Celestron Astro Fi 90 mm Wi-Fi Refractor

Celestron continues to change the way we interact with the night sky in new and interesting ways with their latest new scope, the Astro Fi 90 mm Refractor. It's a Wi-Fi equipped refractor that combines revolutionary new Wi-Fi control systems with tried and tested Celestron Optics for an absolutely stellar quality item! Replacing the traditional hand controller used for most automated telescopes is a free App for your Smartphone or other Wireless device called SkyPortal by Celestron. This means that you can control this telescope just as extensively from your phone, if not more so than you could from an old-fashioned manual hand controller!

As a further plus, the Astro Fi produces its own wireless connection, meaning that you'll always be able to connect to your telescope to control it, no matter what area you're in! 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.

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. So please, take advantage of this stellar opportunity to widen your horizons with this scope- perfect for any novice, or anyone interested in a simpler/ easier astronomy experience!


Lens Cap/Smartphone Adapter – Image celestial or terrestrial objects with this smartphone adapter! The Astro Fi lens cap has an integrated smartphone adapter to capture great images of the Moon, planets, and terrestrial targets like birds and wildlife. With its light, rigid frame, this accessory allows you to connect any smartphone to any telescope eyepiece with an outside diameter of 45 mm or smaller. This smartphone adapter installs easily over the top of an eyepiece while bungee cords securely hold your phone in position so you can snap images or video.  While the vast majority of smartphones can be used with the case on, some very large and/or bulky phone cases (such as folio style cases) may need to be removed for the phone to fit in the adapter.
