Overview
The Celestron CPC 800 GPS (XLT) pairs an 8" Schmidt-Cassegrain optical tube with a dual fork arm computerised mount and internal GPS. The 2032mm focal length at f/10 and StarBright XLT coatings deliver sharp, bright views of the Moon, planets, and deep-sky objects, with 843x light gathering compared to the human eye. The internal 16-channel GPS downloads date, time, and location automatically, then SkyAlign aligns the telescope 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.
Key Features
- 8" Schmidt-Cassegrain Optics – The 203.2mm aperture with StarBright XLT coatings gathers 843x more light than the human eye, resolving planetary detail and deep-sky objects with 0.69 arcsecond Rayleigh resolution.
- Dual Fork Arm GoTo Mount – A 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 enhanced information on more than 200 and 100 user-defined slots.
- Periodic Error Correction – Permanent programmable PEC counteracts minor tracking errors during long-exposure imaging, keeping objects centred over extended sessions.
- Heavy-Duty Stainless Steel Tripod – The tripod features 50.8mm (2") stainless steel legs and an accessory tray, providing a rigid platform for the 19.1 kg mount and optical tube.
- Autoguide and USB Ports – An autoguide port supports guided astrophotography, and the hand control's USB 2.0 port allows PC connection and firmware updates.
- 2-Year Celestron Warranty – Backed by Celestron's 2-year warranty for confidence in the field.
Ideal For
- Visual observers wanting a stable, large-aperture GoTo telescope
- Astrophotographers planning guided imaging with an optional wedge
- Users wanting GPS-assisted alignment and a 40,000+ object database
- Observers wanting a rock-solid dual fork arm mount with minimal vibration
