The Star Finder 2102-D is an invaluable tool for celestial navigators to plan star and planet sights. It can also be used by amateur star gazers for general star identification.
The Weems & Plath Star Finder consists of star altitude and azimuth templates centered at 10' intervals of latitude, a median angle diagram, and instruction sheet all enclosed in a soft plastic sleeve. Every star listed in the Air and Nautical Almanacs can be located using these graphic transparencies, while additional celestial bodies can be plotted on the star base. Special diagrams permit rapid checking of hour angles and allow you to chart the heavens.
