"Celestron StarSense AutoAlign the revolutionary technology in the award-winning SkyProdigy telescope is now available for almost every Celestron computerized telescope. Before StarSense, using a computerized telescope required a lengthy alignment process of finding and centering at least two bright stars in the telescope's eyepiece. But StarSense automatically aligns itself, no user input needed. With StarSense, you become an instant astronomer even if you've never used a telescope before. StarSense is not only compatible with all of Celestron's current computerized telescope models, but backwards compatible with many older models as well. (See compatibility list below.) The StarSense AutoALign includes a small digital camera that attaches to the telescope's optical tube, along with a specialized hand controller. Just set up the accessory, push the Align button on the hand controller, and StarSense starts capturing and comparing images of the night sky against its internal database of 40,000 celestial objects. In about three minutes, StarSense will gather enough information to triangulate its position and align itself. Then, press the Sky Tour button: StarSense will automatically slew to all the best stars, planets, galaxies, and more based on your exact time and location. Even the most advanced telescope users will love using the affordable StarSense Accessory.
