The Celestron 234.95 mm (9.25 Inch) Schmidt-Cassegrain Optical Tube Assembly (OTA) with CG-5 Mount Plate is available individually to be used with your favorite mount. Each OTA is made to the same exacting standards as those used on all their high-quality telescopes. All optical surfaces are coated with StarBright XLT coatings. These tube assemblies are equipped with the same dovetail mounting plates as used on CG-5 mounts for easy attachment to a variety of popular mounts (see below). 

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.

The Celestron C9.25 Inch is Celestron's first new Schmidt-Cassegrain optical system in over a decade. The new 9.25 Inch Schmidt-Cassegrain features a precision optical system with a 2350mm focal length, a focal ratio of f/10, and comes standard with Celestron's StarBright XLT coatings at no extra cost.

What's more- you have Celestron's guarantee of uncompromising quality backed up with a Two Year warranty. Celestron warrants your telescope to be free from defects in materials and workmanship for two years. Celestron will repair or replace such product or part thereof which, upon inspection by Celestron, is found to be defective in materials or workmanship.

OPT Product Number: CE-91025-XLT

Please Note: This optical tube assembly will fit on the Celestron CG-5 and Advanced VX mount as well as the Meade LXD55, the older style Losmandy GM-8, and some Vixen mounts. It will not attach to mounts that accept a 3 Inch dovetail, such as the CGE, G-11, Paramount, or newer GM-8. If you are unsure, please give us a call before you buy. Thanks!

Celestron C9.25 Telescope

It is an excellent telescope with great optics. It arrived perfectly collimated, and I have been imaging the Moon with it. It produces terrific images and with a 2X Barlow shows great detail. There is very little mirror shift with focusing. It is actually lighter in weight then the 6” refractor I had been using before. The only concern is that the finder is barely adequate, but I have replaced it with a good 50mm finder with right angle eyepiece holder. The scope is excellent and comes at a very good price for the quality of the optics. I am really glad that I bought the telescope.

Very good star test - better than my first 9.25 (circa 2000). Minor collimation touch-up needed.

Celestron 9.25

Optically excellent. Superb planetary performer. One of the best star tests I have seen in an SCT.
