Astrophotography without a PC or laptop! 

ASIAIR PLUS is a smart WiFi device. It has a lightweight power management module, ample USB interfaces, and multiple dovetail mounting methods.

With the rich features of the ASIAIR App, the whole procedure, from device integration to image capture, runs remarkably smoothly.

ASIAIR PLUS is the third generation of ZWO that has been continuously improved and newly designed since the first generation of ASIAIR was released in July 2018.

Please note the ASIair PLUS does not include a power supply or power cable, so please get in touch with us for advice if you do not already have something suitable. 

Outstanding Features

1. Excellent craftsmanship, strong tactile appeal

Superb craftsmanship with a solid tactile appeal ASIAIR PRO shell is made of Aluminium and processed by CNC tech. After the surface is anodised, it protects the shell well and has a comfortable feel. The size of the whole machine is 92 x 67 x 35 mm, making its size and weight excellent, which can be easily grasped by hand.

2. Unique look and easy installation

The slot/port position of ASIAIR PRO is nice and symmetrical, with M4 and 1/4 inch openings on the bottom and the side. With the use of the dovetail, installation and removal are easy. 

3. Integrated power management, more storage space

ASIAIR PRO is equipped with a lightweight power management module. There are four DC 5.5 x 2.1 mm power outputs on the side of the body, one DSLR shutter release port, and two USB 2.0 and USB 3.0 ports each. The power supply is stable and reliable, the interface is rich and diverse, and the wiring is easy and orderly. It also comes with 20 GB of free storage (additional USB drives can also be used as required).

4. Enhanced Wifi

Included with the ASIAIR Plus is a built-in WiFi antenna. 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 replace your computer or a mount hand controller. With wireless technology, you can even control your astrophotography gear from indoors! The 2.4G/5G Dual-band WiFi network has an operating range of up to 20m.

ZWO has designed the ASIAIR Plus so that it can also be hardwired via an Ethernet cable to your home's WiFi router. This enables you to access the device anywhere within your router's WiFi range. There is no VNC or remote desktop; the ASIAIR can 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!

5. Ports and Outputs

ZWO has also added indicators for the four DC-12V outputs to the body ASIAIR Plus. These indicators and a function in the ASIAIR app allow you to check the power status quickly and monitor power consumption in real-time. You can find the app in all major app stores. The ZWO ASIAIR Plus also has 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 check the 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 data transfer, eliminating the need to pull out the SD card or the need for a card reader. Please note 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.

6. Recover Mode and eMMC

ZWO has included a Recovery Mode where the system detects faults and recovers if the ASIAIR Plus cannot boot up. This version of the ASIAIR has been redesigned with eMMC storage; there is 32GB of storage space and 20GB of 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: 85MB/s
  • Avg. Write Speed: 52MB/s
  • Storage Space: 32GB
  • Free Space: 20GB
  • Super System Stability: Reset Firmware and Auto Recovery




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, and then accurate focusing can be done through curves such as brightness and HFD. It can also be achieved 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 a 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 image (lower noise with calibration frames) target's stack while capturing.

Supported DSLR

ASIAIR PRO is a smart WiFi device that controls 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.

2. The items with an exclamation mark in the table above have yet to be verified by actual tests and will be continuously updated in the future.

Supported Mount

We have also been working closely with major manufacturers to complete bringing in the match of iOptron, Vixen, Rainbow, Avalon, Explore Scientific and other models (including some new models). The ASIAIR PRO can support hundreds of equatorial mounts from over 20 manufacturers worldwide. For details, please refer to the “ASIAIR PRO User Manual”.

Great bit of kit
12 October 2023  | 

ZWO ASiair Plus, Great bit of kit, but definately requires a lot of watching vids and reading threads to allow enough knowlege for linking and running the guide cam and Nikon Z6. main cam Eventually "got to the bottom of" connecting the Sky Watcher EQ5 to run in tandem with Synscan, which all works a treat. Now trying to master the guide cam and Z6 focus and polar alignment, then onto go to and stacking. Will get there in the end. Still the ASiair plus brings everything together on my handy android devices, working in the warmth, although a ZWO EAF autofocuser is an essential for cold outdoor use, will be my next purchase.

