Stack of 4 images (processed with Affinity Photo) with median value. Adjustments: Curves adjustment, high pass filter (sharpening) for some stars, denoising (not on the comet or stars), crop.

Using a tripod, this photo composite was taken from the rooftop of an apartment building in Cardiff, Wales, UK. We waited about 1.5 hours after sunset and saw the comet just underneath the big dipper. Just after the photo was taken, the clouds rolled in - it was a lucky break!
