Not sure if anyone is following Chris on Twitter, but I suggest you do. He takes some stunning (or is that great :P ) shots from the space station.
follow him on twitter - @Cmdr_Hadfield
Here is a link to some of his images
Here is a recent you tube of him explaining his gear, settings and how he goes about taking all those images.
EDit: just realised that Sifor posted the same video in a different thread yesterday.. sorry mate.
