    Re: Longitude by star clock

    Dear Frank! I dare to reply. :)

    Duane, there is a "much simpler" method that your's: just take a star globe (like this one), then "simply" turn and tilt it so that it comes into perfect correspondence to the sight of the sky above you. The rest is easy: your latitude is read on the altitude scale (against the elevated pole), your longitude is obtained by reading the SHAAries (or RA as on several globes is printed) against the meridian ring adding it with the GHAAries taken from NA for the moment of that observation.

    Why my method is preferable to your's? It immediatelly gives you the fix, - both your latitude AND your longitude. Simple! And better yet - it does not depend on the Polaris's visibility, - works in both hemispheres! Also it gives you the true North-South direction, - you do not need a compass now!

    Warm regards,
    Tony
