Does it matter that when using the erosion to remove the stars that there ends up being ringing artefacts caused by the star mask itself? It erodes the area around the stars, not just the stars. I can assume that when the stars are eventually put back in that it covers over these areas again. Or does this mean I just have to make a better star mask
Just been having a play, I can remove all but the smallest of stars but there is some residual star mask ringing. This does not to be as big of an issue when removing them but it definitely is when trying to put them back
So, more tweaking and learning in star masking me thinks
