Portability & serious performance come together in the Nex Star 6SE. Celestron's first new Schmidt-Cassegrain optical system in over a decade is now available in a high performance Altazimuth computerized telescope. The ultra-portable 6SE features a precision optical system with 1500mm focal length (f/10) & offers 44% more light gathering than a 5 Inch telescope. The Nex Star 6SE has all the same features as Celestron's most advanced computerized Go To telescopes, including our revolutionary Sky Align alignment technology, a sky tour feature, a database of over 40, 000 celestial objects & easy to use hand control. Plug the optional Sky Sync GPS Accessory into Nex Star's Auxiliary port & download data from orbiting GPS satellites for truly quick & easy alignments. The universe may be full of mysteries, but using the Nex Star 6SE isn't one of them!
