with the 0.4-m f/3.8 newton telescope is observed some comets: C/2017 K2, C/2020 M5, C/2020 R4, C/2020 T2, C/2021 A1. With the C11 + LHiResIII spectrograph, i could take spectra of following stars: nova V1405 … Read more
during a short period of clear sky i made spectroscopic observations of: 28 Cyg
during this evening with clear sky, i observed some comets: C/2017 K2, C/2020 T2, C/2020 R4. With C11 + LHiResIII, i could obtain spectra of nova V1405 Cas 2021.

after the clouds where gone, i could start with taken some spectra of: Novae V1405 Cas 2021, gam Cas (H-alpha detail @ 6562.8 Å) and gam Cas for HeI-detal @ 6678 Å
during e short period of clear sky, i could obtain again a spectrum for H-alpha detail for novae V1405 Cas.
Between the showers was a period of about 1.5 hours of clear sky. I was able to record spectra of nova Cas 2021 (V1405 Cas) ( see ATel #14577) and HD 174179
during a short period of clear sky i could obtain a spectrum of HD 24479 for H-alpha detail @ 6562.8Å.
