About the Celestron C14-AF XLT Schmidt-Cassegrain OTA - 14" SCT Optical Tube Assembly...
Celestron Telescope Schmidt-Cassegrain Optical Tube Assemblies (OTA) are available individually to be used with your favorite mount. Each Celestron C14-AF XLT 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 Celestron Telescope tube assemblies are equipped with the same dovetail mounting bar as used on the CGE series for easy attachment to a variety of popular Celestron Telescope Mounts and Tripods. This model is FASTAR compatible.
With over three times the light gathering power of an 8" Celestron Telescope, this observatory-class instrument is Celestron''s largest optical system in its class. The Celestron C14 takes full advantage of the vast database of thousands of NGC and Abell galaxies as well as delivering a new level of detail to all your favorite deep sky objects. Turn this Celestron Telescope 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.
