between the clouds i did 2 spectroscopic observations, gam Cas and cx Dra on 26 april 2018 with c & L200 spectroscope with 1800 l/mm grating.
spectroscopic observations with C11 + L200 spectroscope with 1800 l/mm grating – H-alpha detail of Be-stars. gam Cas, shang-Ching HD20336
several spectroscopic observations are made on 19 april: gam Cas, VV Cep, kappa Draconis, omi Her, Menkalinan
follow-up spectroscopic observations are mede on 18 april: spectroscope L200 & 1800 l/mm grating (H-lapha detail): gam Cas, 48 Per,
After some weeks of clouds here i could make again spectroscopic observations with L200 spectroscope and 1800 l/mm grating. Observerd Be-stars are: gam Cas, HD138749 & kap Draconis.
again a clear evening, so i made a spectra of Be-star zetTau & 28Tau. data con you find vi links: zetTau and 28Tau.
First light of the spectroscopy setup in my new dome observatory. Observations made of the H-alpha of Pleione, 28Tau Be-star, to evaluate the Halpha V/R ratio and the radial velocity. These both parameters reflects very … Read more
The C11 telescope was send to Ralf Ottow for check and improving the collimation and optics. He checked the optics and he said that this C11 was better then C11 median telescopes and one of … Read more
