Re: [guide-user] planetary nebula very near Albireo unfound in Guide

Hi Patrick,
Errrmm... didn't see any planetary nebula image; can you elaborate?
Are you sure there's a planetary there, rather than an image flaw?
Its absence in any database is somewhat suspicious. (New planetaries
_are_ getting discovered, but I think we're at the point where they
look essentially stellar; spectroscopy is required to ID them as actual
planetary nebulae.)
