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.
Evening twilight reflections in blue at Emerald Lake, Yoho National Park, BC. This is a single 3-second exposure at f/5.6 with the 20mm lens and Nikon D750. I used an indoor white balance here to enhance the blue.
The Big Dipper (left), Polaris and the Little Dipper (centre top), and Cassiopeia (right) over Emerald Lake, Yoho National Park, BC. Lights from Emerald Lake Lodge illuminate the trees. The light from perpetual summer twilight lights the sky deep blue. In early June the sky never gets completely dark at this latitude. This was June 6, 2016. This is a stack of 4 x 40 second exposures for the ground (mean combined to smooth noise) plus a single 40-second untracked exposure for the sky, all at f/2.8 with the Rokinon 14mm lens and Canon 6D at ISO 4000.
