===Method one: The Southern Cross=== The south celestial pole can be located from the [[Crux|Southern Cross]] (Crux) and its two "pointer" stars [[Alpha Centauri|Ξ± Centauri]] and [[Beta Centauri|Ξ² Centauri]]. Draw an imaginary line from [[Gamma Crucis|Ξ³ Crucis]] to [[Alpha Crucis|Ξ± Crucis]]—the two stars at the extreme ends of the long axis of the cross—and follow this line through the sky. Either go four-and-a-half times the distance of the long axis in the direction the narrow end of the cross points, or join the two pointer stars with a line, divide this line in half, then at right angles draw another imaginary line through the sky until it meets the line from the Southern Cross. This point is 5 or 6 degrees from the south celestial pole. Very few bright stars of importance lie between Crux and the pole itself, although the constellation [[Musca]] is fairly easily recognised immediately beneath Crux.
