I have been patiently waiting for Comet C/2023 A3 Tsuchinshan-ATLAS to get into a dark part of the sky, with no moon, to perform longer integration imaging.
I was finally able to use a telescope with longer integrations, to capture a high-resolution image of comet C/2023 A3 Tsuchinshan-ATLAS
You can see a "hood" (or hoods) in front of the nucleus, as well as some details in the tail.
