The Celestron 11-inch RASA combines speed with performance. Based on the original Schmidt camera design, the RASA optical tube offers significant advantages by providing a short focal length for a relatively large aperture. Experience essentially perfect imaging with this Celestron astrograph.
The Celestron RASA offers an exceptionally sharp 43.3 mm image circle that accommodates large sensors. Its large image circle creates an exceptional wide-field, allowing you to fill even the largest imaging chips with edge-to-edge pinpoint stars with minimal vignetting.
Fast Astrograph Optical System
Its short focal length provides a wide-field f/2.2 system, offering the advantage of better apparent tracking. With only a 620 mm focal length, exposure times are also greatly reduced when compared to traditional Schmidt Cassegrain telescopes. You'll be capturing better images in a fraction of the time, without the need of an autoguider!
Excellent Clarity and Flat Field of View
The Rowe-Ackermann scopes are perfect for creating giant night-sky mosaics, surveying, and comet hunting. Designed with 4-element rare-earth glass, images are free of false color, coma, and field curvature. Optical quality this excellent has been unheard of in astrographs within this price range.

Designed for Peak Performance
Engineered as a complete astro-imaging system, every component of the Rowe-Ackermann Schmidt Astrograph is optimized for peak performance with DSLR and astronomical CCD cameras. Down to the thickness of the glass used in the included fully multi-coated optical window or an optional imaging filter, every component of the system has been taken into careful consideration to work together seamlessly.
