Abell 82 (also catalogued as PK114-4.1) is a small and faint planetary nebula in Cassiopeia constellation: It has magnitude 15.20 and apparent dimension 94”.
Its structure shows a bipolar morphology, with a bright centrale zone and very faint polar lobes.
The image is an RGB reinforced with Ha and OIII contributions: I've done a small crop of the original frame due to very small dimensions of the nebula.
