Interesting data, Ray. On a couple of occasions, when the data justified it, I have done two integrations of my luminance - one weighted for best FWHM and one weighted for best SNR. These are blended so that the high FWHM integration is used for the brightest parts of the image and the high SNR integration is used for the dim parts. It should be possible to do something similar with short subs for the high FWHM data, even with a camera that doesn't have incredibly low noise (like my KAF-16803...) Food for though
