Celestron NexStar 4SE Telescope

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 Technology

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?

Advanced Features Let the Celestron NexStar 4SE Telescope Grow with You

The NexStar 4SE is compatible with all the high-tech accessories. Provide GPS coordinates to your telescope with SkySync. If you want to explore the world of astroimaging, the 4SE is a perfect choice. Its built-in wedge allows you to track long exposures. Or, if you’re interested in imaging the Moon and planets, pair your NexStar 4SE with one of our ZWO planetary imaging cameras.

Please note that for DSLR photography, you will require both a Celestron MAK T-Adapter (not the SCT T-Adapter), and a DSLR T-Ring for your specific camera.
