At my location the mountains to the west rise up to about 12° above the horizon. There was a fairly narrow time window, about 20 minutes, between the end of Nautical Twilight and when the comet set behind the Bristol-Head mountain ridge.

Photo-bombed by satellites! Not much time for a do-over, the comet is about to slip behind the ridgeline:

The comet's tail seems to extend about 2° in these short exposures.
