Taken on February 20, five different exposures made in rapid succession were used to created this tantalizing telephoto image. In combination, they reveal a wide range of brightness visible to the eye on that frigid evening, from the urban glow of the Quebec City skyline to the triple conjunction of Moon, Venus and Mars. Shortly after sunset the young Moon shows off its bright crescent next to brilliant Venus. Fainter Mars is near the top of the frame. Though details in the Moon’s sunlit crescent are washed out, features on the dark, shadowed part of the lunar disk are remarkably clear. Still lacking city lights the lunar night is illuminated solely by earthshine, light reflected from the sunlit side of planet Earth.

於2月20日，快速連拍的五張不同曝光照片製作出這幅誘人的長焦成像。這些圖像結合起來，展現了在那個寒冷之夜可見的廣泛亮度範圍，從魁北克市天際線的城市光芒到月亮、金星和火星的三重會合。日落後不久，年輕的月亮與明亮的金星並排顯示出其明亮的弦月。較暗的火星位於畫面的頂部。儘管月亮的日照弦月上的細節被洗淡，但陰影部分的特徵卻異常清晰。此時月球夜晚尚未受到城市燈光影響，僅由地球光照亮，即從地球的日照面反射回來的光線。
