Star Trails over Mount Ouray
365: the 2015 Edition (235/365)
A half moon lit the sky on 8/23/15. I took a series of 18 exposures of 4 minutes each (total 1 hour and 16 minutes) and stacked them using StarStax. ISO 200, f/3.2, 16mm focal length.
If you compare this to the previous image in my photostream, you can see how many fewer stars can be seen when there's a half moon (this image) than when there's no moon (previous image).
