Product Description

CELESTRON - NexStar 4SE 102mm Maksutov-Cassegrain Computerized Telescope - 11049

The NexStar 4 SE has all the same features as Celestron's most advanced computerized GoTo telescopes, including their revolutionary SkyAlign' alignment technology, a sky tour feature, a database of nearly 40,000 celestial objects and easy to use hand control. Celestron also makes it simple to insert the optional SkySync GPS Accessory (93969) into NexStar's auxiliary port and download data from orbiting GPS satellites for truly quick and easy alignments. The universe may be full of mysteries, but using the NexStar 4 SE isn't one of them. In the tradition of Celestron's famous orange optical tubes, the new NexStar SE Family combines the classic heritage of the original orange tube telescopes with state-of-the-art features including a fully computerized operating system, flash upgradeable hand control, optically superior StarBright XLT coatings, and Celestron's revolutionary SkyAlign telescope alignment software. Whether you are a seasoned astronomer looking for a portable scope with advanced features, or just starting to enjoy astronomy and are looking for an easy way to enjoy the night sky, a Celestron NexStar 4SE Maksutov-Cassegrain telescope will help you take a closer look. In addition, you receive NexRemote software that allows you to operate your telescope via your PC.

The NexStar 4 SE Telescope provides exquisite views of the wonders of the Universe. This 4” Maksutov-Cassegrain Telescope is equipped with Celestron's patented Sky – Level 1 Planetarium software. Supporting the classy metallic orange tube is a sturdy adjustable metal tripod with a motorized altazimuth wedge mount and the NexStar computer controller. One of the awesome features of this Computerized Telescope is its pre-programmed GoTo tracking system. The telescope can locate and track nearly 40,000 pre-set celestial objects with just one push of a button. It actually makes astro-imaging a breeze. This state of the art telescope is ideal for observing or imaging the many wonders of space. NexStar 4 SE is also very portable with its total weight of just 21 pounds including the tripod. The Celestron NexStar 4 SE Maksutov-Casesgrain telescope is pre-loaded with a large astronomical database of over 40,000 pre-programmed celestial objects, 200 user-defined targets, and useful information on over an additional 200 objects. Since this telescope is of Maksutov-Cassegrain design with a very slow focal ratio, planets and the moon will look outstanding. It also features the Celestron patented SkyAlign technology which allows you to focus on any three bright stars, making search and tracking much easier. To aid you in accurately locating and focusing manually on objects, you can use the StarPointer finderscope. This added feature makes manual tracking possible for users of all skill levels.



  • Fully automated GoTo mount with database of 40,000+ celestial objects automatically locates and tracks objects for you.
  • Unique single fork arm design and sturdy steel tripod all break down into separate components for easy transport and quick assembly.
  • 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.
  • 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.
