Telephoto Moonrise


This telephoto shot emphasizes the color difference between the just-risen full moon and the surrounding twilight sky. The sky is cloud-free and a rich dark blue in the deepening twilight. But we are looking through so much atmosphere (the moon is less than 1 degree above the horizon) that even the slightest amount of airborn dust colors the moon a beautiful pink. Also noticeable is a slight "flattening" of the moon due to atmospheric refraction. Taken 19 minutes after sunset, looking east-southeast over the city lights of suburban Phoenix, Arizona.
