Technical Features for Celestron 11" RASA - OTA Only

The Celestron RASA is a 11-inch Rowe-Ackermann Schmidt astrograph with rare-earth glass for images free of false color, coma, and field curvature. It features fast, wide-field f/2.2 system with 2 advantages, better apparent tracking and shorter exposures. The 43.3mm optimized image circle maintains pinpoint stars to the far corners of even the largest astroimaging sensors, while the usable field extends even further to 52 mm for larger format sensors.

The Celestron RASA has custom engineered linear brass focuser bearing that reduces image shift, while dual-speed 10:1 FeatherTouch Micro Focus Knob provides the most precise focusing. The quiet, high-output 12V MagLev fan reduces cooldown time and blocks dust.
