I've wanted a Celestron OTA for quite some time. Having started with smaller scopes (a 5" Maksutov) and an 8" Dobsonian, the next step was to acquire the Celestron. The wait was worth t - this is a great scope.

This telescope replaced my heavier 12" SCT and is more portable when used with my German Equatorial Mount. The Owl nebula Messier 97 was easily seen with this telescope and a UHC filter from my city location. Detail on the planet Saturn was excellent.

The 9.25 is a classic. Can't go wrong.
