Sorry all for the lack of updates - I'm very busy with my day job at the moment! Never seem to be able to find the time to work on the app at the moment.
I'm getting reports that PlanetariaX doesn't run in the HTC Magic. I will look into this, but as I don't have this phone it's going to be a bit difficult to nail this problem down! Will upload a new version as soon as I've worked out what the problem is!
