Many people seem to be using Rob Matson's Skymap to track satellites. I haven't used it yet, but I hope to quite soon. The quality must be pretty darn good, also because I've seen, we've seen, the other work he's done. I'm hoping it will display maps of various scales, because I hope to use it to show faint Vanguard's I haven't yet seen; and also be able to see planets at least around 50 degrees away. I need to be able to say things like "42 seconds later ISS will pass 27 degrees above the Moon". My question is "Do you have any other alternatives?". Has anyone used another program, available at some sort of reasonable value price, and Skymap; and decided that the other program is better? I don't know if Skymap is a planetarium program, but I'm basically thinking about a planetarium program with a satellite capability. I'll appreciate your opinions.

If tumbling rapidly enough, these are called flashers.
