Advanced VX 800 Rowe-Ackermann Schmidt Astrograph (RASA)

The 8" RASA is an astrograph designed specifically for deep-sky astronomical imaging, using a prime focus focal plane to achieve its super-fast F/2.0 focal ratio. Weighing just 17 pounds, it is easy to transport to remote dark sky locations, and its fast focal ratio and patented optical design allow astrophotographers to produce sharp, detailed images and in many cases skip the autoguider completely. All refractive optical surfaces are coated with StarBright XLT coatings while the primary mirror uses enhanced aluminum coatings, maintaining high light transmission through the entire optical system.
