Celestron 's NexStar 8 SE 203mm f/10 Schmidt-Cassegrain GoTo Telescope is a powerful, versatile and user-friendly Schmidt-Cassegrain style telescope that can be used for observing everything from the Moon and planets to deep sky objects like galaxies and nebulae. Using Celestron's improved proprietary StarBright XLT multi-coating system, light transmission is increased throughout the entire optical path with anti-reflection multi-coated lenses, highly reflective multi-coated mirrors, and 4-element rare-earth glass. While the focal ratio is a slow f/10, the scope's precision tracking system allows it to be a competent astrophotography/astroimaging platform for the Moon and planets.
Driving the dual servo motors on the mount is the brains of the NexStar 8: the iconic NexStar computer hand controller. Packed with over 40,000 celestial objects, it can hold up to 200 additional user-defined destinations and is updateable via the Celestron website. It has multiple alignment procedures to get you observing fast - including the super-easy SkyAlign system. Capable of being used in the northern or southern hemispheres, the NexStar has sidereal, lunar and solar tracking speeds to accurately follow near and deep-sky objects, plus nine slew speeds.
