Everyone knows I love PN's probably because my OSC cameras work well with Ha/OIII filters.   I have seen the occasional image of this object but they are few and far between so I jumped at the chance to process this from Mike Selby. 
The Flaming Skull, not the worst nickname, ( as in Rotten Fish Nebula)  or see @Gary Imm 's list here: https://www.astrobin.com/396279/
... anyway the SH2-68 is located mostly in the south near the constellation Serpens, and is thought to be one of the oldest Planetary Nebula's.
