M15 (NGC7078) is a globular cluster found at the nose of Pegasus, about 4 degrees NW of epsilon Pegasi.
The cluster is a medium sized one with a diameter of 12 arc minutes and looks like a coma of comet with magnitude of 6.
A medium-sized telescope should be needed to resolve the individual stars.
You can find a star of 6th magnitude just 17 arc minutes east of the cluster, these two objects have almost same brightness.
It's slightly contrastive between the star and the dimmed cluster.
In autumnal southern sky, there is another major globular cluster of M2 in Aquarius about 13 degrees south of M15.
M15 and M2 are positioned at almost same right ascension, and they have almost same size and brightness, look like the "Twin" globular clusters.
