In the lower right corner is IC 5168. This galaxy is not part of the compact group.

Stephan's Quintet consists of the galaxies:
NGC 7317, NGC 7318A, NGC 7318B, NGC 7319 and NGC 7320C.
The galaxies are the yellow areas from right to left in this order.

The somewhat bluish galaxy NGC 7320 is closer to Earth and lies in the foreground of the quintet. It does not belong to the quintet. Since this was determined later, it was replaced in the quintet by NGC 7320C (far left) to make it five galaxies again.

Below the center of the image is NGC 7550 and centered above is galaxy NGC 7549. The two galaxies form Arp 99.

To the left of NGC 7549 is NGC 7553.

To the right is NGC 7547.

At the bottom left is NGC 7558.

All five galaxies form the galaxy group HCG 93.

Arp 170 is in the center of the image and consists of the two galaxies NGC 7578A (lower right) and NGC 7578B above it on the left.

Arp 170 is part of HCG 94. This galaxy group consists of seven galaxies and continues above Arp 170 with galaxies NGC 7578C, (just to the left of Arp 170), PGC 70937 (above NGC 7578C), PGC 70943 (the large galaxy to the left of it), PGC 70939 (to the right of PGC 70943), and PGC 70941 (above PGC 70943).

In the center of the image is the interacting pair of galaxies Arp 150 consisting of NGC 7609 (top) and PGC 71077 (bottom).

To the right below is PGC 71074.

To the left below is PGC 71080.

All four galaxies form the HCG 95 galaxy group.

The large galaxy on the right is NGC 7674, which, with the galaxy NGC 7674A directly oblique above on the left, forms the galaxy pair Arp 182.

Together with the small galaxy PGC 71507 (diagonally below on the left) and the galaxy NGC 7675 (on the left), the galaxies form the galaxy group HCG 96.

The galaxy on the left is IC 5359.

The lower galaxy is IC 5356.

The bright galaxy at the top is IC 5357, with IC 5351 next to it on the right and IC 5352 above it.

In the center of the image is Arp 323 consisting of NGC 7783A (right) and NGC 7783B (left).

Together with the galaxy PGC 72806 (above) and PGC 72810 (diagonally left below) they form the galaxy group HCG 98.

In the original 1989 papers, only four galaxies are listed (Table 1, HCG 99, column 6) and Chart 99 on page 388: PGC 63 is at the top left and PGC 58 is immediately to the right. The large galaxy on the right is PGC 54. The left of the bottom two galaxies is PGC 60.

In the 1992 papers in which the radial velocities of the galaxies are considered, there is one more galaxy E: PGC 57 (right of the lower two galaxies).

NGC 7803 is the large galaxy in the center of the image.

To the left of it is PGC 108.

To the right of NGC 7803 is PGC 92.

The galaxy diagonally to the upper right is PGC 89.

The faint galaxy PGC 97 (diagonally to the left below PGC 108) is not part of the compact group.
