    Certainly there are other methods.  But the issue is what do the
    majority of long distance voyagers use for celestial?
    
    I've also been told that most of them do only sun sights -- a morning
    shot advanced to cross with a mid-day shot, with the latter advanced to
    cross with a late afternoon shot.
    
    If one is going to do only sun shots, then I see two 21st century
    choices:  buy Volume 2 of HO249 each year, or buy a copy of the Nautical
    Almanac each year and use a calculator (with the NASR as a backup) for
    sight reduction.
    
    For me personally, I'd probably do the latter since that all bodies at
    all latitudes, albeit with perhaps a tad more work in sight reduction.
    But what's most important to any voyager is to have a method that he/she
    is comfortable with and understands reasonably well.
