A photo of a colorful Colorado sunset I took some years ago from the bluffs behind my old townhouse. 

The townhouse complex was built around a series of bluffs in the neighborhood. I use to do some imaging from the bluffs at night, including of star trails and a lunar eclipse. It was also a great spot to get sunset shots like this because it provided such good views of the sky. 

This was taken with a Canon 70D and a Tokina 11-16mm f/2.8 AT-X116 Pro DX lens.
