Restoring a Backup on a Mac
Something else I came across and a chap called Terry on Facebook had a solution.
Again, you might already know this, but just in case.
You buy a new ASIAIR Pro, you are pretty much advised that one of the first things you should do, is to create a backup of your software(includes your license key) from the supplied SD card.
And one of the common methods suggested for Mac users is to use the “Apple Pi Baker” program/application.
So, I used the application to create my backup and saved it in a safe place, in fact I made two copies(belt and braces).
Then, yesterday, I thought I should really try to restore one of these backups to make sure they actually work, else what is the point of having a backup for that rainy day.
And actually, I will keep the original safe and use my copy going forward.
So, I inserted a new blank SD card(Fat32) and started the restore process, letting it run its course.
Once it had finished, I did a quick eye ball to compare the copy to the original and all the files appeared to be there.
I then plugged the restored SD card back into the ASIAIR Pro, but the device would not start/boot up!
Just in case, I then reformatted another SD card and tried that one, but still no good.
I then created another backup from the original SD card(so all in all I had img and zip versions) and tried to restore them, the same result, fail.
On further investigation, it looks like this is fairly common.
Terry on ASIAIR Facebook group suggested downloading the file from the ZWO website, but then using your own License file.
I then used the ASIAIR PRO link above(from the “How_to_Restore_ASIAIR_OS.pdf” on line doc) to get the file.
First, keeping a copy of my zwoair_license safe of course(still on the original SD card).
The file is pretty large, unzips to about 31 GB and takes a while to download(9GB zipped) even on cable.
I then restored(using Apple Pi Baker) this new downloaded file to my new SD card and once it had completed, I then overwrote(replaced) the
existing “zwoair_license” file with my original(my unique supplied copy).
Next, I then inserted the new copied/restored SD card into the ASIAIR Pro and it started.
Finally, I then connected via the ASIAIR app using my IPhone and was prompted to update the firmware to the latest version which I did.
Bingo all good, the original SD card supplied by ZWO stored in a safe place and I am now using this copy going forward.

This setup is awesome. A few years ago such an image just could’ve been taken with a monochrome ccd.
Have anyone tried to make a DIY version of hand controller for zwo eaf focuser? Or tried measuring what is the output of the controller?
I want to print a hand controller +battery case all in one but unfortunately do not have the controller to check what needs to be outputted thru connector. I assume it will be pretty basic like shortening contact but maybe someone has already checked
Thanks for looking!
Because of the current situation, I have, as many of you guys probably have too, spend a lot more time under the stars when possible.
It has literally been over a year since last I was out doing some astrophotography because of work.
So here is my second take after the long break, NGC 3344 (The Sliced Onion Galaxy).
Initially I thought it would be a lot fainter than it was, so it was basically a shot in the dark, of just trying to get back at doing this.
But the final image actually showed a lot more detail than I would've hoped for!
Spring lent a lot of clear night, but those seems to be gone already. I would've hoped for a few more hours to add some more luminance data to it, as I did have to push it quite a bit.
I am not too happy with the shape of the stars either. Guiding was not very stable through the night, even though balance and polar alignment seemed to be good. Might need to update my Celestron PEC data?
Any advice or feedback is very welcome! 🤩
