Thanks for adding a link to my orrery program. It is nowhere near as beautiful as stellarium, but I'm having fun working on it. I'd very much appreciate it if people would give it a try and send me suggestions for improvements, either through its Bugzilla database, or just by mailing me at orrery.moko@gmail.com. One minor thing orrery has going for it is that it was originally written for Openmoko Freerunner phones, which have about 1/20 (really!) of the processing power of an N900. So I had to work hard to make the calculations run efficiently, or else it would have been unusable on a Freerunner. On an N900, it is quite responsive. It still needs a lot of "hildonizing" to fit in well with other Maemo 5 apps. Documentation for the program can be found here: http://wiki.maemo.org/Orrery Thanks again!
