Comet C/2023 A3 Tsuchinshan-ATLAS
21 x 30-sec exposures at f/4 and ISO 3200 with an astro-modified 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 software, and the result post-processed to increase contrast and to reduce noise and colour gradients caused by light pollution. I also used Starnet++ to temporarily remove the stars (which otherwise dominate after stretching the contrast).
