A CCD photometric and spectroscopic study of the X-ray binary system 4U2129+47 (V 1727 Cyg) is presented. The results show that the object seen at the position of the source is a distant, mid-to-late F star reddened by E(B-V) = 0.5 mag, having constant magnitude and radial velocity. Upper limits to the light curve amplitude in the Gunn i band and to the radial velocity variations in the visual spectrum are 0.01 mag and 50 km/s respectively. Although the star probably is not the close companion of the neutron star in the X-ray binary, the F star may very well be at the same distance as 4U2129+47 and may be associated with it in a hierarchical triple system.
