Overview
The Celestron CPC 1100 is a substantial instrument aimed at amateur astronomers who are ready to move beyond starter equipment. The 279mm Schmidt-Cassegrain optical system delivers a 2800mm focal length, giving you the light-gathering power to resolve globular clusters, track planetary detail, and push into faint galaxies and nebulae that smaller scopes simply cannot reach. The dual fork arm GoTo mount carries a database of over 40,000 objects and uses an internal GPS receiver combined with SkyAlign technology to get you observing quickly, without needing to manually identify alignment stars.
That said, at 24kg this is not a grab-and-go setup. You will want a dedicated observing spot or a vehicle nearby, and collimation checks are part of owning any SCT at this aperture. The included 9x50 finderscope is a practical addition for centering targets before handing off to the GoTo system.
Imagers should note that the fork mount can be adapted for astrophotography with optional accessories, though serious imaging typically benefits from an equatorial wedge. Overall, this is a capable, well-supported instrument from a brand with a long track record.

Key Features
- 279mm aperture resolves fine planetary detail and reaches deep sky objects that 8-inch and smaller scopes cannot
- Internal GPS and SkyAlign alignment reduce setup time considerably, a genuine advantage for casual observing sessions
- GoTo database of 40,000 plus objects means you spend less time star-hopping and more time actually observing
- Dual fork arm mount is sturdy enough for visual use and can support astrophotography when paired with an optional equatorial wedge
- Schmidt-Cassegrain design folds a 2800mm focal length into a compact optical tube, making storage and transport more manageable for a scope this size
- Included Starry Night software is useful for session planning, particularly if you are newer to finding objects manually
- At 24kg total weight, this scope requires a committed setup routine, so factor in your observing site and transport situation before buying

I bought this telescope as a 50th birthday present to myself, and it did not disappoint. The optics are fantastic, the setup was a breeze, and it's a joy to operate. There is some minor assembly required, but the instructions are clear and it was only about 30 minutes from shipping box to first ligh...
I started off with a 130mm reflector, but quickly fell in love and decided I had to see more. I researched a LOT. I read reviews, I joined forums and asked opinions, I checked specs. This scope is comparable to the Meade LX200 series, but costs the same as the LX90 series. The general opinion of the...
The main optics and glass came full of black dirt which lowers the quality of the view, after expending 4,000 us you dont spect having this kind of problems in a brand new telescope. I will have to open it first day of unboxing due to this dirt
