Wes Warner, Imperial Star Destroyer (January theme: Weather)

This shelf cloud formed so quickly, I barely had time to set up my tripod and get my camera out of my bag. I had not been planning on taking any images and my SD card showed that I had about 17 images left. Every shot counted on this day.
