A couple of handy astronomy sites

A couple of sites I've found which are both good but both limited, but together allow a good grasp of the sky and its objects, and Stellarium shows the sky as seen. Mine is set to a Paris viewpoint, am still playing and haven't adjusted for Edinburgh. Celestia is not Earth-based. Space travel is possible!
