Celestron NexStar 5SE Computerised Telescope

Compact in scale yet notably capable, the Celestron NexStar 5SE is a Schmidt-Cassegrain telescope with a 125mm aperture, 1250mm focal length and f/10 focal ratio on a computerised alt-azimuth single fork arm mount. Celestron’s orange-tube SE design pairs established optics with an automated GoTo system, giving this model a strong balance of portability and guided observing.

The mount locates and tracks from a database of over 40,000 celestial objects, while SkyAlign supports quick setup through a simple three-object alignment process. A 25mm eyepiece is supplied for 50x magnification, and the telescope includes a StarPointer red dot finderscope, 1. 25-inch star diagonal and steel tripod with accessory tray. The optical tube is aluminium and fitted with StarBright XLT optical coatings. For users building a more advanced setup, the NexStar 5SE also supports a range of compatible accessories including SkySync, StarSense AutoAlign and imaging options.
