Following the night prior (https://astrob.in/5019c7/B/) ,where comet 13P/ Olbers "feathered" off into fine filaments of plasma streamers, this night showed the comet rotating its most active region upward. This image may have caught the plasma tail rising from it's lower position to its upper (less favorable for target framing) leaving remnant of past lower tail activity. The broad dust fantail is still very dominant. Sadly, the seeing conditions were not favorable, thereby losing some detail, whereas the transparency was favorable. I'm excited to finish processing the widefield setup since the initial precursory overview shows more tail activity.
