Description

Seems the only previous image of this on Astrobin is by Gary Imm.

Gary commented on the "U" shaped outer ring.  Mine looks a little different and I checked that the lighter area may reflect the additional H-alpha.. where you have both H-Alpha and O-III the image looks whiter/brighter.  It still is mostly O-III, which looks a bit like a corona of some sort when blown up (High magnification/rescaled so to speak). This may be what is referred to as a weak eliptical ring in the write up from Deep Sky Corner below.

Nice write-up from Deep Sky Corner.... their image gives you an idea of how dim this really is.
