Many thanks for your responses.  Kind of scarry that I could make such
an easy math error.  I'm usually so concerned with possible errors in
the As and Bs looked up in H.O 211 that I guess I just kept
overlooking the error in LHA.  I have H.O. 249, but am on a kick right
now to see how accurate I can get using the approx. Sun decl./Eq. of
Time table that came with my Mark 3 Davis sextant, the condensed
Ageton table (Bayless), and the altitude correction page and the time
to arc conversion page (both from the Nautical almanac).  The whole
thing takes up 4 double-sided 8 1/2 * 11 sheets of paper.  Re-doing
some sights using this bare-bones kit has opened my eyes as to how
accurate you can get with so little to carry around.  That is, if one
can subtract correctly. Thanks again.   -- Joe
