M53 (NGC5023) is a small-sized globular cluster positioned just east of Virgo Cluster that contains uncountable galaxies. The cluster should be easily found at one-degree northeast of alpha Comae. M53 has a diameter of about 10 arc minutes and a magnitude of 7.6, the distance from the solar system is estimated about 65 thousand light years.
The globular has a very densed nucleus, this picture shows over-exposured. It tends to be impressive with larger scopes, which are needed to resolve the individual members.
M53 is one of few globular clusters visible in the spring skies; you can find a fairly vast globular cluster of M3 just northeast region of Canes Venatici.
