Details:
Taken just after midnight (MDT) on 19 July using Nikon d7100, Nikkor 180mm f/2.8 @ f/5, iso 1100, 13x150s.
Sky transparency was excellent.
Since comet was moving pretty fast and parallel with the stars, I used PixInsight to filter out the stars to show a stationary comet. However, since the comet was ~9th magniture, I couldn't eliminate all the fainter stars without negatively impacting the quality of the comet.
