LONG TERM ALMANAC 2000-2050
by Geoffrey Kolb

As many know, the Nautical Almanac repeats itself every 4 years for the sun and stars.,but not for the moon and planets. This book cleverly reprints the GHA and dec for the sun, and GHA for Aries on each day of the month, for each of 4 years. Its like you have four consecutive Almanacs, but only taking the space of 64 pages.

Then a form of the existing sight reduction tables found in the Nautical are also reprinted (with simple instructions) so that the book becomes a stand-alone way to compute celestial lines of position.

This neat little book stows nicely in a sextant case, and makes a great alternative or emergency back-up for those not wanting to carry a full set of tables. We do not, however, recommend it for the new beginner, as the tabular format will not match that used in celestial navigation texts.SC, 111 pages, 2008. SW 1 lb.
