Here is one of quite rare celestial "objects" which doesn't appear on images often - the Gegenschein. Gegenschein is a faint brightening of the night sky in the region of the antisolar point. Physically, the gegenschein is sunlight backscattered by interplanetary dust. (http://en.wikipedia.org/wiki/Gegenschein). Usually its seen under very good and dark skies only. Here is the image from the north of Chile, where we witnessed the Gegenschein in early November this year.
Thanks, guys ! I used my standard setup - Canon 6D + Nikkor 14-24. The Gegenschein requires truly dark skies, because it's quite faint and the contrast is low. Some luck is needed, but it's not impossible for sure.
