The 1.2 m Schmidt telescope (UK) was employed to obtain two objective-prism plates and one direct plate of the area surrounding NGC 1097, centered on 2 h 44.2 m - 30 deg 29.0 min. Within a 9 square degree area surrounding NGC 1097, 37 QSO candidates are observed, bringing the total number of QSOs for this region to 43. The distribution of these QSOs around NGC 1097 was analyzed. Results show that the surface density of QSOs is very high near NGC 1097 and decreases from 15.2 to 2.0 per square degree with distance. The average density of QSOs in this region is approximately 4.8 per square degree. An obvious correlation is noted between the jets and the QSOs. It is suggested that the redshifts are noncosmological.
