Description

Cassiopeia, a constellation in the northern sky, is recognizable due to its distintive "W" shape. The four brightest stars of Cassiopeia are all brighter than third magnitude. Because it lies in rich Milky Way star fields, Cassiopeia contains many deep sky objects, including open clusters and nebulae.

NGC 7822 (also designated Sharpless 171, SH 2-171) is a young irregular emission nebula and star forming region of about 40 light-years across, located some 3,300 light-years away at the edge of a giant molecular cloud toward the northern constellation Cepheus. It is home to the young star cluster Berkeley 59, whose stars are just a few million years old. A supernova remnant associated with NGC 7822, indicates that a massive star has already exploded.
