this evening i could after some technical issues due the very high humidity (> 90% RH) starting with observing comets. Comets wich could be observed are: 22P, 61P, 196P, C/2020 F5, C/2021 T4, C/2021 Y1, … Read more
during this clear night, but low transparancy, i obtained several spectra of Be-stars: ups Cyg, PZ Gem, HD 2012044, HD 201836, HD 23800, 48 Per.
the evening and night looks promising, with a very good transparancy and SQM of 19.2 … 19.5 , which is pretty good for my surrounding, i could observe some comets and could obtain some spectra … Read more
after a very nice day we have a clear night, with some little fog and lower transparancy and SQM about 18.9 in zenit. I could observe several comets with my 0.4-m f/3.8 newton telescope: 22P, … Read more
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
