Description

This is the n.85 in Abell Catalog of Potential PNs but isn't a PN at all but a much rarer SNR. Initially I went for the L-ENH but quickly figured out that it wouldn't cut mustard with this beast (misleading indications of its true size in all catalogs I've checked), and quickly bought a L-EXT for the specific purpose of chasing down all the members of the Abell PN Catalog north of the equator not yet under my belt.
