    Re: book - the complete on-board celestial navigator

    In reply, I'll explain when I said 'briefly read through it...', I did work
    through the book doing and followed the examples, but lacking sufficient
    background, looked elsewhere to gain the prerequisite knowledge.  This is
    not Mr. Bennett's issue, but mine.  I think the Howell book introduces the
    subject in a much better way for the novice, and that's all I'm saying.  So,
    if the tables are troublesome, I'm just suggesting another source to help
    shed some light.
    
    What it did give me was the desire to understand what he presented in his
    tables, and try to understand what was behind them.  By chance,I found a
    copy of Ageton's Celestial Navigation, and after studying and learning that
    process, Mr. Bennett's book and tables did start to make sense.
    
    It is concise, and like the Ageton book of its' day, will be a very handy
    book to have on-board.  For the novice, there is no real substitute for a
    good tutor and practical experience, I agree.  However, I began my study of
    Celestial Navigation in this cold winter of the Midwest, and looked to
    books, and reference sources to increase my theoretical knowledge, to that
    end the Howell book served me better for that purpose alone.
