Weems & Plath Star Finder 2102D

 

This Star Finder graphically portrays the altitude and azimuth of the fifty-seven numbered stars in the Air and Nautical Almanacs. Additional celestial bodies may be plotted on the star base. Special diagrams permit rapid check of hour angle, and also provide means of finding the altitude and azimuth of unplotted bodies, or the identification of unplotted bodies from known altitude and azimuth.
