Celestron Astro Fi 102MM Maksutov-Cassegrain TelescopeCelestron isn’t changing the way we experience astronomy, but is definitely changing the way you interact with the night sky. The Astro Fi 102mm Maksutov-Cassegrain is a fully featured telescope that can be controlled with your smart phone 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. It’s never been more fun to explore the universe!
The Astro Fi 102 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 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.
TRUSTED CELESTRON OPTICS
Innovative WiFi technology powers the Astro Fi, but it’s the optics inside the telescope tube that make it a Celestron. For over 50 years, we’ve led the industry in optical technology—and we put that experience into the Astro Fi 102. This 102mm Maksutov-Cassegrain with fully coated optics offers dazzling views of craters on the Moon, the rings of Saturn, the Great Red Spot on Jupiter, the Orion Nebula, the Hercules Globular Cluster and so much more.
