comet and spectroscopic observations on 25 april

we have a really exceptional period here in terms of the number of clear nights, barely seen in my period as an amateur astronomer. Another nice clear night and some comets observed, these are: C/2017 T2 (PANSTARRS) , C/2019 Y1 (ATLAS), C/2019 Y4 (ATLAS), 87P, and P/2019 Y2 (FULS). Also spectra were obtained with the C11 and LHiResIII spectrograph with 2400 l/mm grating (h-alpha detail). Observed stars: HD 208682, HD 195554, HD 79066 and eps Cas.
