In binoculars the cluster appears as a rounded hazy patch of light. There is a faint orangy-yellowish star at its edge. A medium sized telescope is needed to resolve its members.

M52 may prove a bit elusive; it isn't in a very notable part of the sky. One way of finding the cluster is to draw a line from alpha Cassiopeiae through beta, continuing it about the same distance (and a bit more).

If you place beta Cas at the southeastern edge of your glasses, M52 is at the opposite edge: binoculars.
