Astronomy with an Opera-glass was Garrett Serviss’s happiest idea: proving that the humblest optical instrument in the house opens the heavens. Season by season he walks the constellations, showing what a simple glass reveals — the Pleiades multiplied, the Milky Way resolved, Jupiter’s moons on a steady night.
It made thousands of astronomers out of opera-goers, and its sky is still up there. Download the free EPUB, find any pair of binoculars, and begin.
