The Celestron RASA 36 V2 OTA is a professional-grade astrograph featuring a massive 36cm f/2.2 optical system designed specifically for wide-field astrophotography and scientific imaging. With its patented Rowe-Ackermann Schmidt design, 4-element ED glass optics, and extended 400-900nm spectral response, it delivers flat-field images free of coma and astigmatism across the entire 60mm image circle. The new Ultra-Stable Focus System with precision linear ball bearing eliminates focus shift and mirror flop during long exposures, while the integrated 12V DC MagLev fan ensures rapid cooling for optimal thermal performance during imaging sessions.
