Comet 13P Olbers
The comet is still low in the twilight in the constellation Lynx, but this image, while still rather noisy, is an improvement on what I captured in June.
16 x 30-sec exposures at f/4.5 and ISO 3200 with an EOS 600D and Zeiss Jena 135mm f/3.5 lens on a Vixen Polarie star tracker. The frames were stacked on the comet in DeepSkyStacker, with curves adjustment and further noise reduction in post-processing. The image was also heavily cropped.
