A practical handbook for amateur observers that describes telescope designs, mounts, eyepieces, and accessories while weighing the relative merits of large and small instruments. It offers clear, approximate methods for setting up equipment, sketching, measuring, and recording observations, then surveys observational targets: the Sun and Moon, the planets and their satellites, asteroids, comets, meteors, double stars, clusters, and nebulae. Numerous diagrams and plates support identification and technique. The text emphasizes accessible procedures for beginners, guidance on choosing suitable apparatus, and encouragement to cultivate careful, rewarding starlight-evening observation.
