I sat in the dry grass with my calculator computing how many rotations we could get the telescope to make over 300 x 4-second intervals. Three and a bit, it turns out. The dish takes about 9 minutes to make a full rotation, and it takes me about 20 minutes to create a 12 second shot.
Surrounded by kangaroos and hares, I thought how lucky we are in Australia to have such a beautiful landscape and fresh air (and how lucky I was to have access to a piece of machinery the weight of 1.5 jumbo jets). Six telescopes line the 3km railway track with a fibre optic cable sending enormous amounts of data back to the server in a room insulated to prevent radio interference. Even mobile phones have to be switched off at the entrance to the property.
I’m also filming night time-lapse, but at 40 second intervals, will generate only 3.5 seconds of film every hour. Slow going. However, the star trails look astonishing with the milky way rotating past the dish’s upturned nose! I’m working at the end of the track, and it feels very remote. There’s no moon, no ambient light, just a countless array of stars above this enormous machine. Its motors grind away in the otherwise silent landscape. It slowly turns its face towards me and I can’t help feeling like it has a personality of its own.
The staff at the CSIRO have been great sports with all the filming and interviews.
During Daft Punk’s show, I went up in a light aircraft to shoot aerial shots of the dance floor. This was the best angle to see its design: a spinning record. However, looking through a lens with a moving horizon while doing constant 2g turns did make me chuck twice!
