The Celestron NexStar 90SLT is a computerized telescope that offers a database of more than 40,000 stars, galaxies, nebulae, and more. The telescope locates your object with pinpoint accuracy and tracks it. At the heart of the telescope’s Maksutov-Cassegrain optical design, a 90mm primary mirror gives fully color-corrected views ideal for astronomical use. The 90SLT comes with a fully computerized NexStar+ hand control. The computerized hand control gives you the ability to automatically slew to any of its 40,000+ objects, including over 600 galaxies, 300 clusters, and dozens of beautiful binary stars. This telescope for adults and kids to be used together is ideal for weekend camping trips or excursions to dark sky sites. Its compact form factor makes it easy to transport and assemble just about anywhere. With its pre-assembled, adjustable steel tripod, the NexStar 90SLT can be up and ready to use in a matter of minutes. Our SkyAlign alignment technology and the included StarPointer Finderscope with a red LED make aligning a breeze. Simply center any three bright objects in the eyepiece and the NexStar SLT aligns to the night sky, ready to locate thousands of objects. The NexStar 90SLT Computerized GoTo Telescope also includes a free download of our Starry Night Special Edition astronomy software for an interactive sky simulation.
