Globular cluster M4 - 14 March 2007

There are many interests crowded in constellation Scorpius and its surroundings. One of them is globular cluster M4.

I finished my night taking photos by set of shots of this globular cluster. It is one of the most conspicuous object in its category. It is not so concetrated like other globular clusters.
