local convolution/smudge

[aworonow]

Frequently, I find small blemishes in my nearly-completed images. Most recently when doing some narrow-band processing, the dozen brightest stars had color hot-spots a few pixels wide in there centers. It would be very convenient to have a tool akin to the "smudge" tool of Gimp to smooth those out, or an adjustable circle that, with a click, applies a convolution to its selected area.
I know this may raise concerns about "painting" the picture, but the need is real and not altering data, just artifacts.

Make a mask with RangeSelection to pick up the bright stars, clean up a little if needed, apply & blur (e.g Convolution, MMT to Chrominance if you only want to blur the colour.)  No special tool needed

Cheers,

Did just that with convolution through star mask, but not to just chrominance. Will try that...thanks
