again a clear night. i could start around 23h local time in evening twilight with capturing a spectrum of alpha Draconis (spectroscopic double starsystem) in h-alpha region in high resolution (R~15000) with LHiRess and C11 … Read more
still very clear night with good transparancy. I took a spectrum in high resolution of H-alpha region of alpha Draconis in participating of the STAROS project.
a clear grey night (sun hole not lower than 18° below the horizon) again a high-resolution spectrum in H-alpha region of Alpha Draconis for STAROS project
It gets dark later and later each time and last night started high resolution spectrum of Alpha Dra for HR spectrum in H-lapha region. data can be found in the STAROS database .
a clear night but cocktail of low transparancy, wind gusts and almost full monn (99%) disturbing ths observations/ comet that where observed are: 12P, 80P (not found), 103P (not found), C/2019 T4, C/2020 R7, C/2020 … Read more
