comet and spectroscopic observations on 20 dec.

after a rainy  and cloudy day, the evening was promissing for a long clear sky. I could start with comet observations of comet C/2018 N2 (ASASSN), unfortunately i must interrupt the observations due windghusts which disturbed the observations a lot (roll-off observatory). With the dome and C11 + LHiRessIII i could observed several Be-stars and stars to obtain high resolutions psectra around the H-alpha wavelength. stars which are observed are: Pleione, zet Tauri, V801 Cas, 120 Tauri, 69 Ori, 28 Ori, 25 Ori, VV Cep.
