  • Preview and Focus in Real-Time.

Product Details

  • 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.


    • Cameras: Compatible with all recent ZWO cameras, as well as some Canon & Nikon DSLRs (with correct shutter release cable).
    • Mounts: Compatible with most equatorial mounts with the correct cable, often a EQDir cable. For a detailed list, please see the ZWO ASIAIR Pro manual.
    • Focusers: The ASIAIR Pro is only compatible with the ZWO EAF.
    • ASCOM/INDI: The ASIAIR Pro is not compatible with ASCOM & INDI drivers, as it is limited to the above.
    • For more detailed information on the ASIAIR Pro's compatibility, please visit ZWO's website or contact us.

Great combination

I love how simple and portable this combo makes an astrophotography setup. ZWO is constantly updating the asiair's software with really nice updates. There are still a few quirks that I am sure will get corrected in short order. I had to use an external access point as the built-in wifi antenna just isn't sufficient for my use. That is primarily the reason this is not a full 5 stars in my review. I would recommend this combo for its value.

Basically a waist of money

Well every word is towards how easy this makes astrophotography!..Not!!..Doesn’t give you any help in setting up your ZWO cameras so there’s that.You must already know all the settings before using this device so use sharpcap to set up your camera.Now update today and it will no longer connect to my mount!..It seems more like a toy and most of the mounts it uses are the high priced ones.It actually did a better job focusing my DSLR camera better than the ZWO camera ...So finally tonight after two weeks if clouds I’m ready to take some pictures.Then it updated the firmware and now it is a box with pretty lights that doesn’t work on my mount.I will be running my camera through the mount skywatcher app and focusing manually using dslr tonight Same setup before I purchased the ASIAR PRO. I don’t know who is writing the reviews but if your new to this hobby this will not help you learn the ZWO cameras and good luck connecting the mount!..

ZWO ASIAIR PRO imaging success.

I had so much success imaging with my first ZWO ASIAIR Pro, I decided to order a second unit for another telescope. Now I can quickly change scopes without remounting the hardware. Capturing images is really enjoyable and it’s easy to experiment with new techniques as my skills evolve. Great purchase. Quick and reliable delivery from OPT.

Reduced the complexity of my set up

Migrated from a Raspberry Pi running Astroberry and laptop as terminal. No longer need 110 V. power to keep my laptop going all night. Using an iPad now and love it. Purchased a ZWO EAF to go with it and last time out was polar aligned, focused, plate solved to my target galaxy, and live stacking in 23 minutes (not guiding). If you can go all ZWO, I really recommend the ASIair.

Using with Star Adventurer for Guiding

The ZWO ASI120MM Mini the the 30mm f/4 Mini Guide Scope works awesome for help with guiding the Star Adventurer to keep the stars from trailing with a longer focal length lens. Shipping was quick and packaged very well. No regrets purchasing from OPT.
