With the Celestron Astro Fi 90mm Refractor Telescope you can control your telescope via integrated WiFi using the free Celestron SkyPortal app for iPhone, iPad, and Android devices.

The Astro Fi 90mm Refractor is a fully featured telescope that can be controlled with your smart phone or tablet using the free Celestron SkyPortal app. Celestronís 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 youíd 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 90 creates its own wireless connection, so it can communicate with your device even in remote locations where WiFi or cellular networks arenít available. Getting ready to observe is quick and painless thanks to Celestronís 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.
