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 identified 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 |
| Declination | +8 12 |
| Field of View | 40' x 27' |
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 |
Image details: 167 exposures of 120 seconds each,
taken with a ZWO ASI2600MC Pro imager and a 14" Meade LX850 telescope at f/5.6.
