It took some 20 shots to get one with a flash-lit model in it. Three flash guns used. Sometimes they didn't go off for some reason and it was tricky to get the model in the right place at the Right time. I wondered what that streak on the upper left was - it turns out it is the International Space Station passing overhead. That's a bit serendipitous isn't it?
Slightly boring video here. The annoying high pitched beeps are my flashes charging.
