Photo description / processing

Calibration: Darks, Offsets, Flats, 31 frames each January 23, 2020 I managed to photograph the comet between the clouds on January 23rd. To capture as many frames as possible, I shot at 30-second exposures, even though both the stars and the comet allowed for longer exposures.
