A Faint Gegenschein by lrargerich on Flickr.

Look at the bright star near the left border of the photo: Spica. From a distance you will see a brightening around this star.

This brightening is the Gegenschein, sunlit scattered by interplanetary dust at the antisolar point.

The Gegenschein is really difficult to spot, you need a clear moonless night and the help of a camera, in my photo battling some light pollution it is faintly visible.

Knowing that the antisolar point was near Spica at the time the photo was taken helped a lot.
