The stars post process is nearly useless, it was just an experiment and 
never really intended to be used in a real scene. Post processes would 
be extremely limited when it comes to stars anyway.(reflection, 
transparent objects, fog, sky_spheres, etc....)
I suppose it could be useful for creating an image_map to use on a 
sky_sphere...but that is about all. I will put this on the list of 
things to fix, though...

However, your problems with the stars overwriting the earth sound 
strange...the filter I released should only overwrite "infinite" areas, 
which don't hit anything nearer than Max_Distance. How far away is your 
Earth?
