M30 is infamous as being the final object necessary to complete a springtime
Messier Marathon. It is about 70 light years in diameter and is some 25,000

This fairly large and concentrated globular cluster lies in eastern Capricornus
to the east of a prominent arc of stars. It was partially resolved at 118x,
showing a bright, concentrated core. At 202x the two streamers of outlying
stars that give this globular its distinctive appearance were quite apparent.
