Unbeatable performance from an advanced computerised telescope in an ultra-portable size.
It's often said that "the best telescope is the telescope you use the most", and we can guarantee that this will be that telescope. It's truly a 'grab and go' instrument that offers unbelievably good views of the Moon, planets, stars and even deep sky objects, all delivered at the touch of a button, and at a very keen price.
Celestron's signature orange-tube telescope combines advanced features and excellent optics in one easy-to-use system, the NexStar 4SE. Its the perfect choice for your first serious telescope, offering striking views at an economical price.
In the 1970s, Celestrons Schmidt-Cassegrain telescopes brought the hobby of astronomy to the masses and established Celestron as the worlds premier telescope maker. Our founder, Tom Johnson, invented Celestrons proprietary method of producing Schmidt corrector plates for superior views and maximum portability. Johnson believed in creating high-quality optical instruments at an affordable price, and inspired a generation of amateur astronomers.
Four decades later, weve improved upon this design by adding cutting-edge features, while staying true to our founders intent.
View the Universes Most Impressive Celestial Objects
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.
Revolutionary Single Fork Arm Mount
We know the best telescope is the one you will use most often. Thats why 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!
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. With Celestron's SkyPortal accessory, you can even add a connection to your smartphone and Celestron's impressive SkyPortal navigation app.
Its built-in wedge allows you to track long exposures. if youre interested in imaging the Moon and planets, pair your NexStar 4SE with one of our cameras. From your first observing session and for years to come, the NexStar SE is your trusted companion.
