OK, some pics... These were both taken in the exact same spot, I positioned the bike by some marks on the road. I used this underpass to avoid any differences caused by the moon etc... Not ideal as the road curves up in the distance but you can see some results at least. I'm not sure there's really a perfect way to do this without better gear than I have.
