Stars coloring

Hi,

Is there a way to colorize stars that are near saturated in the center?

I can do it one by one, by adding a smoothed mask, and then for a red star, decrease the green and blue channels.
But for a star rich field, this can be tedious work. Is it possible to automate this with Astroart? Is there a function, that I have overlooked?

A "Colorize Stars" feature would be great, I recon that Astroart could use FWHM for each star, to detect the non saturated color near the edges, and enhance that towards the center?

Maybe the fastest way is the Brush tool of the Mask Window, using "Add" mode.

So, just do a single click on every star of the same color, then you may color-correct all stars with a single processing. Does this helps?

Thanks for the prompt reply Fabio.
Well - yes, that’s actually how I do now. But it is difficult to find an adjustment, that fits well for more than one star. Also, for example with M13, you quickly wear up the mouse button ;-)

I have put together some C# code, I hope You can read it. I will send you a link to the project, source code and all.
