Star trails from within the rock formations at the Paint Mines Open Space in Calhan, Colorado, a series of colorful rock formations located about 45 minutes east of Colorado Springs. 

This shot consists of one light-painted photo of the foreground to illuminate the rock formations and highlight their distinct colors, and more than 100 long exposure shots of the sky to produce the trailing effect of the stars. 

I took this with a Canon 70D and a Rokinon HD8M-C 8mm f/3.5 HD fisheye lens. Rebekah handled the light painting, moving the beam of a flashlight across the rock formations while I took a long exposure image.
