Veli-Pekka Hentunen, Warkauden Kassiopeia
I photographed comet C/2022 E3 (ZTF) early on Monday morning 2 January 2023 at 06 - 06:40 with the Härkämäki observatory's C-14 telescope and SBIG ST-8XME CCD camera. The weather was clear, minus -5 C. Two tails are clearly visible on the comet, of which the longer and narrower gas tail continues outside the picture and is probably almost half a degree long. The dust tail is quite wide, fan-shaped.
