23:00Dark. Overcast so no stars, but the ground is lighter as a result of light pollution reflecting off the clouds.The remaining camper van leaves the car park.
22:00Pink skies from the post-sunset light, while someone on the very top of the rock explains what can be seen in different directions.
24:00Sweep of lighthouse beams on the distant coast, car headlights sweep across the top of the Rocks.
01:00My god, it's full of stars!The cloud cover has shredded in the wind, exposing the Milky Way to view. Four hundred billion stars scramble for attention, utterly glorious.
03:00Are you up for it? Are you, mate?Yeah!Echoes and torch beams from the lower car park.
Midnight, the start of the 24 hour shoot.
02:00The heavens revolve above us, marking time, spiked on Polaris.Alternatively, the stars stay fixed and the Earth beneath us spins it's way through the void...
04:00Cars start to congregate in the car parks in the predawn light. Lines of people wind their way up the slope through the bracken, steeped in gloom.
