Celestron Nexstar 4SE Computerised Telescope

• Celestron’s iconic “orange tube” design is updated with all the latest features to provide the best stargazing experience for beginners and experienced observers alike.
• 4-inch aperture provides excellent light-gathering ability at an affordable price. You’ll get impressive views of the Moon and planets, along with deep sky objects like the Orion Nebula, while retaining a compact form factor.
• Fully automated GoTo mount with database of 40,000+ celestial objects automatically locates and tracks objects for you.
• SkyAlign technology gets your telescope aligned and ready to observe in minutes. Even if you’re unfamiliar with the night sky, you can easily align your telescope on any three bright objects.
• Unique single fork arm design and sturdy steel tripod all break down into separate components for easy transport and quick assembly.

The Celestron Nexstar 4SE’s four-inch primary mirror packs enough light-gathering ability to observe the best that the solar system has to offer: Saturn’s rings, the cloud bands on Jupiter, and geographic features on the surface of the Moon. When it comes to deep sky objects, take your Celestron Nexstar 4SE to a dark-sky site and you’ll see hundreds of pinpoint stars in the Hercules Globular Cluster, the spiral arms of the Whirlpool Galaxy, and more.

Revolutionary Single Fork Arm Mount

We know the best telescope is the one you will use most often. That’s why Celestron’s engineers created NexStar SE’s unique, patented single fork arm mount. It’s perfectly portable and makes setup quick and easy. What’s more, the NexStar SE breaks down into several lightweight and compact pieces, making it easy to transport, even in small vehicles. You’ll have no problem getting the NexStar SE to your favorite observing site, or setting it up quickly in your backyard.

Of course, it’s what’s inside the mount that really counts. Sturdy construction from high-quality components give Celestron Nexstar 4SE 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!

Advanced Features Let the NexStar SE Grow with You

The NexStar SE is compatible with all the high-tech accessories advanced users love. Provide GPS coordinates to your telescope with SkySync, or add automatic alignment functionality with StarSense AutoAlign.

Its built-in wedge allows you to track long exposures. if you’re interested in imaging the Moon and planets, pair your Celestron Nexstar 4SE with one of our Skyris cameras. From your first observing session and for years to come, the NexStar SE is your trusted companion.
