Ditto with Voyager v4.5 from CarinaSoft in Canada - which I personally prefer to Starry Night Pro by a large margin. Again, it's pay-for, at about US$180 but worth every penny. I've actually uninstalled all other planetarium software - including Starry Night. This does everything I want without SN's extra bulk which is quite frankly...uhmmm dead weight.
The SN interface is still a little "slicker" and prettier, but I prefer the starfields and map projections generated by Voyager once tuned to my preferences. They are both immensley powerful offerings, amd I think that it probably comes down to symantics when trying decide between the two. I just get the feeling that Starry Night's coders spent way too much time on candy and forgot the main mission. That's only my own subjective opinion, mind.
Voyager is a 4.5Gb install. This software has been steadily developed since 1987. Says it all. Windows (Vista, absolutely wonderful), MacOSX and now iPhone apparently.
