Re: Sensor Analysis ASI294c, e/ADU does not look right

Yeah that was it. Had some trouble running the sensor analysis. I had to run it with my flat panel at full brightness even though it said it was dangerously close to the minimum exposure, but if I dimmed it seemed to get in an infinite loop when doing the last run of the analysis where I have to put...

Re: Flat Frames Capture - impact of Dark Frames

Was about to post a question about calibrating flats and found this thread. In addition to the bias option, but be nice to be able to apply dark subtraction to flats.
