Here we report our first spectral observations of Be/X-ray and gamma-raybinaries obtained with the new Echelle spectrograph of the NationalAstronomical Observatory Rozhen. For four objects (LSI+61303, gamma Cas, MWC148, 4U 2206+54), we report the parameters and estimate the sizes of theircircumstellar discs using different emission lines (H-alpha, H-beta, H-gamma,HeI and FeII). For MWC 148, we find that the compact object goes deeply throughthe disc. The flank inflections of H-alpha can be connected with inner ringformed at the periastron passage or radiation transfer effects. We point out anintriguing similarity between the optical emission lines of the $\gamma$-raybinary MWC 148 and the well known Be star $\gamma$ Cas.
