I'm just wondering, World Wide Telescope has a great sky map, is there a way to add this to my Windows 8 Store app? I have no experience with DIrectX which is why a prebuilt sky map API would be really useful.
The license for WWT (because of the nature of the data we provide) is for non-commercial use. You could put it into a free App Store app designed for educators, but not something you charge for.
