Astrozap carries the complete line of 8 in., 11 in., and 36 cm Celestron Rowe-Ackermann Schmidt Astrograph (RASA) telescopes including mounts and tripods and also available as optical tube assemblies only.
Capturing impressive deep-sky astroimages is easier than ever with Celestron’s Rowe-Ackermann Schmidt Astrograph (RASA) telescopes, perfect companions to today’s astronomical imaging 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.
