Description

Celestron's Astro Fi 102mm Maksutov-Cassegrain is a fully featured telescope that can be controlled with your smart phone or tablet using the free Celestron SkyPortal app. Although innovative WiFi technology powers the Astro Fi, it’s the optics inside the telescope tube that make it a Celestron. For over 50 years, Celestron has led the industry in optical technology—and they have put that experience into the Astro Fi 102. This 102mm aperture Maksutov-Cassegrain Astro Fi telescope model is perfect for terrestrial and celestial viewing on the go. The telescope 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 at night. In addition, the included star diagonal provides right side up viewing for using as a spotting scope during the day.

The Astro Fi 102 creates its own wireless connection, so it can communicate with your smart mobile device even in remote locations where WiFi or cellular networks aren’t available. 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.

Celestron’s SkyPortal app is not only changing the way you experience astronomy, but also changing the way you interact with the night sky as the 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! For more information about SkyPortal see >>here<<.

You can assemble the telescope, its accessories, and download the free SkyPortal app in just a few minutes, meaning you are ready to observe in no time. The adjustable tripod legs allow you to customise the telescope’s height to your liking. The total telescope kit weighs just 7.3kg/16lbs, making it perfect for impromptu observing sessions or transporting to a dark sky site or wherever life’s adventures take you. After setting your telescope up, getting ready to observe is quick and painless thanks to Celestron’s award-winning SkyAlign technology. You simply centre 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.

You can capture images and video of e.g. the Moon or wildlife using the Astro Fi’s lens cap which doubles up as a convenient smartphone adaptor as well as a dust cover. Simply position your smartphone inside the adaptor and then secure it over the Astro Fi’s eyepiece.

NOTE: Due to the amount of information SkyPortal has to offer, we recommend downloading the app at home before going out to observe.

Included Accessories 

General Accessories - The Astro Fi 102 comes with 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.

Lens Cap/Smartphone Adaptor – Image celestial or terrestrial objects with this smartphone adaptor! The Astro Fi lens cap has an integrated smartphone adaptor 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 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.

Starry Night Software - Download Celestron’s Starry Night Software and learn about the night sky, celestial objects, and how to plan your next observing session. Celestron Starry Night Software is the premier astronomy software package on the market, providing resources and knowledge to view our solar system and beyond.
