The Astro Fi series of Celestron telescopes all feature integrated WiFi, making it possible to control the telescope from your iPhone, iPad, or other smartphones and tablets compatible with the free Celestron SkyPortal app. You’ll be able to connect to your telescope even when you have no other cellular network or WiFi available because the Astro Fi 90 creates its own WiFi connection.

Award Winning Technology

Time is of the essence when observing the night sky, and Celestron knows this. With SkyAlign technology by Celestron, preparing to observe is painless and quick. To calibrate your positioning, you’ll simply focus on three bright objects in the eyepiece and the telescope will do the rest to calculate your position. For your enjoyment, you can then create a Sky Tour of all the most exciting celestial objects to view based on your time and location.

Trusted Celestron Optics

While telescopes are constantly having new features added and new technology is being innovated, it’s the optics inside the tube that truly make it a Celestron. For more than 50 years Celestron has been on the forefront of optical technology. All of this experience has been put into the Astro Fi, creating an experience complete with WiFi, fully coated optics and a 90mm refractor. You’ll never want to use anything other than a Celestron again!
