Based on the material of multiple high-resolution R=60 000 observations conducted on the 6-m telescope (BTA) of the Special Astrophysical Observatory in combination with the Nasmyth Echelle Spectrograph (NES), we closely studied the features of the optical spectrum of the star MWC17 with the B[e] phenomenon. In the wavelength interval of 4050-6750 A, we identified numerous permitted and forbidden emissions, interstellar Na I lines, and diffuse interstellar bands (DIBs). Radial velocities were estimated from lines of different origin. As the systemic velocity, Vsys, the velocity of the forbidden emissions can be accepted: 47 km/s (relative to the local standard V lsr=-42 km/s). Comparison of the obtained data with the earlier measurements allows us to conclude on the absence of considerable variability of spectral details.
