@freemo Why wasn't this used to solve the famous longitude problem?
@peterdrake Because it addresses lattitude (distance north and south) not longitude (location west and east). It wasnt used for latitude because using a sexton would be more accurate with the tools of the time.
@peterdrake oops that was not what i meant to say. I meant to say "lattitude or compass direction". let me correct that now (it will orphan your comments) thanks.
