March star trails

This past Sat­ur­day, the sky was clear and the auro­ral fore­cast looked promis­ing, so I drove out to a dark spot to check out out. The auro­ra, if it was there at all, was a very faint smear at the extreme north­ern hori­zon. But I had bought a cof­fee, so I stuck around long enough to get some star trails.

The pho­to is about 150 images, 10 sec­onds each, ISO 800, f/2.8, 11mm, all stacked in GIMP. The wax­ing half-moon lit the fore­ground for me.
