Celestron NexStar Evolution 6 Computerised Telescope

Built for streamlined, app-based observing, the Celestron NexStar Evolution 6 is a computerised Schmidt-Cassegrain telescope with a 150mm aperture, 1500mm focal length and f/10 optical system on a computerised alt-azimuth single fork arm mount. Built-in Wi-Fi works with the free Celestron SkyPortal app, giving smartphone or tablet control alongside real-time sky navigation and SkyAlign alignment.

This 6-inch model pairs StarBright XLT optical coatings with a rechargeable lithium iron phosphate battery, integrated carry handles and manual clutches in both altitude and azimuth. The all-metal tripod includes a metal accessory tray, while two accessory trays provide storage for up to 7 eyepieces, with adjustable red LED illumination on one tray. A USB charging port is built in for powering a smart device during observing sessions, and the telescope is also compatible with the HD Pro Wedge when used with the CPC tripod, both available separately.
