The constellation Scutum as it can be seen by the naked eye The constellation Scutum in the night sky, enhanced for color and contrast. Scutum is not a bright constellation, with the brightest star, Alpha Scuti, being a K-type giant star [6] at magnitude 3.85. However, some stars are notable in the constellation.
Messier 26, also known as NGC 6694, is an open cluster of stars in the southern constellation of Scutum.It was discovered by Charles Messier in 1764. [a] This 8th magnitude cluster is a challenge to find in ideal skies with typical binoculars, where it can be, with any modern minimum 3-inch (76 mm) aperture device.

The Wild Duck Cluster (also known as Messier 11, or NGC 6705) is an open cluster of stars in the constellation Scutum (the Shield). It was discovered by Gottfried Kirch in 1681. [ 3 ] Charles Messier included it in his catalogue of diffuse objects in 1764.
Alpha Scuti, Latinized from α Scuti, is an orange-hued star in the southern constellation of Scutum. Originally part of the Aquila constellation, Alpha Scuti was a latter designation of 1 Aquilae. [9] It is faintly visible to the naked eye with an apparent visual magnitude of 3.83. [2]
IC 1295 is a planetary nebula in the constellation Scutum.It was discovered in 1867 by Truman Safford. [4] It lies roughly 4,700 light-years (1,500 parsecs) away. [2]The central star of the planetary nebula has a spectral type of DAO.56 [1] and shows the hydrogen deficient class object as hgO(H).
Gamma Scuti, Latinized from γ Scuti, is a single, [9] white-hued star in the southern constellation of Scutum. The apparent visual magnitude of 4.67 [2] indicates this is a dim star but visible to the naked eye. Based upon an annual parallax shift of 10.21 mas as seen from Earth, [1] this star is located about 319 light years from the Sun.
[1] [2] The cluster is located in the Scutum constellation. It had avoided detection for such a long time due to the extremely strong foreground extinction in its direction reaching 24 magnitudes in the visible light. Mercer 3 is probably situated at the distance from 4 to 8 kpc from the Sun and has a half-light radius of 0.7–1.5 pc.
