The Celestron NexStar 8SE is a computerized Schmidt-Cassegrain telescope with an 8-inch (203.2mm) aperture. It keeps the classic orange tube design and is meant for both beginners and experienced observers. The aperture gathers enough light for views of the Moon and planets, and of deep sky objects such as the Whirlpool Galaxy and the Hercules Globular Cluster.
The telescope sits on a computerized altitude-azimuth single fork arm mount with DC servo motors. The NexStar+ hand control locates and tracks objects from a database of more than 40,000. It also offers a Sky Tour of the best objects currently visible. SkyAlign aligns the telescope when you center three bright objects in the eyepiece and press ALIGN. The mount and the steel tripod break down into separate components for transport and assembly.
The NexStar 8SE works with StarSense AutoAlign for self-alignment. SkyQ Link lets you control it from an iPhone or iPad, and SkySync adds GPS functionality. It is Fastar-compatible for wide field imaging and can be paired with NexImage cameras for planetary imaging.
