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.
