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.
The second Space Station pass of May 28/29, 2016, at 1:40 a.m., with cloud moving in adding the glows to all the stars. Taken with the 8mm fish-eye lens from home. The Big Dipper is high in the west at right. Mars is bright at bottom, to the south. Several other satellites are in the sky as well. This is a stack of 3 exposures, each 2.5-minutes with the camera on the Star Adventurer tracker.
