    Darkened the background just a tad...

    C

    Complete redo... I got rid of the over sharpened dust lanes in the core and improved the background. The faint fuzzy galaxies are much better now and done without any noise reduction to the background!

    D

    Softened up the Ha regions.. they were too glaringly bright...
