Spectroscopic observations are made of Be-stars: HD 46264, zet Tau
During some hours, it was almost clear and i could obtain observations of following comets: 29P, 114P, C/2017 T2. Also sith the C11, i could obtain spectra of Be-stars of: Pleione, zet Tau, HD 32343, … Read more
during this clear night, i made observations of Be-stars for H-alpha detail in high resolution. Starch which a spectrum is obtained are: Pleione, HD 50083, HD 34921, 1229 Aur – HD 50658
in the late evening i started with taken a spectrum of Be-star HD 20134 with C11 + LHiResIII spectrograph with 2400 l/mm grating for H-alpha line detail.
a lot of clouds with periods, but i could obtain 3 spectra during this evening. Be-stars which are observed for H-alpha detailed spectra (R > 13000) are: Pleione, V442 And, HD 51506
