    M106 in Canes Venatici. Listed at aprox. 25mil Light Years distant - so about the same distance as M51. Listed as a Seyfert II "active" galaxy. The Ha signature I think shows this with the streamer coming of the core (red in the main image). Ha mixed into the red channel at 30%. Seeing was pretty rough, so anything beyond subtle sharpening attempts proved futile.

    Original image = Ha raw data
    Image B = LHaRGB

    L = 51 x 300 1x1
    Ha = 13 x 1200 1x1
    R,G,B 15 x300 each (total 45) 2x2
