Hi,

I don't know what to do now. I just tried again, it's cloudy and sowing and I take a picture of a white wall. One time it is too dark, then too bright. ???

Hi,

thanks for the log - it looks like SharpCap is getting stuck trying to find the right brightness and keeps trying in the 320 to 360ms range, but can get a brightness of 57% and 72%, but never anything in the 60-70% range.

It may be that the camera doesn't support smoothly varying exposure in this range - for instance maybe you can only get 0.25s, 0.33s, 0.4s, 0.5s and the ASCOM driver picks the closest supported value. That would be awkward :(

I can also see some glitches in the exposure finding code in SharpCap, so I will definitely look into those
