Below: This cropped detail shows the trio of galaxies (from left) NGC 7599, NGC 7590 and NGC 7582.
Below: Another detail showing the fourth member of the group, NGC 7552.
Below: The fifth (of five) NGC objects in the wide-field image, NGC 7632.
Below: There are numerous other galaxies throughout this field, most of them lying at distances of hundreds of million of light years, with at least three catalogued galaxy clusters visible.
Galaxy cluster Abell 1111 (at centre).
Galaxy cluster Abell 3998 (at centre). The large bluish object at top is irregular galaxy ESO 347-8 (not part of the Abell cluster, which is vastly more distant).
Galaxy cluster Abell 1106 (at centre).
This region (to the right of NGC 7552 in the wide-field image) is teeming with background galaxies.
