One quick one from tonight’s trip up to the closure point of Guanella Pass at 10,800′ MSL. Pretty dark and cold up there, and for some reason the image looks quite a bit different than last night’s. The tail seemed a bit less obvious, however I was able to capture more detail in it (note the two dark streamers coming out from the coma). The comet was naked-eye visible with off-center viewing, looked as bright as through binoculars in Golden last night.
