The Mount & Technologies


Computerized AltAzimuth Mount  The NexStar SLT telescope features a single fork arm altazimuth mount, which allows the telescope to track the desired objects as they appear to move across the night sky. The mount sits on a pre-assembled, adjustable steel tripod.

NexStar+ Hand Control  This computerized hand control enables you to automatically slew to any of 40,000 celestial objects with the push of a button. The NexStar+ database includes more than 600 galaxies, 300 clusters and dozens of beautiful binary stars. Not sure what to observe? Choose the Sky Tour feature and the NexStar+ hand control will automatically generate a list of all the best celestial objects currently visible based on your exact time and location.

SkyAlign Technology  Our proprietary SkyAlign alignment procedure makes setting up and using a computerized telescope faster and easier than ever before. Point the telescope at three bright objects in the sky, and the telescope can triangulate its position and locate any other object in the sky automatically. You dont need to know the names of the starsyou can even pick the Moon or bright planets! For more information about our SkyAlign technology, visit here.

Power  Go anywhere! Feel free to enjoy your NexStar SLT in remote dark sky locationsits powered by 8 AA batteries (not included) or a PowerTank portable battery (sold separately). 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. You may also power your telescope with a 12V AC adapter (sold separately).

Accessories Included

Your telescope includes a StarPointer red dot finderscope, a star diagonal, and two eyepieces (25mm and 9mm). The two eyepieces offer different magnifications for low- or high-powered observing. The star diagonal provides a right-side-up view and a more comfortable viewing angle when looking up at the sky. The StarPointer red dot finderscope will help you quickly center an object in your eyepiece for easier observing.
