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.
