Astrophoto: Comet Tsuchinshan-ATLAS – C/2023 A3 – 10/24

The Comet is a long-period comet from the Oort cloud that was discovered in early 2023 and made its closest approach to the Sun on September 27.

I used my chance when there was only a very short period without clouds. It was windy, it was not really dark, guiding was a mess … I am still happy.

Session Planning

The most important informations when planning a comet session – beside the weather – are camera rotation and finding a good center object.

Session Analysis

The session was a mess – when I compare it to a deep sky session.
The focus was ok, at least the later one when the clouds were gone. I do not want to comment the guiding.
