    What the heck is that green ring??

    I ... have no idea. I think someone with a bit of expertise should have a look at that. Very interesting! Nova remnant?

    Hi farrelly and maclypse and welcome to the Zoo

    The green ring is an optical artifact, no idea what causes it though !

    Happy hunting ! 😄
