Composite of 4 min, 2min, 1min, 30sec, 15sec, and 7 sec exposures, each exposure being a stack of 3 to 4 identical exposures. Registered and stacked in Photoshop (HDR mode did not produce usable result, so manually composited with sucessively smaller masks to reveal short exposure content around nucleus. Contrast exaggerated with Curves to bring out very faint tail structure. North up, so tail to the S and SW.Nucleus is dot at upper left of inner coma, other star in inner coma at right is a field star
