Star trails in full moonlight at the Wichita Mountains Wildlife Refuge in southwest Oklahoma. Should've waited for a completely clear night, but I was impatient to get out again after a full week of no storm chases.
This is 88x30 sec. exposures (44 min. total) at f/3.5, ISO 400. Stacked using the excellent (and free) Startrails software.
Fun fact: I walked out into the tallgrass a ways from the road to set up this shot, and since I hadn't seen hardly any traffic on the main road through the Refuge (much less any cars stopping at pullouts), I got the crazy idea that I could just leave my tripod set up there with the remote shutter release locked in and go scout out the next spot for trails. So I drove about 30 miles round-trip during the course of this shot while my camera sat here snapping away all on its own, undisturbed. Digital makes life too easy, eh?
