Comet 12P/Pons-Brooks - 5 March 2024
Thought I'd take the opportunity to capture the comet, currently in Andromeda, again. The sky was less murky than last night, but it's likely to be the last clear night for a while.
22 x 30-sec exposures at f/4 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. Also Starnet++ software used to temporarily separate the stars and comet and prevent the stars bloating when comet contrast is stretched; this has revealed more of the tail that would otherwise be lost in the star background.
