I did a quick processing of my 2021 narrowband version of IC2177 - Seagull Nebula using a color palette developed by Dylan O’Donnell. This palette was developed to mimic natural color rather than the psychedelic color scheme of SHO images. Basically Ha is put into the red channel, OIII is put into the blue channel, and broadband green is used for the green channel. Dylan was asking for examples using his technique. Ideally I would have collected more green but it is what I had. It certainly looks closer to a natural color scheme. Since I was able to do a real RGB image, I was able compare the star colors with the HaGO image. To me it looks like they match pretty well.
