M106 with bonus galaxies (reprocessed)

After watching a few more hours of PS tutorials, I decided to reprocess the M106 image. In an attempt to reduce the red in the image, I decided to more aggressively black clip the Ha data, prior to blending with the PS screen mode. To improve the image quality, I also used noise reduction on the Ha data.  I then made a few slight changes to the colour - to reduce the red further I change the Hue slightly towards Blue. To increase the effect of the Ha regions, I reduced the amount of cyan. Finally, I decided to apply a PS cooling filter - totally non-scientific but I thought it improved the image. I also took the opportunity to correct a few star defects: non circular stars, where fixed by a radial blur and a few red star halos I'd missed from my previous attempt where eliminated.
