L'observation du ciel - À l'oeil nu, aux jumelles ou au télescope

⚠️ This book is written in French.

This guide presents a chapter for each month of the year. It is easily accessible to any observer wishing to learn to recognize and identify constellations, star clusters, nebulae, galaxies and meteor showers, or even to follow the movement of the planets. Moreover, all the targeted celestial objects are visible with binoculars or small telescopes, and most are even visible to the naked eye.
