comet and spectroscopic observations on 27 march 2022

The sky looks clear again for the whole night, so I decided to observe comets all night with the 0.4-m f/3.8 Orion Optics AG16 telescope. The following comets were observed: 4P, 19P, 29P, 67P, 70P, 71P, 99P, 104P, 116P, C/2017 K2, C/2019 L3, C/2019 U5, C/2020 F2, C/2020 H6, C/2020 J1, C/2020 K1, C/2020 M5. With the C11 + LHiRess III spectrograph I was able to obtain 2 spectra Zeta Ori and PZ Gem.
