Venus and Stars Setting over Calgary.jpg
Venus (the brightest object above Banker’s Hall and just in cloud), and the last of the winter stars (Castor & Pollux above Venus, and Capella at right) sinking into the west and northwest on a late May evening.
This was from Scotsman’s Hill overlooking the Stampede Grounds. It was taken as a demonstration of using a graduated neutral density filter to dim the city lights while leaving the sky more or less untouched and unfiltered, to better balance the huge difference in brightness between the natural sky and unnatural ground.
Taken with the Sony a7III at ISO 100 and Canon 24mm lens, at f/4 for a single exposure of 15 seconds. Using a Cokin P Grad Filter “upside down” so the dark area was at the bottom. No light pollution filter was employed. The diffraction spikes are from the lens iris, not a filter.
