Comet and spectroscopic observations on 2-3 april

a very clear night but with moonphase of 0.91 we had disturbing moonlight. SQM @ zenit was 18.9. I could observe some comets: 29P, 364P, C/2019 U5, C/2020 R7, C/2022 L2 and object C8AY5Y2 mentioned on the PCCP. Spectroscopic observations in high resolution (R = ca. 15000) were made from emission B-stars: 53 Bo├Âtis, kappa Draconis and CQ Ursa Major with my C11 + LHiRess III spectrograph with 2400 l/mm grating.
