Comet C/2023 H2 Lemmon

As with Nishimura in September, I used a telephoto lens on a star tracker rather than a ‘scope because the comet was poorly located for me in the sky. It was actually quite easily visible in 7 x 50 binoculars.

Modified Canon EOS 600D,Carl Zeiss Jena 135mm f/3.5 Sonnar M42
12 x 30-sec exposures at f/4 and ISO 6400; camera mounted on a Vixen Polarie star tracker;
frames stacked on the comet (hence the trailed stars) in DeepSkyStacker, with curves adjustment, further noise reduction and some cropping in post-processing. hide exif
