Cassiopeia has a "W" shape to it. The last leg of that "W" are the stars Alpha and Beta. Draw a line through those stars and continue above the "W" for slightly more that the apparent distance between Alpha and Beta.
WHAT TO LOOK FOR:
M52 is a large, rich open cluster that is compressed in the middle. It is one of the richest open clusters. In binoculars, it will have a nebulous appearance, but these are stars that are easily resolved in the telescope.
