I captured an image of comet Tsuchinshan ATLAS using a Rokinon 135mm prime lens at f/2.8, mounted on a Canon 1300D DSLR camera, which was attached to a Star Adventurer 2i pro tracking mount. The settings were 15 seconds and ISO 1600. I took 15 images and 35 flat frames, all stacked in DeepSkyStacker and processed in Siril, then finished in PhotoScape X. Additionally, I used a 10-second timer on the camera and a Bahtinov mask to focus on a bright star. The image was captured under Bortle 3 skies at Rosehill Gower.
