Thank you ANJO.
Can you give me example of how to start exposure with indi_setprop? Probably there is domentation somewhere that I should have read?

Finally I can help at least a bit, I do not know how ekos is translating RAW frames, that Jasem might know but I my self use this python script, but it uses openCV, i guess we can do it without that :
I will redact code as I use openCV to detect object and crop it. This is used for PACKED mipi, for unpacked, we do not need this part of unpacking code.

save_image(imgCrop, os.path.splitext(outputPath)[0] + ".tiff")

Yeeeeee, OUTTA I'm glad that you solved issues with your device. I think we are making good progress here. I'm can't wait to put my HQ cam finnaly to test under clear skies and do some long exposure test!
