Nice night for a comet with a very slow apparent motion.  I only used 10 x 300sec exposures for this busy field, with little to no pseudo nuclear trailing at this pixel scale.  Full resolution on ASTROBIN https://www.astrobin.com/8wr3pm/(typo of comet designation will be fixed when ASTROBI is fixed)
