Springtime star trails

Star trails

Forty-some min­utes worth of Earth­’s rota­tion. In the low­er-left cor­ner, you can watch the cres­cent moon and Venus set­ting; the moon is reflect­ed, a bit, in the water that was on the field.

Nerd stuff: 153 light frames, 5 dark frames; each frame is 15 sec­onds, f/2.8, 11mm, ISO 800.
