Great effort with plenty of data
Well done !
One observation was that all the images I’ve seen of Gum15 , the blue areas in the centre of this nebula are really really faint , you can just make it out with the majority of surrounding gasses Red Ha dominant
Maybe you pushed the core to hard in processing the colour bias ??
Still a great effort on a difficult and dim object
