This comet has a roughly 6-year orbit; I last photographed it in 2017, though it's better placed and much brighter this time round. It's currently in Leo.
Modified Canon EOS 600D,Revelation 300mm f/4 Newtonian 20 x 1-min exposures at ISO 3200, stacked on the comet in Deep Sky Stacker software (hence the trailed stars).
Post-processed to reduce noise, increase contrast and reduce colour gradients caused by light pollution.
I also cropped the image heavily this time, as the stacked exposures with different framing gave me untidy edges.
