Scientific paper

In a course of a search for forbidden O II emission-line ojects associated with QSO absorbers, narrow-band and broad-band CCD images were obtained for eight quasar fields from 0.5 to 1 arcmin in radius. Observational techniques and details of obtaining and reducing the data are discussed, and 37 candidate forbidden O II emission-line objects are listed with fluxes from 1 x 10 to the -17th ergs/sq cm per sec to 75 x 10 to the -17 ergs/sq cm per sec in the emission line. Several fields were found to have multiple candidates, suggesting that groups with moderate amounts of star formation are common in the fields that were selected.
