    Re: Navy MK 5 Octant Using Natural Horizon

    Greg,
    This is what I would expect with a good sextant,
    powerful scope, perfect horizon and experienced observer.
    
    Which shows again how incredibly good your bubble octant series was:-)
    
    Alex.

    Typically a spread of 1' is good.
    Average intercepts vary as the result of measured accuracies of H.E. ,
    I.C., and time.
