The Other Night Sky

This is an ongoing project to track and photograph the world of secret satellites that are above our heads nearly constantly.

Although the satellites I track and photograph in this series are not typically acknowledged by the United States, they are cataloged and observed by an international network of amateur “satellite observers,” whose observations I use to calculate the position and timing of overhead transits.

To make the images, I use a wide range of cameras, telescopes and computer-guided mounts to achieve the positional and temporal accuracy that’s required.

For an insight into the kinds of work that amateur satellite-spotters do, take a look at the website of my friend Marco Langbroek.
