spectroscopic and comet observations on 9 jan. 2025

a cold day, we had a clear sky here with some disturbing moon, I was able to start with spectroscopic observations of Be stars: gam Cas, HD224544 and PZ Gem (not observed), unfortunately the latter was interrupted by clouds that kept drifting in. I was also able to observe some comets after a series of technical problems: 333P, C/2021 S3 and C/2024 J2.
