Description

I think an Astrobin first.  This is a Planetary nebulae that cannot be explained by binary systems.  It "may" be a triple system. 

I looked for O-III in 3h of subs and found none.  There are few good photos (Here is really the only I found and it is very nice, but not O-III and is 38h of 5nm H-alpha):
