This is the next step of the process.
The way of dealing with these issues collectively (including sky glow) is to normalize the sky background of the stacked OIII and Ha images before constructing the masks.

The masks are applied to the OIIIHaRGB image and enhancement is done through the masks exclusively with the R channel.

When I get the time I'll process and post the final result.
