Comet C/2023 A3 Tsuchinshan-ATLAS through patchy cloud, 21 October 2024

Taken on the first of 3 evenings imaging the comet, though the weather was never quite ideal. On this night patchy cloud caused the uneven background in the image.

18 x 30-sec exposures at f/4.5 and ISO 3200 with an EOS 600D and Zeiss Jena 135mm f/3.5 lens on a Vixen Polarie star tracker. The frames were stacked on the comet in DeepSkyStacker, hence the trailed stars. Curves adjustment and further noise reduction were applied in post-processing.
