  Here we report our first spectral observations of Be/X-ray and gamma-ray
binaries obtained with the new Echelle spectrograph of the National
Astronomical Observatory Rozhen. For four objects (LSI+61303, gamma Cas, MWC
148, 4U 2206+54), we report the parameters and estimate the sizes of their
circumstellar 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 through
the disc. The flank inflections of H-alpha can be connected with inner ring
formed at the periastron passage or radiation transfer effects. We point out an
intriguing similarity between the optical emission lines of the $\gamma$-ray
binary MWC 148 and the well known Be star $\gamma$ Cas.
