    Full Features of the ZWO ASIAIR Plus

    A built-in WiFi Antenna

    It can greatly increase the WiFi signal compared to the ASIAIR Pro, making the WiFi connection between your device and ASIAIR Plus more stable. The signal range will also be wider.

    Four newly-added Indicators for the DC-12V outputs

    There will be a new update of the ASIAIR app when the ASIAIR Plus is released and you can check the power status easily and monitor consumption in real-time.

    Newly-added Type C USB Port

    It will allow you to directly connect the ASIAIR Plus device to your computer via USB cable to transfer data, instead of pulling out a SD card and using a card reader to transfer data.


    Smaller and Lighter

    Compared to ASIAIR PRO, the ASIAIR Plus has made some big changes in its appearance and weight: 24% thinner and 13% lighter. The ASIAIR Plus is made out of aluminum and processed by CNC tech, which will effectively prevent the ASIAIR Plus from dust and dew, also making the whole device sturdier and more durable. The top uses laser carving technology to show the constellations of Cassiopeia, Ursa Major, and Ursa Minor in the sky.


    ASIAIR OS runs on eMMC storage

    The new system will provide a smoother and more stable using experience. We also added a new feature: Auto Recovery Mode – When the ASIAIR Plus cannot boot up, the system will detect the faults and recover by itself. The internal storage of the ASIAIR Plus that is available for saving images and videos is 20GB.

    Why You Need the ASIAIR Plus

    It can totally replace your computer, and the hand-controller of some supported mounts to do astrophotography.

    It allows you to wirelessly control your gear via your smartphone or tablet. You can stay inside with your families and still enjoy the fun of astrophotography at the same time.

    It provides an integrated and easy-to-use workflow suitable for all astronomy amateurs. Even if you are new to astrophotography, you can use it to produce wonderful astrophotography images quickly and with ease.

Incredible all in one control

Running Cem26 zwo camera and guide scope, no focus or filter wheel or dew heater. Pretty intuitive menu. Got the hang of it by the end of the night. Love this thing.

OPT comes through! The much sought after item was delivered much faster than originally quoted!!

I am still learning the workflow and nuances of the ASIAIR Plus.

AsiAirPlus purchase

I knew there was a backorder on this product and the site gave an estimate of 2-3 weeks. I recieved regular updates from OPT about the delay, and was very happy to Hear that my item had shipped well within Their estimated timeframe. I'm new to OPT, and the great service they showed me is why I'll continue to use them.

An AMAZING device, with some quirks (you can lose pics!)

OPT was awesome as usual, enough said. I love this thing. I had to use my laptop a week ago and forgot how much it sucks compared to the ASI AIR. Pros: 1. Polar alignment works great, but very touchy. 2. Plate solving is unbelievably accurate and simple. You can also recenter the frame accurately by holding on the spot you want. 3. Guiding is amazingly easy to use. 4. Live stacking is simple to use. Cuiv the Lazy Geek has a great video on it. 5. You can set up a shooting plan and go to bed. It can park the scope and shut it down. Cons: 1. The biggest headache is the iOS app if you use an iPhone. It won't work with the latest iOS build and the built-in wifi!!!! I had to use an old phone with iOS 14.xx 2. The wifi is unbelievably anemic. Purchase a better antenna (2.4ghz and SMA connector) on Amazon. It makes a huge difference. 3. If you forget the SD card and use the internal memory, COPY THEM TO THE SD CARD, DON'T MOVE THEM! Twice now I've lost a whole session because they were deleted in the move. 3. You cannot set the camera's aspect ratio lower.

Has it's Moments, but there is Nothing Else Like It.

After struggling for a few months with a homebuilt Raspberry Pi computer, I gave up and purchased an ASI AIR Plus. WOW, what a major difference. It connects to my camera and mount, guides me through polar alignment and plate solving. There is nothing else like it.
