Atlas der Planetarischen Nebel – Volume 1

Ronald Stoyan’s large-format atlas is devoted to planetary nebulae, the expanding gas shells of dying stars. Volume 1 covers 176 objects between 0 and 11 hours of right ascension. Each entry combines discovery history, current astrophysical data and visual observing guidance. The selection ranges from well-known Messier and NGC objects to fainter targets from specialist catalogues.

Entries provide coordinates, brightness, size, information on the central star and distance, plus relative intensities in key emission lines. Two-colour POSS images aid comparison, complemented by high-quality amateur photographs and the author’s drawings. Observing notes give minimum aperture and filter recommendations; some drawings were made with telescopes from 14 to 24 inches. Both a reference work and an illustrated volume, it is aimed at experienced deep-sky observers and readers with a strong interest in astronomy.
