Overview
The Celestron CPC 1100 GPS (XLT) pairs an 11" diffraction-limited Schmidt-Cassegrain optical tube with a fully computerised dual fork arm altazimuth mount and internal 16-channel GPS. The 2800mm focal length at f/10 and StarBright XLT coatings gather 1593x more light than the human eye, resolving faint deep-sky objects and planetary detail with 0.5 arcsecond Rayleigh resolution. The GPS downloads date, time, and location automatically, then SkyAlign aligns on any three bright objects. The NexStar+ hand control locates and tracks from a 40,000+ object database, and the heavy-duty tripod with 2" stainless steel legs provides a stable platform for the 29.5kg optical tube and mount.
Key Features
- 11" Diffraction-Limited SCT – The 279.4mm aperture with StarBright XLT coatings gathers 1593x more light than the human eye, resolving faint deep-sky objects and planetary detail with 0.5 arcsecond Rayleigh resolution and a limiting stellar magnitude of 14.7.
- Dual Fork Arm GoTo Mount – A fully computerised altitude-azimuth dual fork arm mount with DC servo motors and 9 slew speeds (max 5°/sec) provides stable tracking and pointing, with a redesigned drive base and quick-release clutch.
- Internal GPS and SkyAlign – The 16-channel GPS downloads date, time, and location automatically, then SkyAlign aligns on any three bright objects without needing to know their names.
- 40,000+ Object Database – The NexStar+ hand control locates and tracks from a database of over 40,000 objects, with 100 user-definable and enhanced information on more than 200.
- Permanent PEC and Autoguide Port – Permanent programmable PEC counteracts tracking errors during long-exposure imaging, and the autoguide port supports guided astrophotography.
- Heavy-Duty Stainless Steel Tripod – The tripod features 50.8mm (2") stainless steel legs and an accessory tray, with a design that lets you attach the telescope in the dark.
- Ergonomic Design and Hand Control Holder – Carrying handles make the 29.5kg mount and tube easier to lift, and the hand control holder keeps the NexStar+ controller accessible hands-free.
- 2-Year Celestron Warranty – Backed by Celestron's 2-year warranty for confidence in the field.
Ideal For
- Visual observers wanting the largest aperture in the CPC GPS range
- Astrophotographers planning guided imaging with the autoguide port
- Users wanting GPS-assisted alignment and a 40,000+ object database
- Observers wanting a rock-solid dual fork arm mount with minimal vibration
- Those with a permanent or semi-permanent observing location
