Dust Donut Removal Technique

Alan Karty
in PixInsight
Hello Adam.

Regarding the subject technique, is it sufficient to just remove the dust donut from the luminance or must I also remove it from the R/G/B images?

Thank you.

    Hi Alan,

    It is probably more important to remove it from the luminance- since the donut is likely in the sky, which are dark pixel values. Any color that is dark will be hard to see... and if you neutralized your background color... this will further minimize the issue. So... luminance is more important.

    p.s. Everything depends... depends on how bad it is in the color data. :)
