This image is from data I captured in my suburban back yard over two consecutive nights. The first resulted in much higher s/n than the second night. So this image is an experiment in including higher quantities of data with lower s/n. I used Local Normalization in PixInsight to integrate based on a custom evaluation function that takes into account s/n weight, FWHM and star eccentricity.
