You’ve resolved it well Plus, globular are very red
One suggestion I would make when photographing any star cluster is not to use a light pollution filter as it can make colour calibration difficult and light pollution doesn’t affect them so much
I prefer your first one. I do agree with Leon, it lacks a bit of contrast, but nonetheless it's a very good image. As it says beside my name, I like Globs!
Hi Fernando
Nice image of Omega
Well done
I’ll second the advice about filters , you don’t need them for globs
Try again without the filter , I’m sure your image will be cleaner with more definition and some colour in your star field
