Sh2-276, also known as the "Drunken Dragon Nebula," is a bright emission nebula located in the constellation of Cassiopeia. It is part of a larger complex of star-forming regions and is notable for its intricate structure and vibrant colors, which are produced by ionized gas and dust. This nebula is approximately 1,000 light-years away from Earth and spans about 30 light-years across. It is associated with the open cluster NGC 281, which contains young, hot stars that contribute to the nebula's illumination and shape. Sh2-276 is a fascinating object for both amateur and professional astronomers.