Brilliant bit if kit if you own ZWO gear
17 July 2023  | 

Convenient bit of kit which allows you to control all your ZWO gear in one place. A well thought out interface, but with a few peculiarities which you soon get used to. Contains programs to perform various stacking routines, plan observations etc. KStars can do the same but this is just so convenient.

A great product and superb service from FLO
15 June 2023  | 

I contacted FLO for advice on setting up a mini guider for my small refractor. Alex, Dave, Grant and James all responded to my many questions and helped me select a system. In the end I decided on a system based on the ASIAIR plus, with a ZWO mini guide scope and camera. They were very helpful and fast with their responses and it made the process much easier as I havenít gotten into guiding before. Just got round to setting up the Plus, (had a clear night at last ). The system seems to work well, Iíll probably now get a ZWO imaging camera so I can do everything from the IPad.

Canít fault FLO for their support, they made sure I had all the components and cables I needed, my only negative about the Plus is the lack of a good manual. Couldnít find anything on their website, in the end tracked down a pdf copy online, but why donít ZWO make one easily available? Plenty advice on YouTube though, had no real difficulty getting it going,

No good.

Doesnít recognise DSLR camera listed in tested . Will be returning . Waste of time .


We like to help so please contact us. We can then check and advise :-)
Some cameras must be in a certain mode to function and others may require a separate shutter release cable, depending on the model.

Simplicity in action
20 April 2023  | 

I have waited a while to write this review, I find first impressions are not always ideal and rushing to review based on a few sessions is not ideal. This little box over the last 6 months has totally changed my approach to Astrophotography and my output. It is very simple and intuitive to use and makes imaging all night while I'm in bed sleeping a breeze!
There are some things I would like changed, the ability to access through the native app when not on my local wifi is one, but these are relatively minor. Being able to polar align, plate solve, goto, image, focus and control filters all from my phone and have the ASIAIR handle file names that record the date, time, filter and exposure as well as FITS headers with scope and target info embedded is awesome. I know all of this can be done, and maybe even better using NINA but that means a whole lot more cables, a mini pc, power distribution box and from what I have seen a more complex workflow. This is just simple, select a target and it moves the mount to it, plate solves, adjusts to centre and turns on tracking. It controls guiding with PH2 multistage guiding and manages filters and focus along with cameras with minimal input. A joy to use.

A game changer...
08 March 2023  | 

As a relative newcomer to Astronomy and Astrophotography, it was evident that this would be a significant "sidekick" to help me on my journey.

As a former techie, I found the setup a doddle and like the simple UI. I bought this to work with an Alt-Az GTI (EQ) and realised I could streamline the whole shebang by simply enabling STATION MODE on both the AsiAir and Synscan apps. Both apps will allow you to set a fixed IP address which is key. I then configured the AsiAir app to use the IP addresses I'd allocated to these devices on my home network. This means that you just turn on both devices and the AsiAir or other apps can use the tools without the faff of connecting to the Synscan and AsiAir networks. It is a few moments work and requires you to enter your WIFI password for each device just the once.

This piece of kit is beautifully engineered and so easy to use. I bought the guidescope and 120mm camera bundle and am like a wee kid at Christmas.

I cannot recommend this kit enough - just buy it.

Thanks for sending my ASIAIR out to me super fast. So happy with it. Iíve connected all my equipment up to it and it all connected with no issues. Unfortunately I havenít tried it out against the night sky as where I live weíve had none stop clouds. Hopefully the skies will clear soon

I'm new to astronomy/astrophotography and found the ASIAIR PLUS during a period of frustration when trying to execute a session, which then became a massive problem-solving exercise with nothing to show for it. Naturally due to the British weather, I've not used it to image as yet, although everything connected to it works flawlessly and its easy to navigate with plenty of YouTube tutorials online. Definitely recommended if you want to massively streamline your workflow. FLO have been excellent as always!
