ZWO ASIAir Pro Wireless Imaging Controller

The ASIAir Pro hardware is based on the PI4 board and OS has been rewritten for that platform - there will be a code branch to allow ASIAir Edn 1 to continue development in line with ASIAir Pro. USB3.0 is now standard on PI4.

ASIAir Pro has 64 GB of built-in space and a 64 GB flash drive giving total storage of 128 GB. PI4 has 4 GB of RAM and a new CPU - 30% faster than PI3.

The unit is now housed in a CNC milled aircraft-grade aluminum housing The housing will have mounts to allow it to be installed on the finder foot and the finder/guide scope can mount on the ASIAir-PRO. ASIAir-PRO integrates simple power management with 4x DC outlets (3A each to 10A max total) - will be controllable from the ASIAir app (some ports will be PWM controllable for dew controllers).

It will have a DSLR shutter control line to control the snap socket on many cameras. It will support all the latest cameras and devices such as EAF. New software features for ASIAir-PRO have not been finalized yet - Autofocus/automated meridian-flips, Live stacking, and Auto-Focus are all possible! As ASIAir-PRO is a new software package PI3 boards will not support it - updated versions with non-PRO features will continue to be developed and released.

Definitely, the old generation of ASIAir will be supported with limited new features and bugs fix. Some features rely on the hardware performance will be only available on the ASIAir PRO. So we encourage users to upgrade to the new-generation to make astrophotography.

Key Features of the ZWO ASIAir Pro

Preview & Focus In Real-Time

The ASIAir Pro can preview images in real-time. It will de-Bayer images from a color camera and automatically white-balance images on the fly. You can also zoom-in on a small area and use the half flux width half diameter graph to perfectly focus your telescope. The ASIAir will also switch between automatic and manual stretching so that you can get the most detail out of your deep space images.

Independent Autoguiding and Imaging

Autoguiding with a portable imaging setup requires you to bring along a laptop, often with multiple programs installed to both successfully capture images and autoguide. Often with multiple programs installed for image capture and autoguiding. However, the ASIAir is designed to handle both autoguiding and image capture at the same time so you can control everything from a single smartphone or tablet.


The 32GB TF card comes with ASIAIR PRO software, providing 20GB of free space.

A 64GB U-Disk is included.

You may also use any size of storage device you choose.

Four USB Ports to control up to four devices:

USB 2.0 Ports
The ASIAir has two USB 2.0 Ports that allow you to control two devices including a German Equatorial Mount.

USB 3.0 Ports
The ASIAir has two USB 3.0 Ports that allow you to control two more devices including a German Equatorial Mount.



Mounting your ASIAir Pro device:

The casing has been designed to be mountable to the dovetail bar on your telescope.



The casing is made of CNC machined aluminum. ZWO has tested the device and found that the casing should have almost no effect on the Wi-Fi signal. 

The degree of heating the casing undergoes during use depends on its power consumption. The aluminum should help to dissipate the heat.


Software: The new ASIAir PRO software has amazing features. Two of these features are Live Stack and Automate Meridian Flip

At the moment the app, (ASIAir) is only available with iOS/iPadOS/Android, but through some emulators for Apple technology you can try to run the app on these platforms.

The old generation ASIAir will be supported with limited new features and fixed bugs. Features which rely on the hardware performance will only be available on the ASIAir Pro. ZWO encourages user to upgrade to this new generation for the best astrophotography.

This product is pretty revolutionary and a must have for astro-photographers. I use Celestron AVX mount with a Nikon D750 for the camera, and the ASI Air connected to both automatically without any gimicks needed to get the device to see either device. The app which controls everything is fairly intuitive and easy enough to pick up and get going. I had no idea how to operate the ASI Air pro at all before setting everything up and in less than two hours i was able to get my mount polar aligned, and accurate go-to's. The next night I was doing that in about 15 minutes. All without the need for a 3-star alignment process. Anyhow definitely worth money.

All of a sudden, there it was available!

Snagged my ASIAIR pro after a few quarantine months' worth of clear skies, debating if I needed this in my new life-long hobby. Unsurprisingly, it was unavailable for a while and then it was available. Booyah! Got mine. I've set it up. The ready tone is a bit annoying, as is having to scrounge for a 12V 5.5/2.1 car charging cable to power this box. Got mine online. But... well worth it. Now, of course, the heavenly powers noticed new gear arrived and naturally they have graced me with consistent cloudy nights. Womp womp.

Worthy upgrade

Having owned the first version this new version is a major update! Being able to manage all power connections for the ASIAIR simplifies my setup. Only one power cord is needed to power everything. The other enhancement of saving to thumb drive eliminates the risk of corrupting the OS in the micro as card. Awesome product!

Great way to do portable imaging

Imaging the night can be a very complicated and challenging task. This tiny box makes it all so simple. Software is powerful but simple to use, it uses a tiny fraction of the power required by a laptop, so makes portable power much easier too. Still waiting for clear skies to fully test, but everything seems to work really well so far. My wifi seems a bit weak so I will have to use mostly in hot spot mode. Soon the software will include support for autofocusing. With that update it will do everything I need for even my most challenging imaging. Seems like a bargain for $300.

I like it

I got this so I didn’t need to run cables back to the house and it did the job. I had trouble with my EOS T4i but turned out to be my camera was broken. Also my neighbors WiFi was so strong I couldn’t get signal for it in the yard, a powerful repeater solved the issue. I could probably connect to it in space now...

Quality at a great price

A bit of a wait with the slower postage of late but when it did arrive was impressed +++ at finish and design. Have done initial set up but still waiting for clear skies to get running properly.
