Why we love the ZWO ASIAIR PLUS 256GB (ZWO-AIRPLUS-256)

This is the third generation of the revolutionary ASIair now updated with 256GB of onboard storage! This is a smart wireless controller that will run your main imaging camera, as well as a guiding camera. You can also use the main imaging camera to polar align. In short, the ASIAIR Plus will vastly simplify your setup and astro-imaging process. It’s a fantastic tool for new and experienced astrophotographers alike.

Adding this camera controller to your astrophotography setup will allow you to control ZWO USB3.0 and ZWO mini-series cameras. The ASIAIR technology can also control the ZWO electronic auto focuser (EAF), nearly 100 Canon and Nikon SLR and mirrorless cameras, and more than 400 common equatorial or partial alt-azimuth mounts, all while you use your phone or tablet to capture astounding images of the night sky. The ASIAIR Plus requires a clean or dedicated power supply. We strongly recommend the ZWO AC to DC adapter found here.

Product Description

The body of the ASIAIR Plus is smaller and lighter than its predecessors. It is 25% thinner and 13% lighter than the ASIAIR Pro. The body is made out of CNC machined aluminum and the design of the casing protects the technology from dust and dew accumulation. With laser carving technology, the top of the ASIAIR Plus showcases a design with the constellations Cassiopeia, Ursa Major, and Ursa Minor. You will find several status displays on the body of the ASIAIR Plus: an Input Power Status Display (PWR), a Wireless Network Status Display (WiFi), and a System I/O Status Display (SYS).

The dimensions of the body are 102.5 mm x 70 mm x 26.5 mm

About the Enhanced Antenna and WiFi Capability

Included with the ASIAIR Plus is a built-in WiFi antenna. When compared to earlier versions of the ASIAIR, the Plus version's antenna has an increased signal, making the connection between your device and the ASIAIR Plus more stable. This also enables the signal range to be wider. With the inclusion of the antenna, you will ultimately see a stronger WiFi signal and faster communication.

This small device can totally replace your computer or a mount hand controller. With the wireless technology, you can even control your astrophotography gear from inside! The 2.4G/5G Dual-band WiFi network has a working range of up to 20m.

ZWO has designed the ASIAIR Plus so that it may also be hardwired via an Ethernet cable to your home's WiFi router. This allows you to access the device anywhere within your router's WiFi range. There is no VNC or remote desktop; the ASIAIR is able to handle all tasks needed for DSO imaging. These include Preview, Plate Solving, Focus, Polar Align, Guiding, Autorun, Plan (multi-target), Video (Planetary Imaging, Live Stacking, and more!

The ASIAIR Plus Outputs and Ports

ZWO has also added indicators for the four DC-12V outputs to the body ASIAIR Plus. These indicators, along with a function in the ASIAIR app, allows you to check the power status easily, and you are able to monitor power consumption in real-time. You can find the app in all major app stores. The ZWO ASIAIR Plus also comes with two USB2.0 ports and two USB3.0 ports that will allow you to connect your ASIAIR device to your camera, mount, ZWO EAF, and more. Please make sure to check power requirements for any device you plan to connect

Also included are a gigabit Ethernet port and DSLR Shutter Release cable receptacle. The Type-C USB port allows for connection to a laptop for exporting files from internal storage and the TF card. This connection allows for the transfer of data, eliminating the need to pull out the SD card and the use of a card reader. Please note that a USB-C to USB-A cable is required, but not included. The ASIAIR Plus also supports external TF cards and USB drives for upgradable storage capacity. The storage capacity is recommended to be 512GB and 1TB maximum. It currently supports three file system formats: NTFS, FAT32, and exFAT.

Recovery Mode and eMMC

Get ready for a smooth and stable experience with the ASIAIR Pro. ZWO has included a Recovery Mode where the system will detect faults and recover itself if the ASIAIR Plus cannot boot up. Additionally, this version of the ASIAIR has been redesigned with eMMC storage; there is 256 GB of storage space and 240 GB free space storage for saving images and videos. With the eMMC, the ASIAIR Plus' I/O speed is up to 2.5x faster than the ASIAIR Pro.

eMMC Features

  • Avg. Read Speed: 121MB/s
  • Avg. Write Speed: 95MB/s
  • Storage Space: 256GB
  • Super System Stability: Reset Firmware and Auto Recovery

Recommended Power Supply Requirements

ZWO recommends that the ASIAIR Plus have an 11V-15V @ 2A-5A power supply. If the power supply is lower than 9V or higher than 15V, the ASIAIR Plus cannot be turned on as a safety precaution.

Good for Newbies

I'm new to Astrophotography and I find the ASIAIR is a very easy to use and worthwhile purchase.

Locked to ZWO CMOS cameras only

Purchased this not long ago. Extremely disappointed that everywhere I checked, there was never a mention that this device is "brand-locked", and you cannot use other CMOS cameras with it, which is ridiculous. That includes the description on this site and it should be updated. Before I bought my cameras, I tested it with my Skywatcher mount, and my DSLR, which it worked fine for, so I figured I'd be fine?
I've decided to keep it (because it's far easier to return the other cameras to Amazon for free than pay a 20% ridiculous "restock fee" and I'm swapping out my cameras for ZWO, since they are all new and there's no real good substitution for it yet. Because of this, in the future I will NEVER buy another ZWO product again.


Looks like it will be very easy to use. Unfortunately it has been cloudy sinse I received it. 😥


Absolute wonderful piece of equipment!
