C/2023 A3 (Tsuchinshan-ATLAS) at the VCO October 22 2024
Another clear night, perhaps one of the better ones since the 12th. It was the first time I was able to observe the comet really well with 8x42 binoculars. This time I imaged at 200mm with a tracker for 351 frames. This provided a more detailed view of the head.
