NGC6888 Crescent

Another picture shot at poor skies. I've got too prominent stars, even if they are reduced, and I'm not sure why this happens. At Astrobin I've seen similar images with dslr and their stars are dimmer with more visible nebula structures. May be it is because my poor sky?

I think I've overprocessed it a little bit.

And I've done the tutorial about separating stars from nebula. I've diminished a little bit the stars bright

Hi Alvaro,

That's a very respectable image nonetheless. In order to tame busy star fields, you can use the Magic module (using the Shrink or Tame algorithms, where Tame is best used on stars with overexposed cores), or (my favourite) the Isolate preset in the Life module (with full mask).

Thanks for the advice Ivo, I didn't remember about Tame method. Stars are already shrinked 1 pixel with Magic module and nebula has been also isolated. The problem (if it is a problem) holds in my stacked fit file.
