LE CIEL À L'OEIL NU, MOIS PAR MOIS

Extremely simple ephemerides to understand and use since they are aimed at neophytes and/or people who do not have instruments at all, or simply a pair of binoculars. The naked sky shows all the celestial phenomena not missing over a whole year, since January 1, with particular emphasis on the most spectacular events (e. g. eclipses). There are many very clear illustrations and schemas. A well designed practical book.
