Celestron C925 XLT Schmidt Cassegrain Optical Tube Assembly

Celestron Schmidt-Cassegrain Optical Tube Assemblies (OTA) are 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 bar as used on CG-5 mount 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 1/4 is Celestron’s first new Schmidt-Cassegrain optical system in over a decade. The new 9.25” Schmidt-Cassegrain features a precision optical system with 2350mm focal length (f/10) and comes standard with Celestron’s StarBright® XLT coatings at no extra cost.

Is this OTA Fastar / Hyperstar Compatible?
For this telescope what would I need to buy to be able to use 2" eyepieces? About what would it cost and would it be worth the money and aggravation that might be involved? Thank you!
Is this OTA compatible with the mount SkyWatcher AZ-EQ6 Goto?
