Product Details

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

    USB 3.0 PortsThe 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.

    Manufacturer's Warning: Power output/inputs - DC 12V@5A (minimum Voltage is 11.5V; maximum supported current is 6A) with four output ports; 12V input is recommended and do not exceed 6A.  Too high of a current will cause overheating problems.

The ASIAir makes taking astrophotos almost too easy

I've been doing astrophotography since the days of the SBIG STV, the world's first auto guider without the need to use a computer (I still use one). While the STV took care of guiding, there were still a hundred things that I needed to do to my scope and camera get a descent photo. Enter its spiritual successor. With the Air, everything is easy, almost too easy. I use it to control my ZWO 533 on an AP Traveler on a Mach1 mount in my backyard observatory. It powers my cameras, polar aligns the mount, plate solves and centers any object I choose within minutes, autoguides and then shoots/dithers as many frames as I want. I can spend my time connecting with the starts by doing visual observing through my Obsession 18 while the system just... works by itself. Last night, the system took 15 flawless 5 min subs of the Leo trio. Now I just need ZWO to invent a device that automatically post processes these gorgeous images. The Air is going to allow ZWO to corner the astrophotography market. It just takes all the difficulties out of taking the images. Now the hard part is post processing. ZWO, if you are reading this, invent the ZWO Processor. Then my astro life will be complete. Sandy

Can’t wait to use!

Since I haven’t been able to use this yet, this is more a review on shipping. It arrived super fast. Cute little unit, hoping it will work with my mount ( when it arrives and ships? Someday?) In the mean time, I’ve backed up the unit and created an additional backup on a micro sd card. Simple and easy to do.

Fantastic device that is high quality. I've had three sessions with it with great success. The polar align feature is a breeze and dead on. I've been getting great tracking and able to shoot 5 minutes subs with zero throw aways. Only thing I had to really figure out was how to work it with my EQ6R mount. Once I got the EQMOD cable and bypassed the hand controller it worked fantastic. Also make sure you shoot in autorun and it will save your individual darks, lights, flats and bias. If you shoot while stacking it saves only individual lights with master flats and bias which you can't use in DSS.

ZWO ASIair Pro setup

Very easy to set up start using, will connect to my Canon T7i or my ZWO ASI cameras. Works well with my Orion Az/EQ 6-G Pro mount and slews to on app targets. Also parks to home position. Two problems : it doesn’t connect to my SkySafari Pro app and sometimes looses its connection to my wifi temporarily. I would highly recommend it to beginners or if you want a quick, light setup. Thank You OPT!!!

Great gadget, but there are things to know....

-you can't power your mount from the ASIair pro. The four power jacks provide only 2 amps each, and my mount takes 3.5 amps. I tried. It doesn't work. You could power cameras, dew heaters, etc if they take 12 VDC, but not the mount -It takes time to learn to use the app -Either the app or the device sometimes changes my longitude to an impossible location, E 247 degrees. Now you can't go farther east than 180 degrees, so I have no idea what its up to, but it does it and I'm not sure how to fix it. All that said, it's an awesome device that makes astrophotography much less of a chore and more fun.
