The RASA 11 V2 is an ultra-fast f/2.2 wide-field astrograph that allows for shorter exposure times compared to traditional f/10 systems without sacrificing resolution. With a 43.3mm optimized image circle and 4-element rare-earth glass optics, it delivers pinpoint stars and images free of false color, coma, and field curvature. The 620mm focal length combined with the Ultra-Stable Focus System makes this instrument ideal for wide-field imaging and large sky mosaics. An integrated 12V DC MagLev fan provides rapid cooling and optimal optical performance.
