Riassunto:

The English edition of Roth's celebrated handbook has been considerably revised and enlarged. In three volumes the tools needed by practical astronomers are presented in this unique presentation by outstanding experts. The work addresses both the amateur stargazer and students and teachers in high schools and colleges.
