spectroscopic observation on march 29.
I could obtain some spctra of Be-stars: gam Cas (HeI @6678), gam Cas (H-alpha @ 6562.8Å) en HD 24479

During this clear night with very good transparancy, i obtained 3 spectra : gam Cas (HeI @6678Å) , gam Cas (H-alpha @6562.8Å) and HD 24479.
The clouds drifted away and I could observe for several hours. On the agenda for spectral observations: nova Cas 2021 (V1405 Cas), gam Cas for h-alpha and gam Cas for HeI @6678Å. With the 0.4-m … Read more
Finally, another clear, cold night so that we could observe again. With the 0.4-m f/3.8 newton telescope I was able to observe a number of comets, unfortunately after a few hours I had problems communicating … Read more
It promises to be another beautiful clear night without a disturbing moon. I was able to observe some rather faint comets: 29P, 135P (not found), 141P, 173P, 415P, C/2020 M3, C/2020 U4, C/2021 C3. Also … Read more
it promises to be a clear night with cold temperatures (-4°C) I could observe several comets: 29P, 84P, 135P (not detected/near star), 141P, 398P, C/2019 L3, C/2020 N1, C/2021 A2. A high resolution spectrum was … Read more
the beginning of the evening, looked good, but soon there was more humidity in the air so the transparency went down. SQM in zenith was 18.5. I then started observing some comets: 29P, 156P, 162P, … Read more
some spectra could be obtained with the C11 + LHiResIII spectrograph: gam Cas (HeI detail @ 6678 Å), gam Cas (Ha-detail), HD 17505
a nice clear evening! after taking new skyflats with the Orion Optics AG 16 Newton telescope, I started observing some comets: 29P, 156P, 141P , C/2019 L3, P/2020 U2, C/2021 A2, C/2021 A4. With the … Read more
