This is an experiment of sorts. I took the Ha and OIII data and stretched them with the Delinear script in Pixinsight. Then I loaded each as layer in Photoshop and then used GradientMap to map the OIII data to a bluish color I liked and then mapped the Ha data to a golden color. I set each layer to 'Linear Dodge' and blended them with a background solid layer set to (18/18/18) RGB.
