  Title: DEEP OBSERVATION OF QSO CLUSTER II: THE NORTHERN PEAK                           


Abstract:
 We observe one of the two peaks of the QSO cluster (z=1.0-1.2) discovered by
 Crampton et al. 1989. The other peak was observed with ASCA in 1995 as AO-3 target
 with 100 ksec exposure. Our preliminal analysis of the data suggests that observing
 the QSO cluster region is indeed very fruitful. 1. We may detect more QSOs than a
 blank sky survey in a field of view. We can not only compair Lx and Lopt but also
 obtain distribution of the X-ray hardness-ratio for QSOs at the same redshift. 2. We
 have much more chance to discover "Type-2 QSO" than in general field, since they may
 be in the same distribution as the ordinary optical QSO.

REMARKS:  THERE IS SOME LIMIT FOR THE ROTATION OF FOV. IF 4CCD FAINT MODE WILL NOT
          BE FEASIBLE, WE WILL CONSIDER TO USE 2CCD MODE.
