This 9.25" aperture optical tube assembly (OTA) is one the most popular size of Celestron's Schmidt-Cassegrain range and also one its most well regarded too. The telescope is not too large or too heavy to handle meaning that it can be used on a wide range of popular mid-range mounts such as Celestron's Advanced VX.
The C9.25 features Celestron's StarBright XLT coatings on the corrector plate for maximum light transmission. The telescope has a 2350mm focal length (f/10) making it a good overall performer on a range of celestial objects.
The telescope comes with a star diagonal for more comfortable viewing of high altitude objects and a 25mm Plossl eyepiece which gives 94x magnification. A 6x30 finderscope to help locate objects completes the package.
There are two dovetail bar versions of the C9.25 available - a CG-5/Vixen style and a wider CGE style. Both models are identical optically and with what is included in each package.
