Comet with naked eye coma ZTF - 25.1.2023 at 01.00 - 25.1.2023 at 02.30 Fregenal de la Sierra, Espanja Observation number 111549

Visibility IV / V

Tapio Lahtinen, Tampereen Ursa

I got nervous about the cloudiness in Finland and then I got nervous about the cloudiness in Italy (I tried to describe the SkyGems tube there). In the end, I ended up buying shooting time in Spain with a larger camera.
You couldn't choose a shooting time there, but luckily the second possible night was clear and my order fit into the shooting schedule.

Here, as a quick processing, only a 30x40 second exposure.
My machine crashed when I tried to process all 90 images.
Well, let's try again...
Edit: Another processing attempt and this time with the Siril program. A little strange logic, but I managed to get all 90 pictures processed.
