We at ZWO got some great news for you guys, where we announce that the ASI USB3.0 CCDs support Android devices. You attach the camera to the device’s USB and make sure that the device supports OTG.

Although the app is still in Alpha stage, with loads of bugs, crashes and misspellings, we strive to achieve feedback from you to improve the development of this app. You also can provide us some suggestions/wishes that we can apply within it that helps you to capture your shots. In that case, send your thoughts to:feedback@zwoptical.com


Above you can see a preview of a working demonstration between a Vivo X9 phone and an ASI1600MC CCD. You simply attach the cable to the CCD’s USB3.0 port and to your device’s mini-USB port, enable OTG in the settings so the device finds the CCD, installs all the necessary drivers to run it, start the app and start using it.

Smartphones are not the only Android devices which this app works with. We are making it possible to run it with a portable projector as well, where you achieve up to a 180 inch resolution of what the CCD captures. No need for large and heavy clumsy monitors or laptops for public displays.


Demonstrations below:



A short video of how it works to run this with a projector: https://youtu.be/KysgIQ7CksE

We are changing the way of astronomy and wide-field photography for public audience with this new technology of ours and we sincerely hope you will enjoy it as much as we enjoy of making it for you. The projector and CCD together weighs approximately 800 grams while the entire set of a monitor, laptop, CCD and all the necessary cables in between 8 to 40 kilograms. That’s a lot of spare weight with this app of ours, don’t you think?

ASI CCD with USB3.0
Android 4.0.3 or later
USB OTG (On-The-Go) support on Android device
