This comet was quite bright, just about naked eye visible in better conditions, but was rather low in a partly cloudy sky.
Astro-modded EOS 600D,Carl Zeiss Jena 135mm f/3.5 Sonnar M42 Just 11 x 30-sec exposures at ISO 3200 and f/4, stacked on the comet in Deep Sky Stacker software (hence the slightly trailed stars).
Result post-processed to reduce noise and increase contrast, though the small number of frames has resulted in a still quite noisy image. The image was cropped to about 70%.
