The Celestron C9.25 is an unusual size with its 9.25" aperture and 2350 mm focal length, considered by many to be the ideal balance—not too big, not too small. This rugged aluminum optical tube is only 22 inches long and weighs just 20 pounds, making it easy to transport and set up. It is equipped with Celestron's patented StarBright XLT optical coatings, which visibly increase contrast and light transmission for brighter deep space images and shorter exposure times, allowing you to discern subtle details while viewing the Moon and planets as well as faint galaxies and nebulae. The Celestron C9.25 can be mounted on a multitude of computerized telescope mounts thanks to its CGEM-style dovetail bar, making it exceptionally versatile for both visual astronomy and astrophotography applications.
