I've used Nasa shots for wallpaper before, besides grant's link above, there's this jet propulsion lab site, as well.
I think it would be difficult to take good shots of night skies without some good equipment, but I've never tried. I know many consumer model telescopes have fittings for cameras, but that's a bit pricey. Maybe when the cold, clear air comes in soon, I'll give it a shot and post here. There's not much light pollution here, might make something visible, anyway. |
