8-Inch Schmidt-Cassegrain OTA for CGE Mounts

This optical tube assembly uses an 8-inch aperture with Starbright XLT coatings to gather light for detailed celestial viewing. It ships with a 25mm eyepiece and a 1.25-inch star diagonal for immediate use. A 6x30mm finderscope and dovetail slide bar complete the package for precise alignment and secure mounting.

Observers Wanting a Complete CGE-Compatible Package

The tube suits astronomers who want a ready-to-observe system that attaches directly to a CGE dovetail saddle. Buyers who need a different mount interface or who prefer a separate guide scope arrangement should look at other configurations.

8-Inch Aperture with Starbright XLT Coatings

The 8-inch aperture defines the light-gathering capability and resolution limit for planetary and deep-sky targets. Starbright XLT coatings increase transmission across the optical path for brighter, higher-contrast images. This specification determines whether the tube meets your observing goals.

Questions about this item

Which mount dovetail does the C8-A optical tube require?

The tube ships with a dovetail slide bar made for CGE mounts, so it attaches directly to any Celestron CGE or compatible equatorial mount.

Will my existing 1.25" eyepieces and diagonals work with the included accessories?

Yes, the supplied 25 mm eyepiece and star diagonal both use the standard 1.25" barrel, so any 1.25" eyepiece, filter or diagonal you already own will fit without adapters.

How can I verify the Starbright XLT coatings are performing after first light?

Point the telescope at a bright star; the image should appear crisp with minimal scattered light and strong contrast between the star and the dark background, confirming the multi-layer mirror and corrector coatings are transmitting efficiently.
