by John Karl Many of the concepts used in celestial navigation, such as the celestial sphere, spherical geometry and log-trig functions, can be rather daunting. But there is one special sight that doesn't employ these mysteries, the famous noon sun sight. Learn the concepts of the noon sun sight and how to use your sextant. Until you make the move to full-fledged celestial navigation, this booklet offers a sight that is simple in concept and simple to work up without sight-reduction tables, almanacs or plotting. Softcover, 24 pages.
