finally another clear night, but cold. temperatures below zero. Comets that could be observed with my comet-setup were: 29P, 195P, 472P, C/2022 E2, C/2022 N2, C/2022 QE78, C/2024 M1, P/2015 CD60 and an object listed … Read more
During a short clear sky, i could obtain 2 spectra of Be-Stars: PZ Gem and gam Cas.
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, … Read more
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 , … Read more
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
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 … Read more
During a short period of clear sky, i could observe comet C/2023 A3 and spectroscopic observations of Be-star: gam Cas for h-alpha region and HeI emission @ 6678 Angstrom.
This evening was a couple of hours clear sky. I could obtain high resolution spectra in H-alpha region for PZ Gem en HD21455.
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, … Read more
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. … Read more
