comet and spectroscopi observations on 13 april

This evening started well with a nice clear sky, but after an hour of observations, clouds floated in and unfortunately the observations had to be stopped. Two comets were observed with the 0.4-m f/3.8 newton: C/2017 T2 and C/2019 Y4. With the C11 and spectrograph 2 spectra were captured 53 Boo and HD 50658.
