The Celestron CGX-L 1100 Rowe-Ackermann Schmidt Astrograph (CGX-L 11” RASA) delivers an advanced astroimaging system designed for experienced astronomers who demand exceptional imaging performance without the cost and complexity typically associated with large observatory setups. Combining the powerful 11-inch RASA optical system with the capable CGX-L computerized equatorial mount, this system provides a complete platform for serious astrophotography. At the heart of the system is Celestron’s Rowe-Ackermann Schmidt Astrograph (RASA), an optical design engineered to capture detailed astronomical images in a fraction of the time compared with other optical tube designs. This makes the CGX-L 11” RASA an excellent choice for advanced-level imaging and for experienced astrophotographers looking to maximize their time under dark skies. The CGX-L mount is specifically designed to provide robust performance for larger telescopes while incorporating Celestron’s advanced technologies. Features such as All-Star Polar Alignment, Celestron PWI telescope control software, Starry Night Special Edition software, SkyAlign, and permanently programmable periodic error correction (PPEC) provide powerful tools for alignment, control, and precision tracking. For experienced imagers, the CGX-L 11” RASA offers the opportunity to bring sophisticated observatory-style capabilities to a dark-sky location. With its combination of advanced optics, computerized control, and high-performance mounting technology, it provides a powerful platform for exploring and capturing the night sky.
