This is a very cool, although slightly time-consuming method for controlling noise in your astro-photos. I use luminosity masks and Topaz DeNoise to reduce noise cleanly, but this seems to do an excellent job too. It involves stacking multiple images and using the Median function. Thank you to Ian Norman for the tutorial.
