Astronomy with an opera-glass: a popular introduction to the study of the starry heavens with the simplest of optical instruments, with maps and directions to facilitate the recognition of the constellations and the principal stars visible to the naked eye;
A popular observing guide by Garrett P. Serviss, published by D. Appleton in New York and London in 1888 for amateur stargazers using opera-glasses and small field instruments. The plates are circular black fields printed with white stars of graded size, some marked with letters or stippled nebulous patches, giving designers ready-made telescope-view roundels, star shapes, and high-contrast night-sky textures.
