During the northern hemisphere fall and winter we are viewing a part of the night sky facing away from the center of the Milky Way. Thus, the region around the constellation of Cassiepeia are more sparsely populated with stars than the bright star clouds of the summer Milky Way, but nevertheless show an amazing number of star clusters and red Ha emission nebulae. The "showpiece" object in this area is undoubtedly the double cluster h+c, which technically is already part of the neighboring constellation of Perseus.
