I have tryed to confirm, that I used right settings. For some reason, there is not anymore QHY imaging information in FITs header.
I remember, that it used to be there, least with QHY8.
I'm positive that Gain, Offset and temperature are same all the time.
How ever, there might be a possibility, that the download speed has changed, I red somwhere here, that the Lowest
speed is not supported with a Green board, I still use a Green one.
I might have changed the speed to "normal" in new driver for that reason.
I will test again in near future.
Can a download speed explane so great difference in ADU?
