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."

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.

ASI Air Pro - Relatively Simple to Get Going
Monday, 5 July 2021  | 

So, as usual this was indeed delivered with clouds. Initial attempt at setup wasn't too fruitful, installed the app on my phone and powered up. First, power via an orion powerbank was insufficient to drive the mount, unit and the camera, so back to separate supplies for the camera. Next, try as I might I couldn't get the app to see the device even though I was connected to the device wifi. So, one for others to note is that the app opens with your mobile data connection first, turn off mobile data and you'll get the device hooked up straight away. Even though I've a decent sized phone the screens are a bit on the busy side and hard to read with my deteriorating eyesight! Though I reckon it'd be a challenge at 20-20. Swapped to a spare 7 inch tablet and that worked far better (note just a 4-star rating because there's no pc interface and the app isn't too intuitive). First light was NGC6960, after a minor bit of pfaffing finding it in the list of targets and setting up a plan it centered (solved) PDQ,. I'm not that sure about offsetting for framing, etc. I was just happy to get it targetted. Ran the plan and was pretty happy with the results - it held up far better than APT and PHD for guiding, frequent cloud interruptions and guide star losses, but it recovered and stayed on target. So, in summary, nice bit of kit that would be so much better with a decent pc interface.

Fabulous bit of kit once I worked out that using a EQmod cable was the way to go connecting to a EQ5 goto mount and Canon 600D. It makes astrophotography so much easier for a novice like me. Just input all the equipment details and you are good to go. I have never found polar alignment so easy and the very fact that it centres DSO's ready to photograph is such a bonus. This is the first time I have used auto guiding and it was a breeze using the Asiair Pro. I managed to capture 2 minute subs before it was time to pack up and the stars were pin sharp. I'm sure I can go much longer but this was a test run to work out how to use the Asiair and it has rained ever since. Wish I had purchased one sooner.

Everyone should have one
Thursday, 6 May 2021  | 

I got the ASIair Pro with a SkyGuider Pro for use with my dslr, tele lens and a basic tripod (while waiting for my proper scope and mount to be delivered). First night I tried it out I managed to polar align, focus, track and autoguide (in RA) successfully enough to get a great image of M51 with ~50 mins of data plus calibration frames. The wifi connected first time, the app updated the software to latest version very quickly and connected to my Canon dslr and ZWO guide cam. Test frames are easy, basically it works first time (unlike most tech stuff, at least in my experience!). The wifi connection to my home wifi worked perfectly first time too (a little surprising given the comments Iíd read online about this aspect).
My honest opinion: This is a fantastic gadget and, at less than £300, itís one of the few real bargains around in the astro equipment world.

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.

ASI air
Saturday, 20 March 2021  | 

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
Wednesday, 17 March 2021  | 

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.
