At a dark sky location, you'll see hundreds of pinpoint stars in the Hercules Globular Cluster, galaxies, and more. Celestron’s XLT optical coatings aid in light transmission so you get brighter views.

Center any three objects in the eyepiece and your telescope can calculate its exact location and generate a list of objects currently visible. Choose from a database of 40,000 objects or let your telescope take you on a Sky Tour of tonight’s best objects.

      Reminiscent of Celestron’s classic orange tube telescopes from the 1970s, but with all the latest technological advances, the NexStar SE is designed to grow with you. It’s compatible with all of Celestron’s latest telescope accessories: StarSense AutoAlign, which aligns your telescope automatically in less than three minutes, the SkyQ Link 2 WiFi Module for navigating the sky with your smartphone or tablet, and more.

      How Celestron Schmidt-Cassegrain Telescopes Work

      Since their design was perfected by Celestron founder Tom Johnson in the 1960s, the Schmidt-Cassegrain telescope has been a superior all-around performer for both terrestrial and astronomical viewing as well as astroimaging. Celestron’s versatile, cost-effective design has reigned as a top choice for most amateur astronomers.

      Schmidt-Cassegrain telescopes and other “catadioptrics” use mirrors and specialized lenses to shorten the light path, giving them a much more compact design than other telescopes of a similar focal length.

      First, the light passes through the Schmidt corrector lens on the outermost edge of the telescope. Although it appears flat to the naked eye, the Schmidt corrector is actually aspherical; its glass is figured for hours to achieve the desired shape. After passing through the corrector, the light strikes the primary mirror and reflects up to the secondary mirror. From there, it bounces back down and travels through to an eyepiece or imaging sensor at the back of the telescope.

      Schmidt-Cassegrain Advantages

      • Best all-purpose telescope design; works for terrestrial observing, astronomical observing, planetary imaging, and deep sky imaging.
      • Bright, razor sharp views.
      • Extremely compact and portable.
      • Easy to use, durable and virtually maintenance-free.
      • Much less expensive than refractors of equal aperture.
      • Compatible with a wide variety of telescope accessories.

      Schmidt-Cassegrain Disadvantages

      • More expensive than Newtonians of equal aperture.
      • Slight light loss due to secondary mirror obstruction compared to refractors.
