A very nice Helix there Adam. I think though some noise control is needed as there is some red noise in the blue areas and the outer edges seem to have broken down and pixelated.

So the background is too dark and this is black clipping the outer edges of the Ha areas and a bit of the Ha red has sneaked through into the blue O3 areas. I would mask the Ha out of the inner blue region as there should be no Ha there.

Greg.
