Comet Nishimura & Eskimo Nebula (right end)


One week after its discovery on August 12, 2023, I captured Comet 2023P1 Nishimura in the eastern lower sky at dawn. It was positioned approximately 7.5 degrees SSW of Pollux in Gemini. I could observe a comet with a 9th magnitude bluish-green coma and an extremely faint tail extending to the west. On this day, a degree west of the comet, the planetary nebula NGC 2392 (Eskimo Nebula) was also located.
