Here's a file RAR file here with a stack in PS based on your original picture.
I isolated the two layers of interest, one for the neb and on for the stars. Have a look at the settings. You'll get the gist of things.
In the end it all comes down to proper star masks and how much time you want to spend on it. Mask are easily done but using a difference blend between layers then refine the selection by contracting/expanding then feathering.
Also keep in mind the shadow highlight tool on stars only. It's a flexible way of deringing your stars while controling the cores and colors.
Finally blending layers on top of each other as "color", "lighter color", "Luminosity" helps as well getting rid of hard edges. |
I've downloaded it but not yet had a look at it Marc, hopefully find some time tonight
I've done
Version G now. Tried adding some more red but I don't yet have the time to try to mask all of those minuscule red stars embedded in the nebulosity. That may be a job for the coming days.
Version F was an attempt to replace the stars using the techinque Rick suggested, using the CIEa&b, works well but there is visible issues due to star masks
It wasn't so obvious in the 32-bit format in PI.
Version G was just keeping the original stars but making them look nicer, think I prefer the Hubble stars moreso.
