Celestron Astro Fi 90 Wi-Fi Refractor Telescope - 22201

Classic refractor optics with Celestron quality with the latest wi-fi operated goto mount controlled via your smartphone combines in this superb package for discerning astronomers wanting the best from their investment. Celestron isn’t changing the way we experience astronomy, but is definitely changing the way you interact with the night sky. The Astro Fi 90mm Refractor is a fully featured refracting telescope that can be controlled with your smart phone or tablet using the free Celestron SkyPortal app.

Smartphone App Control

Celestron’s SkyPortal app replaces the traditional telescope hand control for a 100% wireless experience. Just hold your smart device up to the night sky. When you find an object you’d like to view, tap the screen. Your Astro Fi telescope automatically slews to the object, while the screen displays information about it. It’s never been more fun to explore the universe!

Accessories Included

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.
