Help I have been talking to a guy at southern stars about the skychart program. http://www.southernstars.com/skychart/index.html It allows for showing the passage of satellite across the moon and background stars. I had problems with it not showing the satellites in the correct location before. But now they have improved the program in it's calculations of satellite positions. There is still a slight problem with it showing the position of the satellites. Here is the problem I like to watch satellites going across the disk of the moon. I use rob's skymap to see where on the moon they will go across and then watch in my telescope. But I would like to do that also with skycharts. So can my fellow satellite observers who use skymap give us a hand in trying to fix what might be a problem with skycharts, or either me. I find rob's skymap and the windows skymap at http://www.skymap.com , agree in the path across the moon. But skycharts is slightly off. Call me fussy, so be it. I find in both skymaps, the satellite goes across the unlit area of the moon, but in skycharts it doesn't, so what I am doing wrong, it must be my fault:) Check to see what positions you get for the satellite and moon, in skycharts and rob's skymap. I find I get different positions, which would because I would think, by the way the programs calculate the info. You will need to download the demo version, then download a patch to use the improved method of getting satellite positions using the improved SGP4/SDP4 orbital model from my site. It is not on the skycharts site, as we are bug testing it before it goes there. http://ca.geocities.com/kfetter/SkyChartIIIDemo.zip Thanks for all the help you can give.
