Stuff like this is reassuring - all the bullshit in little corners of this small blue marble of ours really doesn't matter very much.

As the earth rotates, there is a point in the sky where the stars seem to spin around, one full rotation every 24 hours. This is known as the North Celestial Pole for people in Europe, US and Canada, and the South Celestial Pole for us who live in Australia. It mid-winter here, and the winter solstice, the longest night of the year, was a few days ago. Fortunately it was a clear night, with a setting moon.

I pointed my camera at the South Celestial Pole, and programmed it to take a photo every 15 minutes for 7 hours. I had a lens warmer on to prevent fogging and frost on my glass, and an external battery so the camera could do its thing all night.

I went to bed and collected the camera the next day. I stacked all the shots to create a single image.

Tech details for those who are interested: Sony A7RV, Laowa 15mm lens, f/2.8, ISO 400, 2 min exposures, stacked in Affinity Photo.
