Galaxy Cluster in Pegasus
Galaxy clusters such as Pegasus I are among the most distant objects that can be observed through ordinary amateur telescopes. Even fairly small telescopes can show the two brightest members of this cluster, the elliptical galaxies NGC 7619 and NGC 7626. With larger telescopes, some of the dimmer galaxies can be seen. However, some of the smallest and dimmest galaxies visible in this image (listed in the Principal Galaxy Catalog, and labeled with "P" in this image) are a challenge to see in the largest amateur telescopes.
NGC 7619:
| Magnitude | 12.3 |
| Apparent Size | 2.5' x 2.3' |
| Distance (light yrs) | 170 million |
| Right Ascension | 23:20.2 |

NGC 7626:
| Magnitude | 12.3 |
| Apparent Size | 2.6' x 2.3' |
| Distance (light yrs) | 170 million |
| Right Ascension | 23:20.7 |
| Declination | +8 13 |
