A UV image in the direction of Ophiuchus, obtained with the FAUST instrument is analysed. Suitable candidates as unrecognized subluminous stars are selected comparing the observed UV flux to the predicted one. The uv-excess objects were observed at the 1.0 m Wise telescope. This method yields to the detection of eight broad Balmer lines objects. Six are classified as sds and two wds, comparing the Hbeta line profile with that of stellar model atmospheres.
