Review of the original ZWO ASiair:

"The ASIair is lightweight and compact, and designed to be fitted on or near to your telescope with hook and loop pads. With so many useful features it is difficult to accurately describe its functions in just a few words, but basically it is a stand-alone computer that can control ZWO cameras and a filter wheel, provide Wi-Fi connectivity to a mount, and auto-guiding. 

Not only is the ASIair unit itself nicely made, the app that controls it is slick, well designed, and simple to use. Astronomy software can become complicated and having to navigate overly technical applications in the dark with cold hands is fairly daunting. 
​This app is a pleasure to use and provides almost everything you need to know on one screen, including image progress, guiding graph and image preview. There's a histogram stretch, to give an idea of how much faint signal the camera is collecting. Colour images can be debayered - where colour filters are adjusted - while you are on the move."

The slot/port position of ASIAIR PRO is nice and symmetrical, with M4 and 1/4 inch openings on the bottom and the side. With the use of the dovetail, the installation and removal become easy. The whole machine adopts bright vibrant Ferrari red tones, and the front is painted with laser star maps of the constellation Ursa Minor and Ursa Major, which is very beautiful.

3. Integrated power management, more storage space

ASIAIR PRO is equipped with a lightweight power management module. There are four DC 5.5 x 2.1 mm power outputs on the side of the body, one DSLR shutter release port, two USB 2.0 and USB 3.0 ports each. The power supply is stable and reliable, the interface is rich and diverse, and the wiring is easy and orderly. It also comes with 84 GB of free storage, so you can capture images freely.

4. LED indicator, clearly indicates the working status

The LEDs will show the working status clearly. What’s more, it has the key operation warning tone, which makes the whole operation under control.

App Functions

ASIAIR supports both iOS and Android systems.

基本 RGB

1. Simple APP interface, as easy as 1, 2, 3.


2. Accurate focus: After the rough focus is completed, select one star, then accurate focusing can be done through curves such as brightness and HFD. It can also be completed with ZWO EAF by remote control.

3. Polar Alignment: Based on the powerful plate-solving function, you can finish arc-second polar axis alignment only within few minutes.

4. Accurate GoTo: With the rich celestial object database, precise GoTo can be achieved after selecting the target.


5. Stable guiding: Independent and stable guiding can be achieved without the PC.

6. Preview mode: You can see the image of the target directly under ‘Preview’.

7. Autorun: Set the target and configure the schedule, ASIAIR will execute the imaging sequence automatically.

8. Live Stacking: You can see the stacked image (lower noise with calibration frames) of the target directly while capturing.

Supported DSLR

ASIAIR PRO is a smart WiFi device that allows you to control all ASI USB 3.0 cameras, ASI Mini series cameras, and Mainstream DSLR cameras. (It can not support ASI120MM/MC camera)


1. Some DSLR cameras have a 30-second exposure limit, which requires an external shutter release cable to ASIAIR PRO.

2. The items with an exclamation mark in the table above have not been verified by actual tests and will be continuously updated in the future.

Supported Mount

We have also been working closely with major manufacturers to complete bringing in the match of iOptron, Vixen, Rainbow, Avalon, Explore Scientific and other models (including some new models). For now, the ASIAIR PRO is able to support hundreds of equatorial mounts from more than 20 manufacturers worldwide. For details, please refer to the “ASIAIR PRO User Manual”.

Great service and a great little device
Monday, 5 April 2021  | 

I used to use the original ASIAIR and once I got used to it everything was easy and minimal time wasted setting up. I switched to SGP in late 2019 and seldom does everything go as smoothly as with the ASIAIR, there always seems to be something which plays up and wastes me an hour before I can start imaging. So, I bought the ASIAIRPro so I can spend more time imaging and less time faffing about

Compact & compelling
Monday, 5 April 2021  | 

Great service from FLO, as I have come to expect.. I had some minor glitches with the Air disconnecting, but this was due to using a 12v (Halfords) battery to supply it. I happened to have a 12v, 5A adapter with the right connector on, I extended this with the cable in the package and end of problems. I run in station mode from my home network and I can control the scope (BT extender at the scope). From my living room 100 feet away. Plays well with Celestron AVX, ASI224MC on guide and ASI533MC as main camera. Such an improvement to work flow this has to be my number one imaging purchase. Point my Altair Starwave 80ed towards the pole, run quick alignment and then onto my iPhone. Polar align pick an object - goto followed by plate solve and centring. Saves so much time under all too infrequent clear UK skies.

