| Description | The Shield was created by Johannes Hevelius in 1684 to honor the Polish King Jan III Sobieski, who led the defense of Vienna against the Ottoman Empire in 1683 — one of the most decisive battles in European history. Despite its tiny size it lies in an extraordinarily rich region of the Milky Way and contains the Wild Duck Cluster (M11) — one of the richest and most compact open clusters known, containing roughly 2,900 stars packed so tightly that early observers thought they resembled wild ducks in flight. The Scutum Star Cloud — a dense patch of the Milky Way visible to the naked eye — lies within its borders. |
