    Celestron NexStar 90 SLT Computerized Telescope

    Designed to be an affordable entry level to mid-level computerized GoTo telescope, the Celestron NexStar Star Locating Telescope (SLT) refractors and reflectors are available in the most popular sizes and are loaded with valuable design features. With pre-assembled, adjustable stainless steel tripods, and quick release fork arms and tubes, NexStar SLT telescopes can be set up in a matter of minutes. No tools required! You can see details of the lunar surface, Venus and its phases, Mars resolved as an orange disc, Jupiter and its four Galilean moons, Saturn with its rings plainly visible, and much more! Most NexStar SLTs can also be used as a land-based spotting telescope.

    Powered by 8 AA user supplied batteries or an optional AC adapter (#CE-18773), these Celestron NexStar GoTos love to travel. The internal battery compartment provides power to the high precision servo motors for rigid low-vibration performance while eliminating cord wrap issues associated with external battery packs. With the NexStar's ergonomically-designed hand control, the user is free to remove the hand control from its holder for remote use or leave it cradled for hands-free operation. With a touch of a button, you can select the object catalog, change the slew speed (there are nine speeds), view fascinating information about an object, or simply know if the desired object is visible in the sky.

    At the heart of the Celestron Next Star 90 SLT, is a quality 90mm Maksutov-Cassegrain telescope with an aperture of 90 mm (3.54 in). With a long focal ratio of f/13.89 and focal length of 1250 mm (49.21 in), this telescope also features multi-coated high-quality Celestron optics and makes use of a rack and pinion style focuser. The whole system (including the drive and computer units) is easy to transport and easy to use!

    Celestron's most affordable NexStar telescope turns starry nights into space odysseys. They come with a fully computerized hand control with a database of over 4,000 celestial objects. With its pre-assembled, adjustable steel tripod, the Celestron NexStar 90 SLT can be up and ready to use in a matter of minutes. Aligning is a breeze with the new SkyAlign alignment technology and the included StarPointer Finderscope with a red LED. With the NexStar 90 SLT, you can see breathtaking views of the lunar landscape, and most of our solar-system's planets at medium and high magnifications. To use the SkyAlign technology, simply input the date, time, your location (the CPC models have built-in GPS that does this for you), and then align the telescope to three bright stars of your choosing. You do not need to know the names of the stars, you could even pick the moon or bright planets! The NexStar Computer system will automatically figure out which stars were chosen and then align the telescope. There is no need to point the telescope North or to level the optical tube; the initial position of the telescope is irrelevant. This makes for a fast and very easy method for aligning the telescope.
