comet and spectroscopic observations on 2 oct. 2022

it was a nice clear evening after the clouds cleared. The moon phase was 0.49 but quite low on the horizon. I noticed on the SQM meter reading 19.45, normally i can get about 19.3. I have never seen this here in my backyard. Could the energy crisis be in between for something that lights get extinguished more ? Anyway… i started with some comets including: 22P, 61P, 285P, 286P, 395P, C/2019 O3, C/2020 H6, C/2020 F5, C/2022 E3, C/2022 L2. With my 2-nd setup C11-telescope and the LHiRess high-resolution spectrograph, I was able to record some Be stars a spectra. These are: V378 And, HD21620, 16 Peg and 31 Peg.
