The science behind the photo that put a hurler on the moon

Putting a hurler on the moon, as photographer James Crombie succeeded in doing on Tuesday night, involved a great deal more than a trained eye and quick finger.
Having tossed around in his head for 10 years the idea of capturing this image, Crombie, a couple of weeks back, enlisted the help of his geophysicist friend, Colin Hogg, to map out where exactly he would shoot and where exactly the shot would be taken from.
