The above image is done in PixInsight using the Foraxx script then layering the RGB image over the Foraxx result. Some tweaks and cleanup in Photoshop.

Next is the image done "Old school" in Photoshop using layers and Lighten Blend Mode and toggling each layer's colour mapping to assign Ha to Red and a bit to blue and OIII to Green and Blue.
