Description
CELESTRON C11-A XLT (CG-5) OPTICAL TUBE ASSEMBLY
Outfitted with an over-sized aperture, long effective focal length, and their proprietary StarBright XLT optical coatings, the Celestron Celestron C11-A XLT f/10 Schmidt-Cassegrain Telescope provides power and portability. The coating system consists of anti-reflection coatings on the corrector plate, highly reflective index mirror coatings, and low-absorption/high-transmission glass components to ensure that the maximum amount of light is gathered and transmitted to the user’s eye.
The Celestron C11-A XLT ensures bright and clear high-contrast images with accurate color rendition across the entire visual spectrum without visible distortion at the edges. Celestron includes a standard 1.25″ visual back to accept eyepieces and accessories such as the 40mm eyepiece and 90° diagonal supplied with the optical tube assembly (OTA). This OTA is offered here without a mount or tripod for users who already have a support system – just ensure the mount’s payload capacity exceeds 27.5 pounds to safely carry the weight, and has a Vixen-style saddle to match the OTA’s CG-5 mounting plate.
