Comet with naked eye coma ZTF - 30.1.2023 at 04.13 - 30.1.2023 at 04.35 Fregenal de la Sierra, Espanja Observation number 111775

Visibility I / V

Tapio Lahtinen, Tampereen Ursa

The intention was to film a longer 3-hour session following the comet, but the Meridian flip failed for some reason and photons were only collected for less than half an hour.

Secondly, since some people also photograph galaxies with narrowband filters, I decided that why not comets as well. Well, the result is not very surprising.

Edit: added a small animation
