Description

The #questionmarknebula (#ngc7822) and the #littlerosettenebula (#sh2170) straddle the border between the constellations of Cepheus and Cassiopeia, and lies approximately 3000 light-years from Earth. This mostly H-alpha emitting massive star formation region contains every major type of DSO but one: emission nebulae, reflection nebulae, dark nebulae, planetary nebulae, visible galaxy, and open star cluster. There is no globular cluster.
