| Abstract: | We present CCD photometry of 16 Abell clusters and one cluster candidate found in POSS-II field 861. The images were taken
at the 0.9 m Telescope at Cerro Tololo, in the g, r and i filters of the Gunn–Thuan system. We tested the idea proposed by Garilli et al. (1996) that there is a population of unusually red galaxies which could be associated with either the field or clusters.
Garilli et al. (1996) suggest that these galaxies have anomalously red colours, but we find that these objects are all near the limiting
magnitude of the images (20m<r<22m) and have colours that are consistent with those expected for stars or field galaxies at z∼0.7.
