Used Celestron 11" SCT OTA with CGE Dovetail and Fastar - Sold

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 coatings. 

Weighing only 27.5 lbs., this telescope is still portable enough to be taken to dark skies, but it has 89% more light gathering power than an 8" telescope. Using an f/6.3 Focal Reducer makes it usable with a wide variety of CCD cameras. As a visual instrument you can search for all of the Messier Catalog, NGC, IC and Caldwell objects. Turn this scope to the planets and see amazing detail on the surface of Jupiter; see Cassinis 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.
