after clouds where gone i could obtain a spectrum of PZ Gem for e short time of 40 min.
comet and spectroscopic observations on 24 oct.
After a very beautiful sunny day, the trend continued for a clear night. I therefore observed both comets and could obtain spectra. Unfortunately around 1 am – local time – during the night, I had to stop the observing due to clouds drifting in and a possible chance of rain.
Comets that i could observe are: 104P, 132P, 186P(not found), 324P(not found), A/2019 O2, C/2017 K2, C/2019 K7, C/2019 T3, C/2019 U5, C/2020 PV6, C/2021 K1, C/2021 E3, C/2021 O3. With the C11 and LHiResS spectrograph i could obtain high resolution spectra of: PZ Gem, V581 Per, V423 Lac, tet Ari, psi Per, pi Aqr, omi And, bet Psc, 18 Gem.
spectroscopic observation on 23/24 oct.
during this clear night with disturbing moon, i could obtain a spectrum of PZ Gem for a student project of univ. of Amsterdam (Netherlands). exposure-time: 7 x 1200 sec.
spectroscopic observations on 21 oct.
After a storm, clear skies came with occasional clouds. I was still able to record some spectra of some Be stars: 48 Per, V777 Cas, PZ Gem.
comet observation on 20 oct.
With a remote 0.61-m f/6.5 telescope from Telescope.Live, comet 57P was observed. An outburst could be observed (sudden brightening of the comet).
spectroscopic observations on 17 oct.
spectroscopic observations on 16 oct.
comet and spectroscopic observations on 15 oct.
according to the weather forecast there would be a clear night, unfortunately clouds are coming in very regularly here. I also have to deal with reciprocal problems of momentary loss of USB connection to CCD/and fo focuser which causes constant interruption of observations. Attempts were made to observe several comets including: 132P, C/2017 K2, C/2020 K1, C/2020 PV6, C/2021 D2, C/2021 E3. With the C11 + LHiress III spectrograph, a high-resolution H-alpha detail spectrum was taken from several stars: HD 216057, HD 21620, HD 21455, 14 Lac.
spectroscopic observations on 12 oct.
during a short period of clear sky i could obtain spectra (H-alpha-detail in high resolution) of following stars: eps Cas, BK Cam.
