Review of the Celestron Astro Fi 90mm WiFi Telescope
The Celestron Astro Fi 90mm is a 90 mm refractor telescope from the reputable supplier Celestron. This 90 mm refractor telescope comes with fully coated glass optics, which provides satisfying views of the Moon, planets, nebulaes and more.
The Astro Fi has its own mobile-app and integrated WiFi, which makes finding sky-objects incredibly easy and inspiring. We were thrilled when we got our hands on one of these, so thrilled that it got featured in our review of the best telescope for kids in 2018.
However, don’t make the mistake of thinking that this telescope is only geared towards kids – as we have experienced first hand, adults can get a lot out of it as well!

Pros of the Celestron Astro Fi 90mm
The most obvious advantage of this telescope is that it is extremely easy to use.
You’ll need little to no knowledge of astronomy and stargazing to make use of this telescope, and it is therefore very suitable as a beginner telescope.
The reason why it is so user-friendly is the integrated WiFi. On behalf of this very handy feature, which can be paired with Celestron’s Sky Portal App, you can control the telescope without having to touch it at all. All you have to do is to point the smart phone to the sky. When you find any sky-object you want to investigate further, just touch the screen. The Celestron WiFi Telescope will then automatically slew to the object, while you get detailed information about it on your smart device.
Our list of the pro’s of the Celestron Astro Fi 90mm is:
- Extremely beginner-friendly: Based on the integrated WiFi, paired with the SkyPortal App, this is one of the most beginner-friendly telescope we have reviewed so far. And don’t worry, The Astro Fi creates its own wireless connection, so it can communicate with your device even in remote locations where WiFi or cellular networks aren’t available
- Guided tour: You can also an automated Sky Tour based on your exact location.
- 90mm aperture: The Astro Fi is a 90 mm refractor with fully coated optics, which provide you with satisfying views of various sky-objects.
- Extra accessories included: A StarPointer finderscope, 2 Kellner eyepieces, and a mirror star diagonal is included with the WiFi telescope.
Cons of the Celestron Astro Fi 90mm
Allright, it’s time to look at the downsides to the Celestron Astro Fi 90.
Honestly, there were nothing specific we could put our fingers on when we tested it personally. The views we got of a variety of sky-objects when testing it were quite satisfying, given the market-price of the telescope. In addition to this, you get a good “bang for the buck”, based on the solution with the integrated WiFi and mobile application, which provides an innovative and user-friendly method to control the telescope.
But – as we always do in our reviews, we talked to other buyers of the Astro Fi WiFi telescope. After talking with the buyers, we discovered that the feedback was somewhat more nuanced than we expected.
Based on the customer feedback, the negative aspects of the Celestron Astro Fi 90 is:
- The Sky Portal Application: This is not an issue with the telescope itself, but rather the mobile application that comes with it. Some users have reported issues, especially regarding the aligning of the telescope through the Sky Portal App.
- The set-up: There has been some negative feedback regarding the set-up of the telescope, which can be somewhat confusing.
We would like to mention that the review team at Telescope&Sky did not encounter these problems. However, we publish our reviews to help astronomers buy a telescope that best suits their needs. We believe it would be ignorant to not pay attention to the negative feedback provided by some customers. If you are more interested in an established and well-tested telescope, check out our review of the Celestron 127EQ PowerSeeker Telescope.
The Celestron Astro Fi do have some great features – it comes with integrated WiFi, which made aligning and pointing out sky-objects incredibly easy. Well, at least for us. Some of the feedback from other customers states the opposite.
The telescope can be bought for a little under $350 on Amazon, which makes it a medium-to-low priced telescope.
The views provided by the Astro Fi are, as expected, satisfying. Celestron are known for their high quality gear, and this edition is no exception. However, as mentioned – be aware that the navigation with the Sky Portal App has proven to be kind of clumsy for some buyers.
