it was a clear night and i was able to observe several comets with my 0.4-m f/3.8 telescope. Comets that could be observed are: 43P, 117P, 130P, 328P, 487P, 493P, 496P, C/2021 S3, C/2022 N2, C/2023 A3, C/2023 Q1, C/2023 RN3, C/2024 M1, C/2024 N3, C/2024 N4. With the C11 telescope + LHiReSS III spectrograph i could obtain several spectra of Be-stars: V416 Aur, PZ Gem, psi Per, eps Cas, 11 Cam.
comet and spectroscopic observations on 28 nov.
After the clouds and the rain was gone, i could observe some comets: 43P, 130P, 493P, C/2021 S3, C/2022 N2, C/2023 A3, C/2024 M1, C/2024 N3. simultanously i could obtain, with the second observatory , several spectra of Be-stars: V801 Cas, gam Cas fot H-alpha and again gam Cas for the HeI-line, BK Cam.
spectroscopic observations on 25 nov.2024
During a short clear period, i could obtain a high resolution spectrum in H-alpha region of 48 Per. Then clouds drifted in again and I had to close the observatory
spectroscopi observations on 21 nov. 2024
a clear and cold night with some high clouds. I took this opportunity to obtain some spectra of gam Cas in H-alpha region (10x60sec) and He-I (7×600 sec) , HD 29866 (3x1200sec) and PZ Gem (8×1200 sec).
comet and spectroscopic observations on 12 nov.
spectroscopic observations on 2 nov.
This evening was a couple of hours clear sky. I could obtain high resolution spectra in H-alpha region for PZ Gem en HD21455.
comet and spectroscopic observations on 31 oct.
cloud-free sky but with high humidity, low transparency and a bit of fogging, I still opened the observatories for comet observations and capture spectra in High resolution. Comets that were observed are: 43P, 130P, 190P, 338P, 487P, 493P, C/2021 S3, C/2022 N2, C/2023 A3, C/2023 RN3 and C/2024 J2. spectra obtained are: gam Cas for H-alpha and HeI @ 6678 Angstr., Electra, Pleione, CT Cam . After midnight I closed the observatories due the fog rising too strongly
comet and spectroscopic observations on 11 oct 2024
a rare clear night was the trigger to make comets and spectroscopic observations once again. I was able to observe 7 comets including: 54P, 493P, C/2021 S3, C/2022 N2, C/2022 U1, C/2023 R1, C/2023 V1. Using the 2nd observatory for high-resolution spectroscopy, 2 spectra were recorded of Be stars QR-Vul (in outburst) and pi Aqr.
spectroscopic observations on 3 oct.
for a observing project, i could obtain 2 sepctra of Be-stars: QR Vul and V442 And.
spectroscopic observations on 1 oct.
To prepare for participation for an observing project, I observed gam Cas with the high-resolution spectroscope for both H-alpha line and the HeI line (@6678Á). (project starts on 1 November)
