The Astro Fi 5" Schmidt-Cassegrain is a fully featured telescope that can be controlled with your smartphone or tablet using the free Celestron SkyPortal app. Celestron’s SkyPortal 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 Astro Fi telescope automatically slews to the object, while the screen displays information about it.
The Astro Fi 5" Schmidt-Cassegrain creates its own wireless connection, so it can communicate with your device even in remote locations where Wi-Fi or cellular networks aren’t available. Getting ready to observe is quick and painless thanks to Celestron’s award-winning SkyAlign 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.
