Visibility II / V
C / 2016 VZ18 is the discovery of PANSTARRS 1 (FISH FISH) from last fall. Ville stacked the comet and left a few observations in the middle to make room for the comet, the star string :). This technique was invented when measuring the brightness of a comet. Kari stacked according to the stars, from which you can see the movement of the comet in 20 min. The comet is perhaps at its brightest right now.
