This image is purposefully left full frame to show the richness of the colorful star field, even though it makes the clusters less dominant in the image.

Forming a triangle of clusters just NNW of Kappa Cassiopeia (the bright, blue star), starting closest to Kappa and progressing clockwise are King 14, NGC 146 and NGC 133. Surprisingly, since it has no NGC designation, King 14 is the dominant and richest cluster of the three. NGC 133 is the poorest in the NW corner of the triangle, looking like no more than a bent "L" of 4 yellow stars.
