M4 - Globular Cluster in Scorpius
Copyright 2003 John Hodge
M4 is one of the nearest globular star clusters to us at a distance of only 7200 light-years. One interesting feature is a bar-like structure of 11th magnitude stars, visible in this photo running from the 11:30 position to the 5:30 position. This feature was first noted by William Herschel in 1793.
