For even more fun, Astro Fi’s lens cap does double duty as a smartphone adapter. Position your smartphone inside the adapter and then secure it over the Astro Fi’s eyepiece to capture images and video of all your discoveries.

Schmidt-Cassegrain Optical Tube
The Astro Fi comes with a 6 inch optical tube, a great multi-use telescope with 1500 mm focal length (f/10). The Celestron C6 is equipped with patented StarBright® XLT coatings which visibly increase contrast on subtle lunar, planetary, and nebula details and higher light transmission for brighter deep space images and shorter exposure times. For this application, observers can use the C6 Celestron optical tube to view the night sky or as a terrestrial spotting scope. The Celestron C6 has the best balance of portability, handling ease, light grasp and price ever offered to the amateur astronomer. It is an advanced level instrument that is as easy to use as any intermediate level, and most entry level, telescopes.

StarBright XLT coatings
Schmidt-Cassegrain optical system offers bright, sharp views with StarBright XLT optical coatings—a great choice for visual observers and budding astroimagers alike. StarBright XLT is Celestron’s revolutionary optical coating system that outperforms any other coating in the commercial telescope market. There are three major components that make up our StarBright XLT high-transmission optical system design: Unique enhanced multi-layer mirror coatings, multi-layer anti-reflective coatings, and high-transmission water white glass. These three components of our StarBright XLT coatings result in one of the finest coatings available.

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!

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

Smartphone Adapter
Image celestial or terrestrial objects with this smartphone adapter! The Astro Fi has an 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.

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. Download the SKYPORTAL APP

Accessories Included
The Astro Fi 6" comes with two eyepieces (25mm and 10 mm), a star diagonal, a smartphone adapter, and a StarPointer 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 StarPointer finderscope will help you quickly center an object in your eyepiece for easier observing.

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.

  Great customer service   I bought this Astro f1 6 telescope a few weeks ago had a problem with the WI FI. Contacted Harrison Telescope who, after trying several ideas, decided there was a fault in the mount head.They arranged to replace it the next day and collect the faulty mount. All at no charge. Recommend.  (18/05/2022) William - Tewkesbury
