Here are 4 versions of Pacman (NGC 281) made with various combinations of HA, R, G, and B data. The latest versions at lower right uses HA for luminance, HA (for red), G, B. It looks a bit too salmon colored. I have no illusions about the quality of my work, but nevertheless this has been a useful exercise. I used an IDAS LPS filter while gathering RGB data, because all imaging done from my light polluted SF Bay Ara yard. I probably should have combined red with HA for the red channel rather than using HA alone. Suggestions most welcome.
