      Description

      Another exceedingly faint target (all my fault!), this time a supernova remnant in the constellation of Cassiopeia. This is my first HOORGB processed image and I'd like to thank Rick Stevenson and a PI forum thread for pointers in how to combine the RGB stars using PixelMath, worked a treat. There was still plenty of processing required afterwards though . . .

      Time for us to choose a bright target!
