Even the single 120 second subs showed more of the "tail" than  I have witnessed to date.  I even think I'm seeing a "bowing" of the anti-sun tail away from the direction of cometary travel.  There also seems to be a slight eccentricity to the coma, shortened on the forward directed side.  All could be my imagination, your guess is as good as mine.

I've included the 85 stacked frames of comet "only" full scale image, which initiall made my jaw dropped when fist view on the computer screen once the integration routine completed.
