Originally named Scutum Sobiescianum (Shield of Sobieski) to commemorate the victory of Christian forces led by Polish King John III Sobieski in the Battle of Vienna in 1683, the name was later shortened to Scutum. This is a small, dim constellation located between the tail of Aquila, above the head of Sagittarius, and to the left of Ophiuchus. Scutum reaches its highest nightfall ascension in August. It contains two Messier star clusters, M11 (the Wild Duck Cluster), and M26 (NGC 6694).
