    Well, I seem to have miscommunicated my answer, based upon the 
    misinterpretation of it through various postings.
    
    I don't think John's problem is parallelism.  
    
    I do think his problem is holding the sextant steady.  When you take a lunar, 
    the moon and the star brush each other as you wobble the scope.  One goes 
    left, the other goes right.  And hence the reason why I said the plane of the 
    arc in the same plane as the two objects.  In this case both objects are the 
    same object, just on a different optical path.
    
    Best Regards
    Brad
