Five galaxies are rather distant (about 250 MLY):   a small NGC 7320c (to the left), larger NGC 7319, overlapping NGC 7318a + 7318b  and NGC 7317 (other small one to the right). The last (and apparently largest "member" of the group, blue spiral galaxy NGC 7320 is far in the foreground, only some 40 MLY from us.
