Astrograph offers a 43.3 mm optimized image circle to capture pinpoint stars on the largest imaging chips. (Note: We previously published 70 mm which is actually the aperture of the last lens in the telescope. The optical design has not changed). Combine this large image circle with a focal length of just 620 mm an
