C AD E T
168.7° 11.3°E 180°

so if you want to point your mount due south, your magnetic compass should read 168.7°

Hope this helps and I haven't added to the confusion

Rob,

The one and only clear and practical post on this matter.

From another mariner, who cannot figure why landsmen can make such a problem out of this!
