I am very new to Gimp but this is what i did, hope it is ok Alex.
1st i opened the image in gimp
then tools > selection tools > select by colour
In select by colour i had threshhold set to 45
Then clicked on one of the stars
then select > grow set to 2 then select> feather set to 2 also
then > filters > distorts > Value propagate and change the mode to 'more black'
and that's about it mate.
you can play around with threshhold and grow, feather values
