If you’ve never seen a tele-video of a distant terrestrial scene silhouetted by a rising moon, look at==> http://vimeo.com/58385453.
The casual observer often complains that this must be a manipulated photoshop type trick.
It is an interesting exercise for students to investigate this by calculating, and comparing, the speeds of the terrestrial and lunar images across the camera film/digital sensor.
More than sufficient data is available from the video clip, its commentary, and known lunar data.
