      Thanks for sharing those, Laurence. The NLCs look as if they illuminate the whole scene. I wonder if they can be so bright that objects on the ground cast shadows from their light?

      I think the answer to your query, Noctilucy, is that the photo was taken via a long exposure using a small aperture giving rise to the objects etc casting  shadows over a period of quite small time

      PS I much like your pen-name, “Noctilucy”.
