Black patches of the Milky Way separate Cassiopiea and Cepheus, the mythological Queen and King of Aethiopia. Nearer to us, over dark clouds are some colorful nebulas such as Sh2-155 (Cave Nebula), Sh2-154 and Sh2-135. There is a prominent, extremely big but not-so-dark nebula, LDN1238, left of the center. Between those dark clouds, standing out are Sh2-157 and Sh2-162 (Bubble Nebula, though the Bubble itselft is not resolved at this image scale). The lower right also hosts the Sh2-142, Sh2-135, Sh2-132 and LBN431 nebulas and the relatively bright, naked-eye star ζ Cep. Overlapping LDN1180 there is a faint nebula that doesn't seem to be listed in Sh2 and LBN catalogs.
