This is a second attempt to process the first upload of my Sadr region image. My conclusion is that, given the data I was able to collect at my light polluted site, carrying processing further only degrades the image.
Here are the PixInsight tools I applied to this image: AutomaticBackgroundExtraction, BackgroundNeutralization, SCNR (remove green cast), HistogramTransformation, CurvesTransformation, MultiscaleMedianTransform (noise reduction first 3 layers).
Conclusion: It took a light touch with most of these tools to avoid making a marginal image worse. As a result, the background nebulosity (red) is barely discernable.
Critiques are always welcome.
