A clear evening after the clouds disappeared and I had the opportunity to observe some comets, unfortunately with occasional technical problems (cable that got stuck behind an obstacle and stopped the mount): 117P, 409P, 413P, C/2021 A1. With the LHiResIII spectroscope and C11 telescope some spectra of Be stars could be recorded: BK Cam, HD 24479, HD 174237, HD 195554, HD 175863.
