It was filmed by a friend of mine and edited by him and myself, the tractor was edited in the film after. It was uploaded onto my site and I wanted to share it.
there cant be cloud cover and the moon cant be out when filming, we were filming as well as taking photos at the same time with the same camera, i wasnt really too involved with the settings or camera set up, my friend is an astrophotographer who was setting up and filming, we did it in (15) 20 minute intervals through out the night and the spliced it together. I guess we cheated a little bit, but i have never heard of doing it any other way.
