spectroscopic and comet observations on 2 may

during this clear evening i could observe some comets, I can only start later in the evening because of the sun going down later and later at this time of year. coemts that could be observed are: 117P, C/2017 K2, C/2020 R4, C/2020 T2 . With the LHiResIII high resolution spectrograph, I was able to observe the following stars: Sheliak, HD 112028, HD 50658, 18 Lyr.
