Product Details

  • The Celestron C9.25-inch Schmidt-Cassegrain OTA with CGE Mount Plate is available individually to be used with your favorite mount. Each OTA is made to the same exact standards as those used on all their high-quality telescopes. All of its optical surfaces are coated with StarBright XLT coatings. These tube assemblies are equipped with the same dovetail mounting bar as used on the CGE Pro or CGEM series for easy attachment to a variety of popular mounts.

    Besides seeing all of the Messier Catalog objects, you can also see hundreds of other, less famous, but equally interesting NGC, IC, and Caldwell objects. Turn this scope to the planets and see amazing detail on the surface of Jupiter; see Cassini's Division in the rings of Saturn, and resolve details on the surface of Mars. Even the distant Uranus, Neptune, and Pluto are within your reach.
