comet and spectroscopic observations on 16 sept.

It turns out to be a good night for sightings, although there are sometimes veiled clouds. I started observing comets but after 5 comets I had to interrupt the observations because of clouds and gusts of wind. comets that I could observe: 8P, 11P, A/2019 U5, C/2019 L3, C/2019 O3. Simultanously i started spectroscopic observations with C11 + LHiResIII for high resolution : gam Cas for HeI detail @ 6678Å, gam Cas for H-alpha detail, HD 21362, phi And.
