Abetti's "The Sun" has been recognized as the authoritative treatment on the subject since its first appearance in Italian in 1934. It was revised in 1951 and again in 1954. This is the first English version of that last edition, translated by J.B. Sidgwick. Light shelf wear to edges of boards. The jacket has a few small chips around the spine ends and a trace of sticker residue on the front near the upper right corner. Illustrated with many charts, diagrams, and black and white photos. Overall, a nice clean copy.
