How much is artifact, and how much is real???

compare #artifact and brown matter around it on the big star to spokes of brown matter radiating from an ancient bubble off the upper right corner. Note also the distribution of #darknebula around the #bigstar and the features that might be more than artifacts of the photo process. How much do we know about this #bigstar? What is the scrap of green ray at 11 o'clock about? What is the fuzziness at 5 o'clock?
How much is artifact and how much is legitimate object, and how can we tell?Posted

The GLIMPSE viewer on Alien Earths suggests what I am tagging #bigstar is a planetary nebula #planetarynebula , but it hasn't helped on the green rays yet. It does seem that calling these #artefact or #artifact is a misnomer.
