On the border between Cassiopeia and Cepheus lay the Cas OB2 association and the large HII regions Sh2-157 (Lobster Claw), Sh2-161 and Sh2-162 (the famous Bubble Nebula). Smaller but bright, we also find Sh2-156, Sh2-158, Sh2-159 and Sh2-163. Another prominent object in this region is the globular cluster M52.
