Galaxy Cluster in Pisces
This galaxy cluster is located to the south of the Great Square of Pegasus, just across the border into the constellation Pisces. It contains numerous dim galaxies of various sizes and shapes.
The three brightest galaxies in the center of this image are, from left to right, NGC 7503, 7501, and 7499. They are all about magnitude 13, so they should not be too hard to observe through medium to large amateur telescopes. These are very distant galaxies indeed, estimated to be roughly 600 million light years away.
NGC 7501:
| Magnitude | 13.5 |
| Apparent Size | 1.0' x 0.9' |
| Distance (light yrs) | 610 million |
| Right Ascension | 23:10.5 |
| Declination | +7 35 |
| Field of View | 29' x 22' |
