Alpha Trianguli Australis, the brightest star in this compact constellation southeast of alpha Centauri, forms the eastern corner of the large equilateral Southern Triangle.

The asterism is easily found with the naked eye. From alpha Centauri look just to the southeast from the twin stars alpha and beta Centauri.

Many fainter stars are grouped around alpha, including two Bayer stars: binoculars. Note that some are in the nearby constellations of Apus and Ara.
