spectroscopic observations on 16 febr.

During a short period of clear sky, i could obtain 1 spectra in high resolution (R~15000) of Be-star: 123 Tau.

spectroscopic observations on 12 febr.

After a day of clouds and rain, I was able to take some spectra in the evening on a clear sky of following stars: zet Tau and PZ Gem

spectroscopi observations on 7 febr.

During a short period of clear sky i could obtain a high resolution spectra in H-alpha region of Be-star: zet Tau

comet observations on 19 jan.

the evening still looks good for comet observing, the moon does interfere a bit and the humidity is quite high. Clouds are predicted within a few hours. Comets that could still be observed are: 12P, 144P, 226P, C/2017 K2, C/2023 X1

comet observations on 16 jan.

agazin a clear night but cold (minus 4°C). I started in the early evening with observations of comets: 12P, 13P, 29P (small outburst), 30P, 126P (behind star), 150P, 226P, 227P, C/2021 S4, C/2022 E2, C/2023 T2.

comet observations on 10 jan.

again a clear cold night, several comets could be observed: 29P, 103P, 170P, 194P (not found), 310P (not found), 382P (not found), 404P, C/2021 S4, C/2022 E2, C/2022 U3.

comet observations on 9 jan.

a clear, but cold night (minus 6°C). I started with observations of come comets: 12P, 13P, 29P, 32P, 144P, 226P, C/2017 K2, C/2022 QE78, C/2022 U3. An object A10ZtNK, mentioned on the PCCP, was observed as well, cometary features could be detected.

defect CCD camera SX814 mono

I tried to start observations with the high resolution spectrograph and noticed a hugh kind of amplifier glow in the images of the SX814 mono of the spectrograph LHiReSS III. I tested this camera inside on darks and i get the same issue. Camera must be sent to the UK for repair.

spectroscopic observation on 7 jan.

a clear night, so i could obtain a spectrum of Be-star: zeta Taurus with the LHiReSS II and C11 cassegrain telescope in high resolution (R~15000)

comet and spectroscopic observations on 28 nov.

After long weeks of clouds and lots of rain, we had a beautiful clear day finally . In the evening I was still able to observe comet 12P/PONS-BROOKS and take a high resolution spectrum (of the H-alpha region) of a Be star omi Aqr. After about 1 hour unfortunately clouds came up again and I had to close the observatories. (Due to the lack of suitable reference stars in the FOV, I could not determine an Af(rho) parameter for comet 12P observation)
