It is now possible to generate and add a local horizon to star charts. Originally, this was only supposed to be kind of a "service release", but it turned out to be more work than foreseen: I hadn't thought about the fact that a horizon should remain horizontal even when rotating the viewing direction - as the name already suggests ;-) Until now the display was always automatically oriented so that the celestial north pole was "upwards"; now this can be set to be an arbitrary point, and for horizon displays this is set to be the zenith. On the homepage an example for this new function is shown. The rest of the examples is replaced by the ones shown at Warpstock Europe in Karlsruhe/Germany (13-15 Oct 2000). This also "blew up" the online docs a few 100kb: They too include now the same, illustrated examples.
