Introduction to Navigational Astronomy

Every mariner who ever put to sea has marveled at the millions of tiny lights in the night sky.  Can they guide your passage?  See what early sailors saw, share their wonders, dream their dreams, all with the help of this fun-packed, non-technical guide to stars, planets, and major constellations of the Northern Hemisphere.

USPS Guides are available to members and the public at various marine supply stores, and also directly from United States Power Squadrons Headquarters by calling 1-888-FOR-USPS between 8:30AM and 4:00PM ET Monday through Friday, or on-line via the United States Power Squadrons Ship's Store.  Visa, MasterCard, Discover, and American Express are accepted.  These guides are also available to USPS members at reduced rates through their Squadron Educational Officer.
