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.You may also like Celestron AstroMaster 102AZ Telescope, 4in, f/6.5, 241x, 8.75in Tube.
