Celestron 180mm f/15 CGX 700 Maksutov-Cassegrain Telescope with Computerized Equatorial Mount, Tripod and StarBright XLT Coatings

Optical Design: The Mak is a catadioptric telescope, which means the optical design includes both a lens and a mirror. The light coming through a Mak passes through the corrector lens to the primary mirror and back to a spherical secondary mirror before it hits your eyepiece. Images are bright, sharp, and virtually free of chromatic aberration. CGX Mount & Tripod: The CGX, with its 55 lb load capacity, is Celestron’s most innovative, state-of-the art, computerized equatorial mount to date, and provides a very sturdy and rigid platform. CGX Motor Drive System: The drive system utilizes low cog DC Servo motors with integrated optical encoders, belt and pulley motor connection, spring-loaded steel worm gears supported by precision sealed bearings, and brass worm wheels for smooth, accurate slewing and tracking performance with little backlash. Ready for Remote Imaging: For remote imaging, the mount needs a way to be controlled by an external computer. The CGX has two ways to connect to a computer via USB 2.0. First, it has a USB port on the mount itself which is used exclusively to connect to a PC running the included Celestron PWI telescope control software. StarBright XLT Technology: StarBright XLT is Celestron’s revolutionary optical coating system that outperforms any other coating in the commercial telescope market and ensure maximum light transmission.
