Sh2-250 is a bright emission nebula located in the constellation of Cassiopeia. It is part of a larger complex of star-forming regions and is known for its striking appearance, which is primarily due to the ionization of gas by nearby young, hot stars. The nebula is approximately 1,500 light-years away from Earth. This nebula is also associated with the open cluster NGC 281, which contains several young stars that contribute to the illumination of the surrounding gas and dust. Sh2-250 is a popular target for amateur astronomers and astrophotographers due to its vivid colors and intricate structures.
