For those who saw my image of the
Fighting Dragons of Ara and the discussion that followed about the small 'lemon shaped' nebula to the bottom left of the image and close to the planetary nebula Henize2-169, here is the (??first amateur astrophotography) colour image of PCG11 and I decided to settle on The Jaws Nebula for the name. There is pretty much only Ha in this region but the "Jaws" do stand out nicely from the background as does the small planetary nebula Hemize 2-169.
PGC11 is a wind blown bubble created from the stellar wind of a central Wolf_Rayet star. "Scalloping appears around the whole interior of PCG 11 in gas that is a combination of swept-up ISM and stellar ejecta. This is sandwiched between shocked ambient gas and an inner contact discontinuity at the interface with the stellar wind" (ref A new Wolf-Rayet star and its ring nebula: PCG 11, Martin Cohen, Quentin A. Parker, Anne J. Green).
The image is composed of 15.5 hrs of Ha and 4.5 hrs of RGB plus some short exposure for RGB stars.
Unfortunately both targets are very small in my the FOV of my 10" Meade SCT with the focal reducer in the imaging train.
If I evert win Lotto, I might then be able to image this target with something like a CDK24 or better but until then, this image will have to do.
This is a cropped version to highlight the scalloped features of PCG11
