This is the 100th planetary nebula I have processed! Woo hoo. Lots of strange and interesting structures in this one. The dust lane looks like it's corkscrew-shaped but I might be imagining that.
I used some WFC3/UVIS data for the nebula itself and some older WF/PC to finish off the corners to expand the star field so the composition wasn't so closely cramped around the nebula.
