Product Details

  • This Celestron 203 mm (8-inch) Schmidt-Cassegrain Optical Tube Assembly (OTA) with CGE Mount 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.

    Besides seeing all of the Messier Catalog objects, you can also see hundreds of other, less famous, but equally interesting 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. 

    This 8-inch Schmidt-Cassegrain features a precision optical system with a 2032 mm focal length, a focal ratio of f/10, and comes standard with Celestron's StarBright XLT coatings at no extra cost.

    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.
