Our new Cosmos Celestron Navigator mobile app replaces the traditional telescope hand control for a 100% wireless experience. Just hold your smart device up to the night sky. When you find an object you d like to view, tap the screen. Your Cosmos 90GT automatically slews to the object, while the screen displays information about it. It s never been more fun to explore the universe. The first WiFi telescope commercially available, the Cosmos 90GT creates its own wireless connection, so it can communicate with your device even in remote locations where WiFi or cellular networks aren t available. Getting ready to observe is quick and painless thanks to Celestron s award-winning Sky Align technology. Center any three bright objects in the eyepiece, and your telescope calculates its position. You can even generate a Sky Tour of all the best celestial objects to view based on your exact time and location.
