It can accurately simulate the sky as it appears tonight, as well as hundreds or thousands of years in the past or future. You can view the heavens from any place on earth, or from any object in the solar system and beyond it. Highly detailed, high precision, nice feature exporting charts to .bmp format. Stars, planets, user definable objects, animation. Shareware version does not contain deep sky objects, but give the impression that registered version would be an very nice program.
Registered version is very inexpensive.
This program contains information about the planets in our solar system and some Messier-objects. There are also many pictures included. So if you want such a sky simulation program try others, e.g. SkyMap or SkyGlobe. It is also available as a German Version. But this program is Shareware, so if you'd like to use it regularly please pay the registration fee.
