spectra H-alpha of Pleione on 1/5/7/8/12 febr. 2018

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 precisely the time of the periastron passage of this double star system. Observatiosn made on 1/5/7/8/12 febr. 2018.  spectra can you find via link: spectra 28Tau
