looks like a planetary nebula with spiral arms, odd.

If it's real it's very weird, but it could be an image mismatch between bands, which is why it only shows up in bright green. Skyserver is having some trouble with the coordinates.

Ah, klmasters (Karen from the science team) just pointed out it's right on the edge of the survey, so probably just not observed in all bands. But it is a #planetarynebula.

Brooke (etc) I got confused by talk and responded as a comment in the image, not the discussion. It really does seem to be a #planetarynebula (go through to NED)

SDSS reports it's ~2 mags brighter in r than any other band, so agreed, if it was observed in all the bands it's this bright green in the image because of line emission.
