Manufacturer Description

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 pounds including the tripod, the ultra portable 4SE features a precision optical system with 1,325mm focal length (f13) and is the first Maksutov system to ever feature our premium StarBright XLT coatings.



The 4SE 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.

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 4SE isn't one of them.



In the tradition of Celestron's famous orange optical tubes, the NexStar SE Family combines the classic heritage of the original orange tube telescopes with state-of-the-art features including a fully computerized operating system, flash upgradeable hand control, our superior StarBright XLT coatings, our revolutionary SkyAlign telescope alignment software, and much more.



Whether you are a seasoned astronomer looking for a portable scope with advanced features, or just starting your astronomy adventure and looking for an easy way to enjoy the night sky, a NexStar SE will help you take a closer look. Every NexStar SE includes a version of The Sky software Level 1 Planetarium software for exploring the Universe on your PC and printing out custom star charts of the sky. In addition, you receive our NexRemote software that allows you to operate your telescope via your PC. This software package, valued at over $100, is included free with your NexStar SE!
