The Coma Star Cluster, Melotte 111, in Constellation Coma Berenices
Melotte 111, the Coma Star Cluster, is one of the largest and nearest open clusters visible from Earth. Spread across nearly 7.5 degrees of sky in the constellation Coma Berenices, this loose but physically bound group of roughly 40 bright stars is a rewarding wide-field target: capturing its full angular extent requires focal lengths well below 200mm.
