Abstract

Spectroscopic echelle observations of V751 Cygni and its nearby surroundings are presented here. Although long-slit observations show the presence of variable emission in the material around the object, the temperature and densities derived from [O II], [O III] and [S II] lines suggest that this material comes from the background and is not connected with the cataclysmic variable. An analysis of the radial velocity of the H alpha line gives an orbital period of 0.144584 days.
