weatherconditions are a clear night but with low transparancy, SQM in zenit was about 19.0. comet that could be observed with the 0.4-m f/3.8 corrected newton (OO AG16) are: 22P, 61P, C/2020 F5, C/2020 H6, … Read more
with the C11-cassegrain telescope + LHiRess high resolution spectrograph (grating 2400 l/mm) i could obtain some spectra in H-alpha region of Be-stars: HD 21455, omi Cas, psi Per, V2120 Cyg.
Several high resolution spectra of the H-alpha region could be obtained from Be-stars: gam Cas, HD 6343, phi Per, V764 Cas.
with full moon and clear sky, i could obtain a spectra of CT Cam.
it was a nice clear evening after the clouds cleared. The moon phase was 0.49 but quite low on the horizon. I noticed on the SQM meter reading 19.45, normally i can get about 19.3. … Read more
