Product Description

Celestron NexStar 90 SLT Computerized Mak Cassegrain Telescope

 

Created to be an excellent entry-level telescope into the exciting frontier of astronomy, the Celestron NexStar 90 SLT Computerized Refractor Telescopecomes pre-built with many exciting features. With pre-assembled, adjustable stainless steel tripods, and quick-release fork arms and tubes, this NexStar SLT telescope can be set up in a matter of minutes - no dramas at all! Cleverly Created Powered by 8 AA user-supplied batteries, an optional AC adapter, optional car-battery adapter, or powertank power source, the NexStar GOTO would suit any nomad. The internal battery compartment provides power to the high-precision servo motors for rigid low-vibration performance - while simultaneously eliminating annoying cord wrap issues associated with external battery packs. The NexStar's comes with an ergonomically engineered hand controller, allowing the user to remove the hand control from its holder for remote use or leave it cradled for hands-free operation. At the touch of a button, you can select an object from the object catalog, change the slew speed, view fascinating information about an object, or simply find out whether your desired object is visible in your skies. The SkyAlign Revolution by Celestrong Using Celestron's patented SkyAlign, simply input the date, time, and location into the hand control then slew the telescope to any three bright celestial objects in the sky. Voila and that's it - alignment so easy it's hard to believe! You'll finally be able to spend your evening observing the night sky instead of aligning your telescope! Celestron NexStar 90 SLT Computerized Maksutov
