Thanks for this plugin. I'm using it to try and remove the colour shift caused by my light pollution filter on an unmodded Canon 350D. Everything has a cyan hue to it. Haven't had chance to try on a G2V star yet but I have located a suitable one so will give it a go. Been struggling with this for some time now so I'm hoping this is the solution. Incidentally, this works fine on Photoshop CS5/Windows 7(32) for me.
Cheers

This plug-in sounds like just what I need. I have a detailed image of the Rosette but my Custm WB didn't work and it has an overall reddish cast. I'm a little unclear on the selection part. Basically I have stars, nebula and background and a lot of the stars are in the nebula. I tried selecting a small area of stars and that didn't work out well, then I selected just one star and a little bit of the halo and that seemed to be better. Could you maybe elaborate a ltttle on what I should select? thanks, Al

Al, just select an area that you want to assume it's of neutral color. This is your decision. The simplest way, if you want a specific recipe, would be to select an unoccupied area of the background.

I really like this plugin, but I wanted to know if it was possible to have a similar plugin that will also adjust the exposure so the selected area is remapped to a mid grey (RBG value of 0,18 in 32bits). That would be really handy for calibrating pictures taken with a macbeth chart. Your plugin already does the biggest part, I would gladly help to modify, if you want.
Thanks!
