    Description

    This is a first reprocessing of an old image, that you can see back in my gallery.
    Not really satisfied, though. Maybe I must restart from scratch...

    Update #1:
    in this new version I tried to improve the overall aspect, based on the feedbacks received.
    So, I tamed the reddish cast of the bulge, reduced the halos around the brightest stars and reshaped the bright stars.
    Hope you like it.
    Ciao

    Update #2:
    as per Frédéric Tapissier comment, I did some retouches to some stars in the picture, expecially those superimposed to the galaxy. Thanks Frédéric!
