    You know, Mike Pepperday has a nice little logarithmic method called
    Celestial Navigation with the S Table. Like Ageton he shows you the
    divided triangle (NASR doesn't; that's my big beef with it) and the
    formulas he uses. His triangle is divided like Dreisenstock's -
    perpendicular from the observer to the declination meridian. To
    understand the work forms for any of these methods, it's a big help to
    know that to multiply you add logarithms.
    
    The S Tables are nine pages. Pepperday's explication is a great deal
    more discursive than the NASR or Ageton or Dreisenstock. $9.95 from
    Celestaire. (You're welcome, Ken).  :-)
