spectroscopic and comet observations on 26 febr. 2021

After solving many technical problems, I can now observe comets again as the first evening before 2021. Comets on the menu were (unfortunately due to the full moon): 9P (not detected), 29P, 156P, 409P, C/2020 T2, C/2020 V2, C/2021 A2, C/2021 A4. With the LHiResIII spectrograph a spectra of following stars was obtained: HD 70340, gam Cas, 25 Ori.
