Celestron NexStar 8SE Computerised Telescope

For observers ready to move into a more capable computerised setup, the Celestron NexStar 8SE brings together an 203. 2mm Schmidt-Cassegrain optical tube, 2032mm focal length and f/10 focal ratio on a computerised alt-azimuth single fork arm mount. As the largest model in the SE range, it pairs substantial aperture with a format that breaks down into separate components for transport and straightforward assembly.

Celestron’s orange-tube NexStar 8SE combines automated object location and tracking with a database of 40,000 celestial objects, operated through the included NexStar+ hand control. SkyAlign support keeps setup simple, while StarBright XLT optical coatings and the supplied 25mm eyepiece complete a well-specified system for lunar, planetary and deep-sky observation. The steel tripod includes an accessory tray, and the mount supports multiple tracking rates and alignment procedures for flexible observing sessions.
