Featuring Maksutov-Cassegrain optics, the Celestron NexStar 4 SE is an ideal telescope for observing and photographing celestial or terrestrial subjects. With a weight of just 21 lb (9.5 kg) including the tripod, the ultra-portable 4 SE features a precision optical system with 1,325 mm focal length at ƒ13, and is the first Maksutov system from Celestron to feature StarBright XLT multi coatings.
StarBright XLT high transmission coatingsSkyAlign allows alignment on any three bright celestial objects, making for a rapid, efficient alignment process. It then functions as a 'go-to' system accepting commands through the handset and pointing the optical assembly toward any one of nearly 40,000 objects stored in its database. Using the (optional) CN-16 GPS accessory connection and an external GPS (not included), alignment is entirelyautomatic.NexRemote telescope control software and RS-232 cable included for advanced control of the telescope with a PCStarPointer finderscope helps with alignment and locating objectsFlash-upgradeable hand control software and motor control units by way of downloadable updatesRobust, computerized altazimuth mountStar Diagonal internal flip mirror for straight or 90-degree viewing angle.
