Product information

Excellent high quality computerized GoTo Maksutov telescope, the NexStar 90 SLT is supplied with valuable design features. With preassembled, adjustable stainless steel tripods, and quick release fork arms and tubes, NexStar SLT telescopes 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, Jupiters cloud belts and its four moons, Saturn with its rings plainly visible including the Cassinni division when the rings are open and much more! Supplied with two quality eyepieces allowing general viewing along with a high 139x magnification for serious Planetary observation.

Intelligent Design
Powered by 8 AA (user supplied) batteries or an optional mains adaptor 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 NexStars 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.

Celestrons Revolutionary SkyAlign
Using Celestrons patented SkyAlign (patent pending), simply input the date, time and location into the hand control then slew the telescope to any three bright celestial objects in the sky. You do not need to know the names of the stars, you can even pick the Moon or bright planets!
