I was imaging narrowband over the last few nights, and was really wishing for a gain option in the capture module. I was imaging Ha at 200 gain, and wanted to do OIII at 300 gain, and had to do them in two sessions over two nights instead of the same night. I like to raise the gain for OIII since it's more difficult to image. Then obviously, when generating darks and bias, then I had to do them over two sessions as well, rather than setting them up to all run at once.
