Celestron C6-A-XLT f/10 SCT OTA Telescope

The main features of this SCT are the 6-inch aperature, 1500 mm focal length (f/10) aluminum optical tube offering 40 percent more light gathering than a 5-inch telescope. A star diagonal is included along with a 6x30 finder scope to easily find what you're looking for. A 25 mm (60x) eyepiece is included and the eyepiece port allows the use of various 1.25-inch accessories.

This XLT optical tube assembly is equipped with the same dovetail mounting bar as the CG-5 series, making it easily attachable your favorite mount. The C6 optical surfaces are coated with StarBright coatings for a high fidelity image. Has an aperture of 152 mm (6 inches).

Please Note: This optical tube assembly will fit on the Celestron CG-5 and Advanced VX mount as well as the Meade LXD55/75, the older style Losmandy GM-8, and some Vixens. It will not attach to mounts that accept a 3 Inch dovetail, such as the CGE, G-11, Paramount, or newer GM-8. If you are unsure, please give us a call before you buy.

Included Technology

StarBright XLT

One of the most important factors in a telescope is its transmission — the percentage of light that reaches the focal plane. Celestron's proprietary StarBright XLT optical coatings dramatically increase transmission, up to 97.4% on their Schmidt corrector lenses.
