Product Description

CELESTRON  •  C11A -XLT 11" Optical Tube Assembly (OTA)  •  91036 - XLT

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 (optional) 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 (like beautiful M13), 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. 

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 the CGE Pro or CGEM series for easy attachment to a variety of popular mounts  such as the Celestron CGE Pro or CGEM, the Losmandy G-11 and newer GM-8, Software Bisque's Paramount, and mounts by AstroPhysics.

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.
