An excellent view of ATV Albert Einstein seen just moments after it separated from the ISS during the undocking procedure, 28 October 2013.

In the docking ring, you can clearly see an electrical connector, a fluidic connector, some of the hooks and a pusher – the mechanical thingy that actually gives ATV the first shove away from the Russian Service Module (click through for hi-res version in Flickr).
