Polar Windmill

The windmill, once a common but neglected artifact of an earlier technology, has become as rare as the clear dark nights of their time. This one had survived, and was functioning, and on this night was conveniently aimed to catch an east wind that had no breath. I found the spot where Polaris could be centered in the view through the stalled blades, an awkward angle at this latitude. The exposure was timed to be exactly 80 minutes, the time for the Earth to rotate 1/18 of a full circle, the angular separation between this windmill's 18 blades.
