Comet Wirtanen photographed from E-eye's sky on December 9, 2018.
So nimble guy that 60s exposures made a line so I ended up with 30s exposures.

1. The image is aligned with the comet itself

2. This was treated as a Larson-Sekan filter, with the idea that the tail could be excavated, i.e. with the same technique as the other graphs in the Sky Guard. I used this for the first time. I had to learn and I don't know how I succeeded in that, but yes there is at least a little tail in the picture and maybe another tail, which e.g. Tapio Lahtinen's picture is quite clear
