Computerised Alt-Azimuth telescope: Take in the sky with the computerised 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.

SkyAlign Technology: 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.

Two eyepieces (25mm and 10mm), a star diagonal, an integrated smartphone adaptor, 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 centre an object in your eyepiece for easier observing.Accessories Included: The Astro Fi 127 comes with

  • Lens Cap/Smartphone Adaptor – Image celestial or terrestrial objects with this smartphone adaptor!

This smartphone adaptor 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 adaptor.
