Hi,

I would like my stars to look better, lot's of them have blue halos around them, I would also like to shrink them a little bit.

Here is a link to a file with stars only: https://www.dropbox.com/s/hx0sl3g7xj6v46n/Stars.tif?dl=0

Any ideas what could I try please ?

EDIT:
I have managed to create a mask with GAME script for the star with huge blue halo (top right part of the image), but have no idea what to do next.

Thanks !

I have tried Erosion on them but it only slightly reduces them and they become blurry.

I wonder if there is PixelMath algorithm for blue
halos, I have seen one for red halos.
