The border area between the constellations Cassiopeia and Cepheus is part of the northern Milky Way and contains a large number of interesting deep- sky objects, most of them open star clusters and nebulae. In fact, the whole area seems to glow in a more or less intense red nebulosity. The individual patches of nebulosity all have designations; the brighter ones NGC numbers, the fainter ones Sharpless (Sh2) numbers, and dark nebulae are taken from Lynd's Dark Nebulae (LDN) catalog. The most prominent deep-sky objects in this region are the open cluster M52 and NGC 7635, the Bubble Nebula, which belong to Cassiopeia; the huge emission nebula NGC 7822 in the upper right corner of the image; and NGC 7380 near the image's center, which is surrounded by the emission nebula Sh2-142.
