Key Features: Celestron Astro Fi 90mm Refractor Telescope

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 aren’t available. Getting ready to observe is quick and painless thanks to Celestron’s award-winning SkyAlign technology. Centre 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, they’ve led the industry in optical technology—and they’ve put that experience into the Astro Fi 90. This 90 mm refractor 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.
