The Celestron 8" RASA Telescope is an astrophotography telescope that delivers an incredibly fast f/1.97 for shorter exposure times and improved tracking abilities compared to standard telescopes, specifically catered for long exposures. The RASA refers to Rowe-Ackermann Schmidt Cassegrain telescope that was previously only found in high end premium cameras. 

To improve the images from this telescope, the Celestron 8" RASA Astrograph also features rare-earth glass for images with no aberration, field curvature or any other visual flaws. The telescopes also feature custom engineered linear brass focuser bearing that reduces image shift, and its integrated 12V MagLev fan reduces cooldown time while simultaneously blocking dust and air pollutants that interferes with image clarity.
