For use with Linux, Windows, macOS
This program enables you to draw sky charts, making use of the data in many 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.
The software itself is released under the GPL license.
You are free to use any chart or print produced by the program for any use, commercial or not (blog, web publication, printed book,…). You can mention Skychart and link to this page, but this is not required.
You can help the project in different way, no need to be a programmer.
