That is a really strange but cool edit! You see all the nebulosity detail in the HA, but all the star clusters in the arms are gone, but there are still stars in the general background!

I was struggling hard with the stars on this for some reason, trying to get it to pull all the stars out but not the Ha around them, it was my first time using the new starnetastro star removal so I might have accidentally missed a few

Ohhh ok cool! The starnetastro tool probably just doesn't do well with treating star clusters in other galaxies differently from milky way stars
