Hello,

I use ASI174MM (usb 3) as guide camera with ASI mini guide scope, in version 1.4.4 (I think) of the app ASI174MM worked ok. Used it as main camera to get focus and take preview shots, in guide camera section it would show up and I could select and pick stars (briefly even manage to guide), all in all worked fine.

Now that I have installed v1.5, camera is detected but if I try to take a preview shot (selected as main camera) I get a message that exposure failed (see screen shot below) and then it gets stuck at loading.
If I swap to DSLR as main camera, then can't even take shots with DSLR..I get message "can't stop immediately, please wait for seconds", see screen shot below.
Shutting down (soft shutdown) ASIAIR and restarting everything doesn't allow to take any shots in preview.
Only way I could get things back to normal is by deleting the APP and then reinstalling it.
If I then go back and select ASI174MM as main camera and try to take image, same issue and then only way to fix is delete APP

To confirm if ASI174MM camera is functioning...I connected it to my laptop and via firecapture I could see landscape and various objects, therefore camera works...

I have sent two runtime logs, ZWO, please have a look and sort this out.

Lastly is there a way to roll back to version 1.4.4 of the App and firmware that works and was stable?

Thanks in advance,

ps: still waiting to hear about the ISO selection using Nikon D3300.

Nihal.
