The Celestron 8" Rowe-Ackermann Schmidt Astrograph (RASA) is a portable astrograph designed to capture spectacular wide-field deep sky images in seconds. With an ultra-fast f/2 focal ratio and 400 mm focal length, it delivers stunning wide-field deep-sky images in record time. The 8" aperture and advanced optical design feature a four-element rare-earth lens group, Schmidt corrector, and StarBright XLT coatings that ensure crisp, coma-free results with excellent color correction. Ideal for color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras, its fast focal ratio and patented optical design allow astrophotographers to produce sharp, detailed images and in many cases skip the autoguider completely.