Only just received it and tried breifly on a partially clear night. Seemed to set up easily and the app looked straightforward and easy to follow. Could not get the guiding to calibrate but that was probably down to me. The only down side for me was that the app dropped when trying to communicate from inside in rooms furtherest away from the rig which was set up in the garden.. (WiFi set on 2G).
Excellent service from FLO

Asiair pro

All setup and ready to go, a big fan of the original asiair so it was logical to go for the pro.
Not had a chance to try yet, but expect it to be as good as the original with loads of extras.

This write up was to say about how quick the delivery was, ordered Saturday afternoon delivered to my work first thing Tuesday morning.
Brilliant as always 👍

Brilliant little box of tricks
Monday, 8 March 2021  | 

Using a laptop outside always presents a few problems to overcome as well as having various applications to guide / image. Time to ditch the laptop and get one of these. Does everything I need it to in terms of polar aligning, guiding and imaging. The Wi-fi range may be small but I have a mesh system and when connected to that I have no issues with connecting from indoors (25 feet away). With regards to camera compatibility, check the ZWO website for a list, it supports canon and Nikon as well as ZWOís own cameras (doesnít support canon M series).

Thereís lots of support from the asi air facebook group if you get stuck or have questions.

As usual FLO were quick to dispatch (they were out of stock but I used their email reminder option, it notified me when in stock and I ordered immediately). Iíve ordered many items from FLO and highly recommend.

Donít delay, order one today!

Its a game changer but it could be better.
Friday, 5 March 2021  | 

This really is one of the best purchases I have made for astrophotography. Before, I used to lug my old laptop outside and I would try my best to polar align, setup guiding, gotos and focus across multiple apps. Now I can do all that from phone! As its more convenient, my polar alignment has improved (the PA tool is great) and my guiding has improved immensely and so has my photos

I could easily give this 5 stars, but once you start to use it more, you'll realise that this version has very limited wi-fi reach (much worse than its predecessor) that you'll need to compensate for with some wi-fi extender. You'll also realise that while it might have a lot of power outputs, they're not ideal to power the mount, the camera or the dew heaters, mainly because they might start to draw too much power and bring the photo session to an abrupt end.

Simplicity Itself
Friday, 22 January 2021  | 

I have been through a few iterations of trying to automate my astrophtography, from st4 autoguiding and simple shutter release on my DSLR through to integration with a laptop and a range of different software elements. I liked the idea of the ASiair pro to gelp tidy up the mess of cables and shorten my setup time, but didnt expect it to enable me to go from deciding its dark enough to start setting up to getting a galf decent shot of M31 in 15 minutes.

The simplicity of the set up is what really impressed me. I plug in my DSLR, Guide camera and mount, connect my tablet and install the app. Now select the devices in the app menu, decide to throw caution to the wind and do a preview and plate solve. Within seconds its telling me it knows what its looking at and do I want to sync with the mount, yes, give that a go. Now select a object to view, M31 cant go wrong. Again within a few seconds its telling im its slewed to the target and a few seconds later its centered M31, another preview and there iit is, not perfect but its a picture of M31. This was just a plonk and go, no polar alignment, no leveling, just point and go.

Next try guiding. Again in the past it would have taken 20 minutes to set up and calibrate, but with the the ASiair pro just click on guiding, pick a star and while I pop back into the house to find my hat, its calibrated and guiding on M31. Imaging session is just as simple, with no fuss (although I just did 20 lights, darks and bias will be included in my next session).

To sum up, I am really impressed with this little device, cant wait until the next clear night when I can see what else it can do.

