    Congrats on your APOTY Highly Commended Steve! I am glad the judges saw the due merit clearly displayed in this image, they could have easily overlooked it for the more "spectacular" images.

    Thanks Mike and Brendan. I guess that one of the things that may have impressed the judges is the faintness of this planetary. It's only magnitude 12.6 and almost invisible visually unless you use an O III filter (at least to my imperfect eyes).
