Comets
Despite some cirrus clouds passing over the sky I could create this composite of comet Neowise. It shows the travel distance of the comet during a time of 20 minutes. Reprocessed 2024 using PixInsight: Stack and alignment of 50 pictures (plus dark, flat, bias) and tracking on comet core. Postprocessing with Photoshop. ISO 800, 20 seconds exposure time, interval 25 seconds. Nikon D850 with Nikkor 300mm 2.8D at f/2.8. 19 July 2020, Bözberg.
Shot on 13 October 2024 near Cheisacher Observatory in Aargau. Unfortunately the comet drowned in the cirrus clouds afterwards. I could have used 1s exposure time without star trails. — EXIF: Nikon D850; Δt=1/2 s; f=300 mm; f/2.8; ISO 3200; 2024-10-13 19:44:36

Shot on 14 October 2024 near Cheisacher Observatory in Aargau. Comet C/2023 A3 Tsuchinshan-ATLAS was mostly behind clouds. One can see trails of those bloody Elon Musk Starlink satellites.
