Celestron RASA Astrographs

Celestron RASA (Rowe-Ackermann Schmidt Astrograph) telescopes are fast prime-focus astrographs: the camera sits in front of the corrector plate, giving focal ratios around f/2 and a flat, wide field. The line covers the RASA 6, RASA 8, RASA 11 and the 36 cm RASA, as tubes or in kits on Advanced VX, CGEM II, CGX and CGX-L mounts.

Accessories include Canon and Sony mirrorless adapters for the RASA 8, light pollution imaging filters, dovetail accessory bars and a focuser retrofit kit for RASA 11.
