A first attempt at processing the Cone Nebula as HaRGB in StarTools. Big issues with stars - Ha small stars, RGB considerably larger so was getting lots of rings (I manually blurred these out as it only happens on the brighter stars) and the star colour shifted away from anything normal early on. Ended of using GIMP to rather freely colour the picture (a bit pink perhaps!). I wonder if I had too much Ha and not enough RGB (only 21 minutes of each, compared to 140 minutes of Ha) and whether RGB from light-polluted backyards is always going to be a problem?
