I decided to declare victory and move on. The O-III is very dim and my Baader filters show their weakness here. Need the Astrodons.

Processing included de-staring with Straton, then adding back in the RGB stars with PixelMath after merging the de-stared Ha and O-III with Pixelmath in RGB ratio of 1.0, 1.2 and 1.3.
