Celestron CGX Equatorial 800 203mm (8") Computerized Schmidt-Cassegrain Telescope

Celestron CGX Equatorial 800 203mm (8") Computerized Schmidt-Cassegrain Telescope

Due to high demand and global product shortages due to the pandemic, please call for availability.

The Celestron CGX is the culmination of over 8 years of experience the engineering team gained designing the previous generation of mounts. Technologies have advanced, as well as ease-of-use and value.

The new CGX was designed to better support your telescope for both visual and astro-imaging pursuits. Key design goals included a lower profile EQ head providing a more compact and more stable setup; a better drive system, remote operation-friendly with home and limit optical sensors, easier polar alignment adjustments and better cable management. In addition to that, we’ve made mechanical and ergonomic improvements throughout to make the mount sturdier, easier to use, and transport. The CGX is our new Equatorial backbone to support a wide range of telescopes.

Product specifications subject to change. More description coming soon.
