M80 is a small, but fairly bright globular cluster at 4.5 degrees NW of Antares around the head of Scorpius.
The cluster has a bright central nucleus, its snug figure can be appreciated only through portable binoculars.
The concentration rate of the cluster is very high, it might be difficult to resolve the central structure of this globular.
While you can enjoy another globular cluster of M4 just west of Antares, M4 has very sparse concentration;
it's interesting to compare the difference of these two globular clusters.
