Computerized Alt-Azimuth telescope
Take in the sky with the computerized alt-azimuth telescope. This straightforward design allows the telescope to move in all directions.
Integrated WiFi & Celestron’s SkyPortal App
Control your telescope using your smart device. The Astro Fi series emits its own wireless connection to Celestron’s SkyPortal app to provide easy remote observing. Celestron’s SkyPortal app replaces the traditional telescope hand control for a 100% wireless experience. Scan the sky for an object you would like to view, tap the object in SkyPortal and watch your Astro Fi telescope automatically slews to the object. While observing, SkyPortal provides information on the object; it’s never been more fun to explore the universe!
NOTE: Due to the amount of information SkyPortal has to offer, we recommend downloading the app before going out to observe.
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.
The Astro Fi 90 comes with two eyepieces (25mm and 10mm), a star diagonal, an integrated smartphone adapter, and a red dot finderscope. The two eyepieces offer different magnifications to view your intended object. The star diagonal provides a right-side-up viewing for a more comfortable viewing angle when looking up at the sky. The red dot finderscope will help you quickly center an object in your eyepiece for easier observing.
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 45mm 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.
