Rapid Sight Reduction Tables for Navigation consists of three volumes of comprehensive tables of altitude and azimuth designed for the rapid reduction of astronomical sights. These volumes were originally entitled Sight Reduction Tables for Air Navigation. The modified title and change in emphasis of the explanation, examples and auxiliary tables are due to their popularity for marine navigation. However, the United States edition remains unchanged in title and content.

The present volume (Volume 2) contains tables for integral degrees of declination, for latitudes 0°-40° north and south, and provides sights of the Sun, Moon and planets.
