Still using Win95/98/Me? Version 3 as some limitation on this systems. The old version 2.76 that run only with Windows is still available [[http://astrosurf.com/astropc/oldversion/cartes/telecharg.html|here]] but no more maintained. 


====== Description: ======
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 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.
