CGX 11" RASA V2

11” f/2.2 Rowe-Ackermann Schmidt Astrograph (RASA) V2 uses rare-earth glass for images free of false color, coma, and field curvature Heavy duty CGX computerized equatorial mount with 55-lb payload capacity Description   Optical PerformanceThe RASA 11 V2 features optics with 4-element rare-earth glass for images free of false color and aberrations like coma and field curvature. The optical quality and spot size across the entire image circle are unprecedented for an astrograph in this price range—or even that of a much more expensive instrument. The design also provides minimal vignetting. Advanced FeaturesRASA 11 V2 utilizes the new Ultra-Stable Focus System (USFS). At the heart of this system is a precision linear ball bearing. The bearing serves to minimize focus shift (unwanted lateral motion of the primary mirror during focusing which causes shifting of the image) and mirror flop (movement of the primary mirror when the telescope is pointing to different positions in the
