    J S Letcher and Lunars
    From: David C

    I have scanned through my newly aquired volume  "Self Contained Celestial Navigation" by JS Letcher. The author is clearly a fan of lunars, describng a solo voyage without radio and a cheap timepiece. He became concerned about the accuracy of  the timepiece and used a lunar to to satisfy himself that he would make a safe landfall. The chapters dealing with lunars seem quite readable although I haven't read them yet.

    I believe that lunars went out of regular use in the 1850s. This is an example of a lunar  in 1963.

    Frank you have been scathing of Cotter's explanation of lunars. How well does Letcher do? Would his  lunar chapters  form a useful "Introduction to Lunars"?  Is it worth my while rto study the pages? A few years ago I tried to become a lunatic but quickly gave up. There seemed to be a zillion methods of clearing the sight when all I wanted was something that was easy and worked.
