Complete 2025 Nautical Almanac including all daily pages, the Pole Star Tables, and all interpolation and correction tables available in the official Nautical Almanac.  Everything you need to find the GHA and Declination of the observed body, correct your sextant altitude observation (Hs) and produce the observed altitude (Ho) needed for the sight reduction, and determine solar system event times.

​

Note that it does NOT include other sections of the official Nautical Almanac not mentioned above (detailed explanations, concise sight reduction tables, etc.).

This book is compiled from pages that are generated and can be output/printed from the ezAlmanacOne app.

If you don't have the app or just want a pre-printed Nautical Almanac as a backup on a passage, this book is an economical version of the same data you will find in the USNO or commercial version of the Nautical Almanac.
