there is also a more crude way to get close
1 locate crux and the pointers
2 draw imaginary line vertically through crux Gamma crux through Alpha crux
3 drop another imaginary line perpendicular to the line of the pointers
4 where the two lines intersect then drop another line vertical to the ground and that will be close enough to due south that you can start aligning, you may need to turn a little east or left but good to know if out at a dark site without technology
