Although not a large constellation, Scutum contains several [[open cluster]]s, as well as a [[globular cluster]] and a [[planetary nebula]]. The two best known [[deep sky object]]s in Scutum are [[Wild Duck Cluster|M11]] (the Wild Duck Cluster) and the [[Open Cluster M26|open cluster M26]] (NGC 6694). The globular cluster [[NGC 6712]] and the planetary nebula [[IC 1295]] can be found in the eastern part of the constellation, only 24 arcminutes apart.

The most prominent open cluster in Scutum is the [[Wild Duck Cluster]], M11. It was named by [[William Henry Smyth]] in 1844 for its resemblance in the eyepiece to a flock of ducks in flight. The cluster, 6200 light-years from Earth and 20 light-years in diameter, contains approximately 3000 stars, making it a particularly rich cluster. It is around 220 million years old,<ref>{{cite journal |title = So, Where Are the Wild Ducks?! |last = MacRobert |first = Alan |journal = Sky and Telescope |date = September 2012}}</ref> although some studies give older estimates.<ref>{{citation
