    2 galaxies also!

    Galaxy UGC7652 Magnitude 16.5

    Galaxy Mac 1230+1221 magnitude ?

    An energetic jet from the core of giant elliptical
    galaxy M87 stretches outward for 5,000 light-years.
    Ultimately, the jet is thought to be produced as matter
    near the center of M87 swirls toward a spinning,
    supermassive black hole.
    Strong electromagnetic forces are generated and eject
    material away from the black hole along the axis of
    rotation in a narrow jet.

    ouch, ouch. Thanks to Jan Damhof who reminded me that the jet is coming from another site of M87. So it's not the jet but an artifact I am afraid......

    I did another stack again and heavier leveling and the results are amazing. Can see the 'old wrong' jet but the new one also.
