Description

This image of M 101 was captured in April before the supernova exploded into being. I used Ron Brecher's Pixel Math (Masters of Pixinsight) formula to combine the Ha with the LRGB. I'm pleased with the results. You can control the amount and intensity of the Ha - making it very useful. I also used Russel Croman's Color Coordinated HDRMT and liked the the way it preserved color. I see on the Pixinsight Forum that they are going to add that to the standard HDRMT in Pixinxight.
