Around between delta and epsilon Cassiopeiae, several open clusters are scattered and can be enjoyed only with small binoculars. You can see delta Cas in lower right hand side of the image.
A large cluster a bit upper left in the center is NGC663, gathering plenty of faint stars in 11 arc minutes.
Apparent shape of the cluster looks like a triangle through scopes.
And a tiny open cluster at the lower right-hand side of the NGC663 is M103, it's wonder that NGC663 wasn't registered in the Messier's catalogue in spite of that NGC663 is larger and brighter than M103.
Last, this picture shows you more faint clusters of NGC654 in right and IC166 in left are paralleled at the upper left hand side.
You can find much more pretty open clusters around this celestial field, they will jump into your field of vision one after another.
