Move your mouse over the image above to get a version with constellation lines, deep-sky objects and labels drawn.

In the image above, north is to the right and east is up.

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.
