    May I suggest that you use any table other than the Concise table in the NA? The other tables are easier to use and less likely to have some computation error creep in. Since you like the thin, LTM, try the also thin trig based tables such as HO 208 or Weem's Line of Position Book. You can check out these different methods of computation for yourself at the comparison of them that I posted here:

    Gary, you seem to have compared every sight reduction except the Concise table in the NA....

    I would be interested if you would expound your objections to this method.
