Celestron 6" f/2.2 Rowe-Ackermann Schmidt Astrograph Telescope (OTA Only)

The Celestron 6" f/2.2 Rowe-Ackermann Schmidt Astrograph Telescope (RASA) is specifically designed for astrophotography and astro-imaging with a large aperture and fast focal ratio. Using three-element rare-earth optical glass lenses ensures accurate color rendition and eliminates aberrations such as coma and field curvatures. The improved StarBright XLT multicoating system, which includes antireflection coatings on the lenses and highly reflective coatings on the mirrors, increases light transmission throughout the entire optical path. An integrated fan reduces cooldown time and provides optimal airflow through the optical tube assembly (OTA) while filtering harmful dust from the interior.
