How do i pull out Nebula Colors?

[vast aurora]

I am processing a RAW Stacked of someone who produced a great image of heart and soul Nebula, so i know the Raw has the stuff in it, but i wanted to pratice processing. Well, I cant get any red color from the nebula to show at all..

You’ll want to try a photometric color calibration, if the uploader didn’t do it for you you’ll have to platesolve first

Can you explain? I am beginner in astrophotography.. I have photoshop experience but more of the creative design and less on photography.

this is what i have after some curves and levels.

this is the owners final processing image. I have no clue where the red came from

No shot. I try that and it blows up
