![]() From a distance, the RASA 8 looks a lot like one of Celestron’s Schmidt-Cassegrain telescopes (SCTs), but as you get closer you’ll notice some significant differences. While Schmidt cameras produced well-corrected stars across a piece of film using a custom film holder that curved the film to match the curved focal plane of the instrument, the RASA design flattens the focal plane with a set of corrective optics located near the camera’s focus point. The RASA 8 is an optical design inspired by the classic Schmidt camera, in which a piece of film is placed at the prime focus of the primary mirror. RASA stands for Rowe-Ackermann Schmidt astrograph, which was a relatively unknown telescope design until. Just as with a fast automobile, though, there’s little tolerance for sloppy driving when it comes to operating this instrument. The Celestron RASA 8 is an 8-inch RASA type telescope. The Celestron RASA 8 is an astrograph that allows you to produce results quickly, and with significant detail. I have some previous experience with fast astrographs and thus was very enthusiastic when the opportunity arose for me to try out Celestron’s new f/2 20-cm (8-inch) Rowe-Ackermann Schmidt Astrograph (RASA 8). FAST OPTICS ARE LIKE FAST CARS: Both are a thrill to experience firsthand. Celestron RASA 8' with EQ6-R and EAGLE is the 203mm Rowe-Ackermann Schmidt astrograph, with computerized equatorial mount and EAGLE that allows you to power, remotely control and install any camera or astrophotography accessory A f/2 astrograph for deep-sky astrophotography with cooled cameras 6,415.00. Some of the advanced features of the Celestron 8' RASA includes mirror locks hold your precise focus. The Celestron CGX 800 RASA TELESCOPE package combines the power of the CGX witht eh fast optics of the RASA8 making this the astrophotography rig of.
