An east side of Abell 1656's nucleus. The brightest galaxy on the west is NGC 4884. I confirmed galaxies IC 4033, IC 4021, IC 4026, IC 4033, IC 4040, IC 4041, IC 4045, IC 4051, NGC 4882, NGC 4884, NGC 4894, NGC 4898, NGC 4906, NGC 4908 and NGC 4042. The most of them are very faint and stellar, but there are also some brighter members on the east. Again, a very difficult field because of numerous galaxies.
