Stargazing ExcellenceThe Perfect Balance of Power and Portability
The Celestron 9.25" Schmidt-Cassegrain Optical Tube Assembly (OTA) provides astronomical observers with the perfect balance between manageable portability and powerful light-gathering capabilities. Featuring a 2350mm focal length (f/10) housed within a 20-pound aluminum body, this Schmidt-Cassegrain telescope offers breathtaking performance for planetary viewing and deep-sky observation.
Advanced Celestial PrecisionEngineered for High Contrast Visuals and Astrophotography
Designed for both high-magnification planetary observation and deep-space astrophotography, the Celestron C9.25 Schmidt-Cassegrain Optical Tube Assembly utilizes Celestron's high-transmission StarBright XLT optical coatings to achieve up to 97.4% light transmission across high-transmission water white glass corrector lenses. Thanks to built-in Fastar technology, astrophotographers can easily remove the secondary mirror and configure their camera at the primary mirror's f/2 focus for high-speed exposure captures. Complete with a CGE/CGEM dovetail rail, 25mm eyepiece, and 6x30 finderscope, this optical tube assembly mounts seamlessly to a wide range of computerized equatorial mounts.
