Yes, I had thought about that, too. But then the SDK will reply with an error.

I believe that this is what you were having in mind:

a) Select read mode = 1

b) Set frame size to some values that should be valid in the extended mode, like this



c) Take a photo



The error which I am getting seems to be coming from the SDK when it tries to set the ROI for the exposure.I'm starting to think that this all is more of an SDK problem and not so much the Indi driver. For what it's worth the SDK comes with this little test application that will connect to the camera directly and take a single frame. It's coming with the source code so it's compilable and I looked at that, too. And that runs into the same problem when I code it to run the camera in read mode = 1 and take a frame bigger than the maximum frame size of read mode = 0. I will ask in the QHY forum.

I did just notice from the screen shots that the driver thinks that my frame offset is at (36,28) where according to my inputs I have it at (0,0). That does more or less looks like a smaller problem within the Indi-qhy code.
