This program enables you to draw sky charts, making use of 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 permit you to choose specifically or
automatically which catalogs to use, the colour and dimension of stars
and nebulae, the representation of planets, the display of labels and
coordinate grids, the superimposition of pictures, the condition of
visibility and more.
These features make this celestial atlas more complete than a conventional planetarium.
