comet observations and spectroscopic observations of Be-stars during night 21/22 july

Although veil clouds were present and aircraft traces which disturb the clear sky, I did observe a number of comets and recorded  with the 2nd telescope spectra of Be-stars. With the selection of the images, reasonably useful data can still be extracted. The observed comets were: 21P, 29P, 78P, 37P, 137P, C/2012 K2, C/2012 K4, C/2017 M4, C/2017 M5 and C/2017 S3. The Be-stars , observed with BRIXIIS-II observatory are: cx Draconis and pi Aquarius.
