An overhead pass of the ISS on October 5, 2017, with the Full Moon rising in the east at left. The ISS is moving from west (at right) to east (at left), passing nearly overhead at the zenith at centre. North is at the top, south at bottom in this fish-eye lens image with an 8mm Sigma fish-eye lens on the Canon 6D MkII camera. This is a stack of 56 exposures, each 4 seconds long at an interval of 1 second. The increasing apparent speed of the ISS against the background sky as the ISS approaches from the distance out of the west, then decreases as it flies away to the east, creates the dashed trails of different lengths reflecting its change in apparent speed against the star field. The ISS is much closer to us when it is overhead than when it is near the horizon. At left, the ISS fades to deep red as it enters Earth’s shadow. The stars are trailed over the few minutes of exposures, moving in concentric arcs around Polaris at top. Taken from home in southern Alberta.
