The film scans well. There is a lot of data deep in the shadows. There is a green cast to the underexposed film, but this can easily be removed with PixInsight. The well-exposed areas don't have this problem, so it's important to mask out these areas to just effect the dim stuff.
For a 20 minute exposure under poor skies, this is pretty good.
This picture won't win any awards. There are too many technical faults that I see.
The strong Ha response really blows out the color balance. I look forward to trying this film without a light pollution filter to see how well it does on a darker sky. I played with bringing the saturation and luminance of the red colors down a bit in Lightroom.
