SkyMap produces highly accurate HP-GL output, which can be rendered (and color-manipulated) with PrintGLw/PrintGL. ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@satobs.org http://www2.satellite.eu.org/sat/seesat/seesatindex.html