ZWO ASiair Pro Wireless Astrophotography Controller
Sunday, 25 October 2020  | 

We bought the ZWO ASIair Pro as part of a portable rig that included the iOptron SkyGuider Pro, the William Optics RedCat v1.5, iOptron Ball Head, iOptron tripod and the ZWO mini Finder guider and ASI120mm - mini bundle. We ordered all at the same time but were aware that some had a longer lead time than others. Throughout FLO were brilliant at keeping us informed and shipped some items earlier than agreed because we were still waiting for the tripod. Previously we have only used a GoTo Celestron 8SE so getting used to the small rig has required some effort but there are some great YouTube videos out there to help and we now we feel we can write a review of the components.

The ASIair offers real freedom to portable astronomy and for that reason we would have given it 5 stars however we have encountered a number of difficulties and a certain amount of quirkiness in setting up and using the system; some of which could be explained by our inexperience in using the system but others may be bugs that haven't quite been ironed out. We have noticed that setting up indoors or in warmer weather the ASIair can run very hot. We have noticed that the system doesnít always connect to the local wifi, also there is little error notification so in the early stages it takes a quite a while to discover what the issue might be. We had problems initially with using the guide scope as this did not seem to function until we ran the demo guide scope first. There are occasional problems with the system not reading from the main camera (Canon DSLR) this seems to be rectified by changing to the guide scope camera taking a shot then returning to the canon but sometimes the ASIair needs restarting. We always switch the system off in the app but occasionally we get a white screen with the first canon image. That said we have had a number of nights where the system has worked perfectly and we love all the functionality from the polar alignment to plate solving and we are having a great time exploring the night sky Öwhen clear! There has been a recent upgrade to the ASIair firmware which allows for videoing for some cameras amongst other improvements. Unfortunately, as yet, the video for the Canon 80D is not supported.

Input from FLO:

It sounds like you are using the ASIAIR Pro in station mode connected to your home WiFi network rather than a direct WiFi connection over the unit's hotspot. This is great for stability if you have a strong enough WiFi signal where you are using the mount but if your closest WiFi access point/router is inside the house with the ASIAIR Pro outside this can cause connection issues sometimes. A WiFi access point located as close to the physical location of where you are taking photos is best. You can also try running it with a wired ethernet connection to troubleshoot this and verify it is a WiFi problem overall.

The issues reading from the main camera and connection of the guide camera are possibly related to to the driver for the DSLR itself, this may be resolved with an update but it's tricky to say for sure. If it performs without issues sometimes it's hard to know for sure where this might be occurring. The ZWO forums might be able to help here -

Since discussing this with FLO we confirm that all of our firmware was up to date but have noticed that by allowing the ASIair a little time to make connection with the home wifi the issue has settled down occasionally during a run it needs to reconnect but establishes this fairly quickly without loss of data. The forums and Facebook group are a good source of help.

It worked first time!
Saturday, 15 August 2020  | 

Usual great service from FLO. Gear arrived in great condition. I backed up the sad card then connected everything to the ASIAIR pro and tested the connections. All went well so I setup outside for a trial run. Did a quick polar align through the polar scope then made sure the main scope and guide scope were in focus. Ran the PA tool in the app and had an accurate alignment in less than 2 minutes. I then slews to M20 - The Trifid Nebula. The app platesolved and recentered the target perfectly. I calibrated the guiding done with the asi120mm mini - also new - which went smoothly. Started the guiding with 2 second exposures and took a 20 second test exposure with asi1600 mm cool. The nebula looked good so I did a final focus then set the app to auto run. It went through the sequence of 10x 3min luminance subs perfectly but Iíd forgotten to cool the camera! As I was just a test run I quickly reset the auto run to do 5xl, 3 each of r,g and b. All went well. I then shot 10x Ha which I thought might be better for luminance data. All 3 minutes long with dithering every 2 frames. I canít believe how well this all went for a first try. Hoping itís clear again soon to finish taking a lot more subs on this target. Very impressed with the ASIAIR pro. It powered my main camera, my heq5 pro mount and 2 dew heater straps. I used an eqmod dir cable without issues. I wasnít able to test the meridian flip but think it should be fine as the platesolve works so well and very quickly. Only downside for me is I donít have aZWO focuser so had to use the hand control to adjust rather than the app. If they add autofocus in future app updates Iíll probably add the EAF focus unit as this would be better for long sessions with filter changes. If you have a ZWO camera or a DSLR Iíd really recommend this unit.
