Old radar instillation.
This photo was taken at night. The dashes show you how far stars "travel" across the sky (due to Earth's rotation) in 11 minutes. I must have been looking northeast: If you determine where the center of rotation is (just to the left of the lower portion of the photo), that is where the North Star would be.
There is a single light about a block away and behind me. Brush and other obstacles shield the lower portion of this tower from the light. Even though it is a single light and is that far away, over an 11-minute exposure it is enough light to illuminate all the rust of this fascinating monstrosity.
