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.
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)
comet observation on 24 nov.
Comet 12P/PONS-BROOKS cannot keep hiding behind the clouds and rain showers. on Nov 24, I was ready in the observatory and in between the clouds, a very brief clearing and was able to observe the comet briefly by taking 3 sub-images.
comet observations on 20 nov.
After a cloudy day with rain showers in the evening, there was a brief clearing for about 1 hour and I was able to observe comet 12P between the clouds. After an hour, clouds but also fog gathered so I had to close the observatory.
comet observations on 17 nov.
After a day of rain, the skies cleared and it was a reasonably clear night with very high humidity. The high humidity caused some technical problems at start of observing. Eventually after about 2 hours, I was able to start anyway. Subsequent comets could be observed until clouds drifted in again. 12P, 32P, 126P, 144P.
