Overview
The Celestron CGX-L 1100 EdgeHD is a substantial investment aimed at astronomers who are ready to move beyond casual observing into dedicated astrophotography or high-magnification planetary work. The 11-inch (279.4mm) aperture collects serious amounts of light, making faint galaxies, nebulae, and globular clusters genuinely accessible rather than just theoretically visible. The EdgeHD optical design corrects for field curvature, which matters most when pairing this scope with a camera sensor, since stars stay sharp and round across the entire frame rather than bloating at the edges.
The f/10 focal ratio gives you a long focal length well suited to planetary detail and tight galaxy cores, though wide-field imaging will require a focal reducer. The CGX-L mount handles up to 75 lbs, which means you have room to add cameras, guide scopes, and accessories without stressing the system. GoTo and tracking are handled through the NexStar+ hand controller alongside PWI Software, giving you both manual control and computer-based session planning.
One honest note: with only two Amazon reviews averaging 1.0 out of 5, prospective buyers should research recent user experiences carefully before committing at this price point.

Key Features
- The 11-inch aperture resolves fine planetary detail and pulls in genuinely faint deep-sky objects under dark skies
- EdgeHD optics flatten the focal plane, keeping stars sharp edge to edge, which is essential for astrophotography with full-frame or large sensors
- The CGX-L mount supports up to 75 lbs, leaving ample capacity for cameras, guide equipment, and counterweights
- GoTo functionality with a large onboard object database simplifies finding targets, especially useful when learning the sky
- PWI Software allows computer control and session planning, useful for remote or automated imaging setups
- Maximum useful magnification of 660x makes this capable for serious planetary and lunar observation
- The f/10 focal ratio is well matched to planetary work but will require a focal reducer for wider deep-sky imaging

I had ordered this to arrive just in time to see Uranus at opposition on 10/19. When the packages arrived that day, I opened them to find that I was sent just the CGX-L mount. So, disappointed that I missed opposition, I called the seller and requested the rest of my product (the OTA) be sent to me....
What I dislike: 1) Customer service is horrible. I had assembled and installed the mount on a pier in my observatory and I had issues with the polar alignment. This is a classic catch 20 20 situation. Ideally polar alignment should be done without the mount being loaded 2) Anyway, when I attempted t...
