Celestron 8" Schmidt-Cassegrain OTA with CGE Mount Plate

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 2032 mm focal length, a focal ratio of f/10, and comes standard with Celestron's StarBright XLT coatings at no extra cost.

What's more- you have Celestron's guarantee of uncompromising quality backed-up with a Two Year warranty. 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.

Questions & Answers

  • Can a 2" visual back be installed ? How much trouble and expense would this job entail ? Thanks for you time, Sincerely, John R Willis

    This telescope can easily be converted to 2" accessories. The TPO part OS-ASCT2 or the TeleVue part TE-ACC-0003 will thread onto the rear 2" threads and allow the use of 2" accessories to be slid into place.

  • is the celestron 8 Schmidt fully automatic? does it come with it own mount or do I have to purchase one

    This optical tube is just the telescope tube with no mount or tripod included. You could attach this to any mount that accepts a 3" Losmandy/CGE style dovetail plate. but the mount would need to be purchased seperately. Celestron does sell packages with

  • Will this "8" OTA mount onto a SLT130 as is or do i need a different mount or different dovetail also would a "6" OTA fit on same mount?

    An 8" OTA will be to heavy for the Celestron SLT mount.

  • What is the advantage for the user in purchasing the ZWO ASI 1600 Monochrome kit with 31 or 36 mm filters vs.1.25" filters? Is there a risk of vignetting with the smaller filter sets?

    The ZWO ASI1600 has a chip diagonal size of 21.9mm meaning that you will suffer no vingetting with either filter size. The larger filter option is available for customers who already own 36mm filters and do not want to have to replace their existing set.

  • Is this OTA too heavy for the Orion Astroview GEM? It's rated for 12 pounds, just barely less than the C8 weighs. I know it might be marginal, but would it work even for a short while, until I can afford the upgrade to a better Go-To mount? I have a C6 no

    Unfortunately, the AstroView will not carry an 8"SCT. You would be better to upgrade the mount first and use the 6" until you can upgrade the optical tube to a larger scope later.
