comet and spectroscopic observations on 22 may

nights are getting very short and I could only start observations of comets and spectroscopy of Be stars around 11pm. Comets I observed are: 29P, C/2023 A3, C/2023 H5. The nearly full moon is quite disturbing especially with the humid air. Spectra that could be obtained in H-alpha region and high resolution (R~~15000) are: omi Hercules and HD 175863. (data can be found in the BeSS database)
