Description

The Celestron NexStar 4SE Computerized Cassegrain - 102 mm is the perfect choice for your first serious telescope, offering striking views at an economical price. The 4SEs four-inch primary mirror packs enough light-gathering ability to observe the best that the solar system has to offer: Saturns rings, the cloud bands on Jupiter, and geographic features on the surface of the Moon. When it comes to deep sky objects, take your 4SE to a dark-sky site and youll see hundreds of pinpoint stars in the Hercules Globular Cluster, the spiral arms of the Whirlpool Galaxy, and more.

Celestrons engineers created NexStar SEs unique, patented single fork arm mount. Its perfectly portable and makes setup quick and easy. Whats more, the NexStar SE breaks down into several lightweight and compact pieces, making it easy to transport, even in small vehicles. Youll have no problem getting the NexStar SE to your favorite observing site, or setting it up quickly in your backyard.

Of course, its whats inside the mount that really counts. Sturdy construction from high-quality components give NexStar SE the pointing and tracking accuracy needed to observe and follow your favorite targets with push-button ease. Use the included NexStar+ hand control to locate over 40,000 celestial objects, or take a Sky Tour and let your telescope show you the best objects currently visible.

Aligning your telescope is simple and painless, too, thanks to SkyAlign. This process makes alignment as easy as 1-2-3: just center three bright objects in your eyepiece and press ALIGN. For even easier alignment, attach our StarSense AutoAlign and your NexStar SE aligns itself!
