My initial plan for this photographic expedition was to create a star trails image over the West Kennet Long Barrow while helping a friend image the Andromeda Galaxy with my Star Adventurer travel mount. An 86% waning gibbous Moon was due to rise at about the same time as the bonus event of the evening - a bright overhead ISS pass. I ditched the star trails plan and set about capturing the ISS instead. The image was photo-bombed by an airplane. I think that the airplane has actually added to the image and I was delighted when I saw that I had caught the intersection of the two flight paths. I love the juxtaposition of the Long Barrow, that was created around 3650 BC, and the busy hardware flying about planet Earth in 2018 AD. What would the people who built the Long Barrow make of our modern space flight?!
