I know tastes are in nature, but I thought I produced a nice bubble but that's my opinion. My goal right now is to move to a second level and for that I need your valuable advice. Go ahead without holding back, I really want to move on to another stage and right now I think I'm my own drag.
Bubble Nebula - NGC7635 in HOO + RGB STARS
Thanks

I think this is a really excellent image. Great stars, great detail and the 3-D appearance we all try to achieve with this subject.

Martin,
Usually the bubble shows a lot of color variation with blues, golds, reds, and yellows. Depends on the mix you choose of course. If there was something to add to your image, for me, it would be color differentiating the structures.
Cheers,
Kevin

Thank you Kevin, as soon as I have completed the acquisition of the SII layer, I will be able to add a little more color to it. Is it possible to do this with only the HA and OIII layer?

Yes, I think an HOO will give you most of the reds and blues. Adding the SII will then give more color definition.

For color with just the Ha and the Oiii, you might try this in pixelmath---
R/K: HA
G: (HA*OIII)*1.5
B: OIII
Then apply background neutralization and it can look pretty good sometimes.
This is the Steve Cannistra synthetic green method that I have played with. I found this on the Light Vortex Astronomy website in one of their excellent tutorials.

I found this excellent tutorial that explains how to enhance blue color in NB images:

You might try to follow it if you want to highlight the blue part of the bubble.

This way you will get a yellowish color on all the Halpha regions.
If you want to keep the red and enhance the cyan on OIII, you can use the Linear Fit process: use OIII as Reference and apply on the Halpha, then process as you did here.
