Cartes du Ciel enables the user to draw sky charts, using the data in 16 catalogs of stars and nebulae. In addition the position of planets, asteroids and comets are shown.
The purpose of this program is to prepare different sky maps for a particular observation. A large number of parameters help you to choose specifically or automatically which catalogs to use, the colour and the dimension of stars and nebulae, the representation of planets, the display of labels and coordinate grids, the superposition of pictures, the condition of visibility and more.
All these features make this celestial atlas more complete than a conventional planetarium.
