Right ascension is measured eastward up to 24 h along the celestial equator from the primary direction. Right ascension (abbreviated RA; symbol α) is the angular distance of a particular point measured eastward along the celestial equator from the Sun at the March equinox to the (hour circle of the) point in question above the Earth.

NGC 6712 is a globular cluster that was probably discovered by Le Gentil on July 9, 1749 when investigating the Milky Way star cloud in Aquila.He described it as a "true nebula," in contrast to the open star cluster M11.
The globular cluster was discovered in 1784 by the astronomer William Herschel with his 18.7-inch telescope and the discovery was later catalogued in the New General Catalogue. It is located 1.5 degrees south-southeast of Gamma 2 Sagittarii.
PKS 1830-211 is a gravitationally-lensed blazar in the southern constellation of Sagittarius, one of the most powerful such objects known. [4] It has a high redshift (z) of 2.507, an indicator of its significant distance. [2]
NGC 6522 is a globular cluster of stars in the southern constellation of Sagittarius.It was discovered by German-British astronomer William Herschel on June 24, 1784. The cluster has an apparent visual magnitude of 8.3 and an angular diameter of 9.4′. [3]
In the equatorial coordinate system, the right ascension coordinates of these borders lie between 18 h 14 m and 19 h 28 m, while the declination coordinates are between +25.66° and +47.71°. [12] The International Astronomical Union (IAU) adopted the three-letter abbreviation "Lyr" for the constellation in 1922.
