Comet and spectroscopic observations on 4 febr. 2025

the weather reports did not bode well, it was still clear in the early evening with light veil clouds and disturbing moon. I was able to observe 3 comets: C/2022 E2, C/2023 Q1 and C/2024 N4. Then the clouds moved in I had to close the observatoria. Also spectra in H-alpha region could be obtained from Be stars HD 22780 and BN Gem. SQM @ zenit was about 18.3 … 18.5 during the observations.
