To all, "the center is not in the middle," amazing what I can say during a sleep deprived night of great observing! It was, and still is, a great night with my old 8" Newtonian.

True, the core seems to be off to one side. A strange shape indeed. And 4631 is truly massive and very mottled. Lots of fun.
