Details:
As of Wednesday night comet C/2023 A3 (Tsuchinshan-ATLAS) became invisible to my 7x35 binoculars. My 15x50IS binoculars could still spot it--including a 1° tail--as an easy averted-image object; in the photo it's almost 2°. But with predicted cloudy conditions for the next few days, the night probably marks the last time I'll see it visually in some way. I never did see it naked-eye despite a couple sessions spent in dark-sky locations. It's a strange comet: rather attractive in form but dimmer than expected and with unusually low contrast.
It's all the same photo, seen as:
#1: closeup
#2: unlabeled
#3: labeled
