Globular clusters are not formed within the galaxy structure, but usually large numbers of them form a halo around the main galactic structure.
Globular clusters usually require a larger telescope and higher magnification to observe to best effect, although the larger and closer ones can be spectacular in small instruments.
Stellar concentration is average for a globular cluster and it is one of the metal-richest globulars.

 Globular Star Clusters
Globular clusters are gravitationally bound concentrations of approximately ten thousand to one million stars, spread over a volume of several tens to about 200 light years in diameter.
Globular clusters typically contain a number of variable stars, in particular RR Lyrae stars which were once called "Cluster Variables" because of their abundance in globulars.
It is perhaps a bit surprising that almost all globular clusters seem to be of about the same age; there seems to be a physical reason that they all formed in a short period of time in the history of the universe, and this period was apparently long ago when the galaxies were young.

Globular clusters are a gravitationally bound concentration of a massive amount of stars.
Globular clusters are also believed to be very old and formed from an earlier generation of stars due to the fact that they are much lower in heavy element abundance than other stars such as the Sun.
This particular globular cluster, M14, was one of the original discoveries of Charles Messier who documented it on June 1, 1764.
