was formed by La Caille between Ara and Sagittarius on the edge of the Milky Way, but in such irregular form that it encroached upon four of the old constellations; η Sagittarii having been taken as β to mark the Telescope's stand; d Ophiuchi for its θ; σ was in Corona Australis; and γ was the υ of Scorpio. Bode had it in his Gestirne of 1805 as the Astronomische Fernrohr, crowding it in between Sagittarius and Scorpio; but Baily and Gould restricted it to the south of Scorpio, Sagittarius, and Corona Australis.
Gould assigned to it 87 naked-eye stars, the brightest a 3½‑magnitude.
Small as these are, two bore individual titles in Chinese astronomy; α being known as We, Danger; and γ as the mythological Chuen Shwo.
The constellation culminates on the 13th of August, at the same time as Wega of the Lyre.
