Hi Marc,
Super effort. 16 hours is bigtime serious imaging effort. Nice round stars
and lots of things done really well.
There is plenty of red in the image. Its all in the processing
in how to bring it out. You don't need more S11 etc its already there
overwhelmed by the strong Ha signal which of course as Ha is assigned
to the green channel easily becomes overly green.
We are used to seeing a balance of red green and blue in an image
so when one colour is dominant it isn't an ideal effect. Whilst you can
make it what you like in narrowband I think the images that get the
compliments have a nice balance of RGB going. There can be some really
nice mustard colours in narrowband as well as some lovely blues. That in
my opinion is where the beauty is on a nicely done narrowband image.
Martin Pugh's running chicken nebula image of last year is a good example.
So are ken Crawford's narrowband images. He is one of the very best.
I can email you (or post a link here) a version I reprocessed to show a more balanced RGB with
various tweaks.
How you handle the red stars is up to you but there are a few choices that I am aware of:
1. Shoot shorter RGB for the stars and use tricky Photoshop layers techniques to replace the red ones.
2. Use techniques to minimise the stars (not the minimum filter although in mild use it might be OK).
3. Use Photoshop tools to select out the stars and work on the colours
using standard photoshop tools.
Its worth learning a few more Photoshop techniques as 16 hours worth of capture time means its worth it.
