    Celestron C11-A XLT Schmidt-Cassegrain OTA with CG-5 Dovetail Plate

    The Celestron 279.4 mm (11 Inch) C11-A XLT Schmidt-Cassegrain Optical Tube Adapter (OTA) with CG-5 Dovetail 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 plate as used on the CG-5 series for easy attachment to a variety of popular mounts. 

    Weighing only 27.5 lb, this telescope is still portable enough to be taken to dark skies, but it has 89 percent more light gathering power than an 8 Inch telescope. Using a 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, 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.
