between the clouds, i could obtain 1 spectra of 25 Cyg for about 1/2 hour, after that it was again cloudy for the rest of the night.
there was a short period of almost clear sky a
spectroscopic observation with C11 and LHiResIII spectrograph with 2400 l/mm grating: 8 Lac and also a star from TESS list: V357Lac – HD 212044. There was a huge temp. drop from 24 degr. to about … Read more
there were several periods of stubborn cloud cover that only moved very slowly. Still some periods of clear sky at full moon. I could record 2 spectra of: VV Cep and cx Draconis. also some … Read more
several spectroscopic observations are obtained from stars: VV Cep, gam Cas, LQ And, omi Cas, phi And, pi Aqr. Unfortunately I sometimes had to interrupt the observations with the occasional cloud fields that came over.
spectroscopic observations are made with the C11 and LHiResIII on several Be-stars: V1466 Aql, V1339 Aql, QR Vul
Between a few showers it was clear and transparent. I have taken advantage of these opportunities to perform some comets and spectrum observations. Comets that I’ve observed are: 29P, 114P, 260P, C/2016 A1, C/2018 N2, … Read more
