With a generous 4 inch aperture the Celestron NexStar 4SE Telescope provides excellent light-gathering ability at an affordable price. You’ll be thrilled with views of the Moon and planets, along with deep sky objects like the Orion Nebula while retaining a compact size. Its fully automated GoTo computerised mount with database of 40,000+ celestial objects automatically locates and tracks objects for you.
SkyAlign makes aligning a computerized telescope fast, easy, and accurate. Simply point at any three bright objects in the sky and the telescope aligns itself. From there, navigation and tracking is as easy as pushing a button.
Unique Single Fork Mount Design
Debate about the “best” telescope is nearly as endless as the Universe itself but we know one thing quite well – the best telescope is the one you will use most often! That’s why Celestron’s engineers created NexStar SE’s unique, single fork arm mount. It’s perfectly portable and makes for quick and easy set up compared to many designs. The NexStar SE disassembles into several compact pieces so it’s easy to transport. You’ll have no problem getting the NexStar SE to your favorite observing site, or setting it up quickly at home.
Of course, it’s what’s inside the mount that really counts. Sturdy construction from high-quality components give the Celestron NexStar 4SE Telescope the pointing and tracking accuracy needed to observe and follow your favorite targets with push-button ease. How many other telescopes can locate and track over 40,000 celestial objects – or take a Sky Tour and let your telescope show you the best objects currently visible?
