Celestron Astrographs

Celestron astrographs are telescopes built first for imaging, with a flat, fast field across a camera sensor. Most are RASA (Rowe-Ackermann Schmidt Astrograph) designs, from the RASA 6 and RASA 8 to the RASA 11 V2 and 36 cm RASA, sold as optical tubes or in kits on Advanced VX, CGEM II, CGX and CGX-L mounts.

Their f/2 class focal ratio collects light quickly for nebulae and galaxies. The Origin Mark II is an all-in-one smart home observatory that captures and processes images automatically.
