Comet with naked eye coma ZTF - 29.1.2023 at 02.30 - 29.1.2023 at 06.06 Uurainen Observation number 111763

Visibility III / V

Aleksi Ruotsila, Jyväskylän Sirius

Sacrificing a reasonable sleep pattern and a night's sleep, I left early in the morning to photograph this comet when I had the chance (weekend, moon setting, a suitable opening in the clouds). The comet's tail was a fairly steadily moving jet during this viewing interval, while a couple of days ago when I was photographing it there was much more life. Undeniably an interesting and dynamic object to photograph. For the comet, almost 3 hours of exposure, and for the stars I used the same photos from just an hour ago.
