A healthy 1.5 hours of integration time is enough to reveal fine whisps of interstellar dust illuminated by the Seven Sisters, despite bortle 6 skies. The plan is to use the long autumn nights to capture more data on this target. Thereby revealing more detail and diminishing noise levels. Getting out to a dark site at some point in the near future would be a good start!
