Hi Franco,
yes high K values will give White stars -
those bright stars have most likely exceeded the well depth
of your CCD pixels which means that all information is lost.
Only a short exposure will remedy that.
It's easy and quick to do on any target -
just 1 frame each of RGB for say 30 seconds.
In Photoshop -
select color range
highlights
modify
expand by say say 2 pixels
feather by say 2 pixels
copy and paste the stars on to the main picture.
Suddenly the center of all stars have color.
cheers
