Celestron CPC 800 GPS (XLT) Computerized Telescope

The internal 16-channel GPS automates the most tedious part of setup. It automatically inputs your precise location, date, and time into the NexStar+ hand control. This makes the initial SkyAlign procedure faster and more accurate, as you don't need to manually enter this information.

The system breaks down into two main components for transport. The optical tube and mount head assembly weigh 42 lbs, and the tripod weighs 19 lbs. While the 42 lb component is substantial, the ergonomic handles make it manageable for most adults to lift and place onto the tripod for setup.

With its 8" aperture and 843x light-gathering power, the CPC 800 excels on brighter deep-sky objects. On M42, you will resolve the Trapezium cluster at the core into four distinct stars and see extensive, detailed nebulosity. The f/10 focal ratio provides dark background skies, which enhances contrast on faint objects.

Out of the box, the CPC 800 comes with a 1.25" star diagonal and eyepiece. To use 2" eyepieces, you would need to purchase a separate 2" visual back that threads onto the rear cell of the telescope and a 2" star diagonal. This is a common and highly recommended upgrade for wide-field views.

The CPC 800 is a capable entry point for imaging planets and the Moon. For long-exposure deep-sky imaging, its Alt-Azimuth mount will cause field rotation. To overcome this, you will need to add an optional equatorial wedge (like the Celestron HD Pro Wedge) to convert the mount for equatorial tracking, which is necessary for sharp, long exposures.

XLT refers to Celestron's StarBright XLT optical coatings. This is a premium multi-layer coating system applied to the mirrors and corrector lens to maximize light transmission and produce brighter, higher-contrast images compared to standard coatings.
