Astroarts StellaNavigator 		Scutum, the Shield, is a minor constellation found just north of Milky Way in Sagittarius. Although the shape of constellation itself is not very obvious, you can be fascinated with the beauty of the Milky Way in that with binoculars.
J. Hevelius, a Polish astronomer, invented the constellation. The constellation had the proper name of Scutum Sobieskii. Jan Sobieski was the king of Poland. He repulsed the Turks that tried to attack Vienna in 1683. Hevelius commemorated this event with the inclusion of Scutum Sobieskii in summer sky in 1690.
