Celestron NexStar 6SLT Computerised Telescope

For compact Schmidt-Cassegrain performance with guided object finding, the Celestron NexStar 6SLT brings together a 150mm aperture, 1500mm focal length and f/10 optical system on a computerised alt-azimuth single fork arm mount. Within the first moments of setup, its pre-assembled adjustable stainless-steel tripod, no-tool assembly and NexStar+ hand control make the telescope straightforward to prepare for an evening under the stars.

This Celestron model pairs the 6-inch optical tube with StarBright XLT optical coatings and SkyAlign technology, allowing alignment using three bright objects in the sky. The NexStar+ hand control provides access to a database of 40,000 celestial objects, while the supplied 20mm and 9mm eyepieces offer 75x and 167x magnification. A StarPointer red dot finderscope, 1. 25-inch star diagonal and accessory tray are included, making it a well-equipped choice for beginners and for general night-sky observing.
