The weather conditions are excellent: no wind, clear night, no clouds, dry air… i observed several comets: 4P, 29P, 67P, 104P, C/ 2019 L3 and a possible comet mentioned on the PCCP (40 x 120 sec. hours observation). With the C11 + LHiRess spectrograph i could capture spectra of PZ Gem for 3 hours (9 x 1200 sec)
