CELESTRON CPC 800 XLT GPS SCT

The Celestron CPC 800 XLT GPS is a Schmidt-Cassegrain telescope with diffraction-limited optics for high resolution observation. With a fully computerized dual fork arm Alt-Azimuth mount, the CPC 800 is the perfect instrument for visual astronomy and outreach. 

Celestron's StarBright XLT optical coatings on each surface give maximum light transmission across the visual spectrum between 400 - 750nm. Unlike standard aluminium mirror coatings which only reflect about 86-88% of light, StarBright XLT coated-mirrors reflect a staggering 95%. The entire system including corrector lens and magnesium fluoride/hafnium dioxide AR coatings give a total transmission of 83.5% averaged over the entire visual spectrum, a 16% improvement over the previous StarBright coatings. 

The CPC mount uses Celestron's proven NexStar computer control technology with an target database of over 40,000 objects. The re-designed drive base and mechanics offer quiet slewing, larger drive gears and quick release clutch for reliable and easy operation. Star alignment is fast thanks to the 3-star SkyAlign process and the included 9 x 50 finderscope makes centering objects pain-free.

These mounts are heavy duty and stand up to frequent use even in harsh environments. We successfully employed them for nightly star parties in Uluru for many years without any problems.

The mount features an auxiliary port for autoguider and GPS accessory (sold separately). Mount and motor controller firmware can be upgraded via the handset over the internet. An RS-232 cable is included for advanced control over the telescope using a computer. The CPC mount has Permanent PEC (periodic error correction) ensuring stable tracking. The included tripod's 2" stainless steel legs provide a rock solid platform.
