Half-hours with the stars. A plain and easy guide to the knowledge of the constellations. Showing in twelve maps, the position for the United States of the principal star groups night after night, throughout the year, with introduction and a separate explanation of each map. True for every year
Richard A. Proctor's amateur star atlas, issued by G. P. Putnam's Sons in New York and London in 1887 for American sky-watchers learning the constellations month by month. Twelve circular maps print white stars, dotted constellation lines and stippled Milky Way on solid black, with horizon labels curving around the rim and constellation names set in fine spaced capitals.
