About Celestron NexStar SE Open Box

What sets the NexStar 4 SE Maksutov-Cassegrain Computerized Telescope apart is its unique blend of advanced features and superior optics, all housed in Celestron's signature orange-tube design. This user-friendly system is an ideal choice for both novice and experienced astronomers, offering breathtaking views of the cosmos at an affordable price.

This telescope is a modern interpretation of our founder, Tom Johnson's vision from the 1970s. Johnson revolutionized the world of astronomy with Celestron's Schmidt-Cassegrain telescopes, making high-quality optical instruments accessible to all. Today, we continue to honor his legacy by enhancing this design with innovative features, while maintaining our commitment to quality and affordability.

The NexStar 4SE's four-inch primary mirror boasts impressive light-gathering capabilities, allowing you to explore the best of our solar system. Witness the intricate rings of Saturn, the dynamic cloud bands on Jupiter, and the detailed geographic features on the Moon's surface. For deep sky objects, transport your 4SE to a dark-sky site and marvel at the hundreds of stars in the Hercules Globular Cluster, the spiral arms of the Whirlpool Galaxy, and beyond.

Our revolutionary single fork arm mount, a patented design unique to the NexStar SE series, ensures portability and quick setup. The telescope disassembles into compact, lightweight pieces, making it easy to transport even in small vehicles. This design, coupled with sturdy construction from high-quality components, provides the pointing and tracking accuracy needed to observe and follow celestial objects with ease.

The NexStar 4SE comes with a NeXStar+ hand control, allowing you to locate over 40,000 celestial objects. The SkyAlign feature simplifies the alignment process, requiring you to just center three bright objects in your eyepiece and press ALIGN. For even more convenience, attach our StarSense AutoAlign for automatic telescope alignment.

The NexStar SE is designed to grow with you, compatible with high-tech accessories like SkySync for GPS coordinates and StarSense AutoAlign for automatic alignment. For astroimaging enthusiasts, the 4SE's built-in wedge enables long exposure tracking. The telescope's secondary mirror can be replaced with a DSLR or astronomical CCD camera for wide field images captured at f/2 using a Fastar/HyperStar lens assembly. For imaging the Moon and planets, pair your NexStar 4SE with one of our Skyris cameras.

From your first observing session and for years to come, the NexStar 4 SE Maksutov-Cassegrain Computerized Telescope is your reliable partner in exploring the wonders of the universe.
