Abstract: We have optically identified a complete sub-sample of ROSAT All-Sky Survey (RASS) X-ray sources (Appenzeller et al. 1998) contained in 6 study areas (Zickgraf et al. 1997). Of the original 12x12 degree area near the NEP only one quarter was observed until now in order to keep the number of sources on a manageable size. This area is of particular interest because the RASS integration time is about a factor of ten longer than in the other areas and therefore a factor of 3-4 deeper in flux. We have started to observe the RASS sources in the remaining 3/4 of this area. Preliminary results are presented.
