    Separating selection from action that works on the whole image

      Hi everyone, my first post on here, still finding my feet with PS.

       

      I have the Noel Carboni Astronomy Tools Action Set, I am trying to remove the purple halos around stars in an image of the Large Magellanic Cloud, however when I use the tool it removes a lot of the colour in the nebulosity of the (dwarf) galaxy (I also used Defringe in Lightroom which had the same effect).

       

      I have tried to select the galaxy with the lasso tool and invert the selection and then run the action, however it applies the action to everything still.

       

      I wonder is there a simple way to separate out the galaxy, run the action and then put the galaxy back in? Can it be done using a mask and then blended back in? If so I'm not quite sure how to do this.

       

      Thanks in advance.
