    Oh that is odd. If you go into examine you can see it's near the edge of the SDSS survey (zoom out a bit on Sky server)

    So I wonder if there is only a good green (r-band) image there - hence the odd green look.

    In fact if you keep going through to NED (NASA Extragalactic Database) you can see it is a #planetarynebula cool!

    So it's could really be green because of the strong emission lines which fall in the r-band filter of SDSS.

    A luminous doughnut!
    If it's an SDSS image it's presumably just gone through the green filter? Like one end of an asteroid?

    Very strange spiral galaxy with ring instead of bulge inside.
