The constellation contains the South Pole Star, sigma Octantis.

To find the South Pole, first find alpha and beta Kentaurus (bright stars near the Southern Cross). Draw a perpendicular midway between these two stars. Then proceed to the Southern Cross, extending the major axis (beta--alpha line) through the skies, until it intercepts the first line you drew. Where these lines meet you will find - in the same general region at least - the South Pole.
