Featuring high-quality Maksutov-Cassegrain optics, the NexStar 4SE is an ideal telescope for observing and photographing the wonders of space.

Featuring high-quality Maksutov-Cassegrain optics, the NexStar 4SE is an ideal telescope for observing and photographing the wonders of space. With a total weight of 21 lbs including the tripod, the ultra portable 4 SE features a precision optical system with 1,325 mm focal length (f/13) and is the first Maksutov system to ever feature our premium StarBright XLT coatings.

The 4 SE includes a camera control feature that allows you to remotely take a series of timed exposures using your digital SLR camera. Plus the Flip Mirror Control, Straight Through Photographic Port and Tripod featuring a built-in wedge help make short-exposure astrophotography a heavenly experience.

The NexStar 4 SE has all the same features as Celestron?s most advanced computerized GoTo telescopes, including our revolutionary SkyAlign alignment technology, a sky tour feature, a database of nearly 40,000 celestial objects and easy to use hand control.

Plug the optional CN-16 GPS Accessory into NexStar?s auxiliary port and download data from orbiting GPS satellites for truly quick and easy alignments. The universe may be full of mysteries, but using the NexStar 4 SE isn?t one of them.
