62P/Tsuchinshan 2023-Dec-09 Dan Bartlett

For December 9th:
Another fantastically transparent and stable night to image 62P/Tsuchinshan. Even better than the 5th, where the 3Q moon was a mere 20 degrees away from the comet (seehttps://astrob.in/rlnda3/B/), this time the skies were without moonlight.
