A bright star that guides the course of a ship (8)

I believe the answer is:

lodestar

(Other definitions for lodestar that I've seen before include "Travel guide" , "Heavenly guide" , "In navigation, celestial reference point" , "Guiding light; leotards (anag.)" , "Guiding light in sky" .)

I've seen this clue in the Sydney Morning Herald.
