Description

When processing my photograph of the Spider Nebula (https://www.astrobin.com/yt8gm4/) I experimented with finding a good luminance image. The max(R,G,B,O,H) formula in PixelMath produced a beautiful B&W image, but too contrasty. The effect of adding color was not good. However, when adding the color stars to the B&W image, the result seemed very striking to me and that is why I share the experience.
