Shooting w/different line filters make for interesting pics on their own as well as a supplement to the RGB data.

    When your finished w/stacking an Ha image this is what you'll see after an initial stretch (your raws will look similar)-top pic.
    At this point you'll want to extract the red channel and get rid of the green and blue channels(very little "good" signal mostly noise) and convert to grayscale-bot pic
