Intelligent Design
Can be powered by 8 AA (user supplied) batteries or a suitable AC adapter or portable power-tank. This telescope loves to travel! The ergonomically designed hand control can be removed from its holder for remote use or left in situ 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.

Celestron’s Revolutionary SkyAlign
Using Celestron’s 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 select the Moon or bright planets!
