The multi-object spectroscopy technique was implemented on the Russian-Turkish 1.5m optical telescope (aka. RTT150)by modifying the slit wheel of its main instrument TFOSC (TÜBİTAK Faint Object Spectrograp and Camera). Remotelycontrolled rotating holders of the multi object masks were installed in the two nests of the slit wheel. The accuracy ofthe mask unit’s rotation is the order of 1 arcminutes, in which the image plane for 2 sources located at a separation of5 arcminutes corresponds to a positional accuracy of 0.1 arcseconds. To investigate the quality of the MOS technique inRTT150, the well-known merging galaxy cluster Abell 1914 was observed spectroscopically. The dispersion of the dierencesbetween known and RTT150 redshift estimations is 0.0006, which is good enough for cosmological studies.
