Night Sky Live is an interesting website that chronicles the efforts of a group whose goal "is to create a useful continuous record of the night sky". The worldwide system is built around small fisheye lens cameras that are controlled by laptop computers and deployed at major observatories around the world.
This image above is a screen shot from their web site; each colored asterisk represents the location of a camera; each serves as a link leading to a page with images from the camera. Below is a sample image from the Kitt Peak camera.
Many nights, due to fog, light from the moon or just generally poor "seeing", the images are of somewhat less quality than one might hope. The image gallery has a number of particularly interesting images, including meter and satellite tracks, lunar eclipses and more.
