Celestron is not only changing the way we experience astronomy, but we're also changing the way you interact with the night sky. The Astro Fi 102 mm Maksutov-Cassegrain is a fully featured telescope that can be controlled with your smart phone or tablet using the free Celestron SkyPortal app. 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! The Astro Fi 102 creates its own wireless connection, so it can communicate with your 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. TRUSTED CELESTRON OPTICS Innovative WiFi technology powers the Astro Fi, but it’s the optics inside the telescope tube that make it a Celestron. For over 50 years, we’ve led the industry in optical technology—and we put that experience into the Astro Fi 102. This 102 mm Maksutov-Cassegrain with fully coated optics 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.

-Light Weight, easily to pack and set up (done in about 2 minutes)
-Once you master the fairly easy software you can be tracking objects quickly
-No more typing in coordinates and time of day as the scope uses your phone for all that information
-No wires from a hand controller to get in the way or worry about
-Clever built in eye piece phone holder for group viewing and taking photos (it is built into the main optical lens cover making the lens cover dual purpose)
-It can also support a hand controller if that is what you are used to
-Easily Fits in a backpack and the stand will strap onto the backpack for a really portable scope
-Unlike other Celestron Maskutov scopes you can NOT remove the scope from the stand and use this scope as a table top scope. This is the biggest negative for me and why I gave it 4 stars
-The plug for connecting power is very cheap and it could break if you snag the power cord while slewing
-It does NOT come with a 12 volt AC power supply or batteries
Overall this is a really nice scope due to it's wifi feature, light weight and ease of use. Your first time using it could take some time to get set up and gain an understanding of the alignment procedure. It would be nice if it was able to be used on tabletop. I may just have to custom make a table top stand for it.
This video was taken on a very cloudy night with an iPhone attached to the built in phone holder on the lens cap. Stock 45mm lense with no filters.
plastic and the finder scope could not be aligned or used. By just spending $100 more you get:
1) Excellent all metal build quality including thumb screws for swapping lens & accessories
2) a finder scope (only thing plastic besides lens covers) that actually works very well
3) AND you also get WiFi and Skyportal for your cell phone to align scope and then with its great graphics touch and have the scope find and (most important) track an object
4) Has (in the case of the Astro Fi 90) a dew protector on front of the scope
Now on the reviews which frankly gave me pause/concern on this purchase.
We used two different brand (Motorola, Samsung) 3 year old $80 cell phones (one at a time). The WiFi worked from 50 foot away. The Skyportal app worked well on each. These phones are kept up-to-date but not crud-ed up with a lot of apps. The printed manual said to make sure the switch on the scope is to the left before connecting the cell phone via WiFi to the scope which is incorrect. Celestron has since corrected that and you will see it when downloading the same manual from their site. The switch should be set to the RIGHT and is set that way right out of the box. Each phone connected to the scope in 15 seconds after pressing the Connect and Align or Connect button on the phone’s screen. The Skyportal app lets you nudge the scope to center the item you are aligning if you slide the yellow rate slider towards the left. Batteries – still working after 5 nights of viewing about 6 hours per night.
I think the key is relax, be patient and take your time when aligning. After some practice/experience gained about 10-15 minutes total to align 3 separate objects (planet/star). Make sure to align the finder scope to the scope in the daytime per included instructions first. I've got it to a point where if the red dot is over the object it is centered in the lens. This alignment process is all worth it. Once done when you take a tour of the sky and touch an object (ex: Jupiter) on the phone's screen, the scope moves to it and stays centered in the lens even after a hour. One time the connection dropped – I just ended the app; started it back up on the same phone that alignment was done; reconnected and didn’t have to do the alignment again.
The term beginner’s means you will see planets in our case of light polluted skies from Saturn (and its rings) to Venus and the moon is awesome. You can also see Jupiter’s moons and brown ring clouds. If you want to see galaxies or nebula you need to go to the $1000 range for an 8 inch or more aperture scope. But the money saved allows for buying accessories (lens, etc.) that also work with the more expensive scopes.
This review based on Astro Fi 90 scope purchased on 7/2019 at $289 to celebrate 50-year anniversary of man landing on the moon. Planet viewing from Pgh PA. Celestron seems to improve their products so some other reviews might be for scopes purchased before this date.
10/1/2019 - Update
Telescope continues to work well - no problems to report.
Captured this picture of the moon with the included 25mm lens and purchased Smart Phone Adapter accessory.

I am very experienced with technology and was recommended this telescope as a great amateur telescope to start with. I would not recommend this product, simply down to the poor implementation of the App, the WiFi and level of troubleshooting support that is available from the manufacturer.
I have opened a ticket with Celestron to see if they can support. Otherwise it is being returned. Absolutely heartbroken and disappointed.
A few people on here complained about the WiFi signal (connecting your phone to the motorised mount) continuously dropped out. I haven’t had this problem. When connecting your phone I suggest going into you devices settings and select the scopes WiFi network (Celestron whatever..) before attempting to connect via the App. Aligning the scope is then fine provided that you go into App’s settings and select “manual align”. This avoids the scope doing all sorts of weird things during the alignment process. It’s easy to manual align - all you have to do is steer the scope to a total of three known stars, moon, planets and then you’re done. After that you just tap on the celestial object you want to see and the telescope moves automatically to it. Brilliant!
Have fun all. Well worth the money.
I’m going to try again but if it does not work unfortunately this will have to be sent back as it’s too much money for something that does not work as described. If I can get it working I will also update this review and rating.
Note the rating as my pictures of the moon were amazing. So there is nothing wrong with the scope just the mount.
Update. Read that the align issue was as the scope may not have been level. Not sure how to fix this as no level on the tripod.
Did try again the following day and after 3 hours of trying and failing to connect to the mount it was boxed up and sent back.
I’ve bought one with a keypad and no WiFi plus a level on the tripod. I’ve gone for the nexstar 90 SLT which I had considered first but was £100 more. Luckily it’s been reduced to only £40 more than I spent on the Astro fi now.
Assembly is straight forward, instructions are barely adequate. Honestly, I'd look for a better product.
Waiting for a solution from customer services.
The optics are good. Will mount it on another tripod for now and see how clear it is at night.
Unfortunately I’ve had to return the item on the advice of the seller.
