Check this out. There is a Flickr group that you can post photos of the night sky to. They run your photo through a "solver" and it labels the objects in your photo. I used a Canon SD700 IS camera, set the shutter speed at 15 seconds while shooting off a tripod pointed at the night sky. Kinda like a custom star chart.
Here is the site:
