Isolated patch of colourful high cirrus when all around is a washed-out grey ~ a foreground star possibly responsible for the illuminations


This is a controversial object. If you look it up in SiMBAD, it says it’s a hot subdwarf (which obsiously is associated with.) there is a note regarding this as “Not a PN according to Frew et al. 2013 (2013MNRAS.431…2F)” but is regarded as a true PN in HASH and CEND, but not in KEN. It did end up in several PN references about this object.
