This image is a composite of Castle Rock from Moab and a night sky from Utah County, Utah. Castle Rock is a 400-foot Wingate Sandstone tower standing on a 1,000 foot Moenkopi-Chinle cone In Castle Valley, Utah about 20 miles east of Moab. 

The night my friends and I set up to take this shot it was cloudy and overcast. Ironically a thunderstorm shut us down for the night. The foreground was lit with artificial lighting. The night sky was replaced with one taken later in the year. The goal was to get a shot that would place the tail end of the Milky Way and Andromeda galaxy in the correct position, as if shot the original night. This incredible thunderstorm went through Utah on this night and I was fortunate enough to be on the southern edge. The blue light from the lightning was incredible.
