Mars, at right, reflected in Emerald Lake at twilight in Yoho National Park, BC, June 7, 2016. Cathedral Peak is to the left, and the lights from some of the Lodge buildings. Mars was near its brightest for the year, indeed brightest in a decade at this time and prominent as a red object low in the south at twilight. This is a single 6-second exposure at f/3.2 with the 20mm lens and Nikon D750 at ISO 100.
