Designed to be an affordable entry level to mid-level computerized GoTo telescope, the Celestron NexStar 90SLT computerized telescope is loaded with valuable design features. With preassembled, adjustable stainless steel tripod and quick release fork arm and tube, NexStar 90SLT telescope can be set up in a matter of minutes – with no tools required! You can see details of the lunar surface, Venus and its phases, polar caps on Mars, Jupiter and its four moons, Saturn with its rings plainly visible and much more! It can also be used as a land-based spotting telescope.
Powered by 8 AA (user supplied) batteries or an optional AC adapter (#18778), these 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, view fascinating information about an object or simply know if a desired object is visible in the sky.
