I revisited M27 over four nights as the first target of my automation. It took that long because I had to work out several of the automation glitches, but I finally assembled all the exposures that I needed. The specifics are listed below and I would welcome any suggestions. The colors have not had any artificial adjustment of hue. This is the color that came out of the combine.
