Comparison
The Celestron CGX-L 1100 EdgeHD is the clear winner for anyone serious about astronomy. While the Celestron CGX 800 HD scores identically for beginner use and portability, it falls dramatically short in every observational category that matters. The CGX-L 1100 EdgeHD delivers nearly triple the deep sky score (64 versus 20) and more than three times the planetary performance (62 versus 18), making it far superior for actual observation.
The single most important differentiator is aperture; the CGX-L 1100 EdgeHD's 279mm mirror versus the CGX 800 HD's 203mm aperture fundamentally determines light-gathering ability and resolving power. The Celestron CGX 800 HD suits only budget-conscious beginners who accept severe compromises in viewing quality and don't mind the telescope becoming a limitation quickly. The Celestron CGX-L 1100 EdgeHD belongs with intermediate to advanced amateur astronomers and those pursuing serious astrophotography or planetary observation.
If your budget allows for the additional $3000 investment, the CGX-L 1100 EdgeHD will deliver substantially more rewarding views and far greater longevity in your observing hobby. The CGX 800 HD represents poor value given how completely the larger scope outperforms it.
