I captured this image of the Zodiacal Light rising below the constellation Leo just before the crack of morning twilight. The zodiacal light is caused by dust in the plane of the solar system lit up by sunlight and is best viewed when the ecliptic stands as near vertically from the horizon as it can from your viewing location. The zodiacal light is the faint tall triangular shaped glow angling to the upper right. Also visible is a faint satellite silently orbiting Earth above. This view from Kitt Peak is to the south of the light cap above Tucson in the east-northeast which can be seen at bottom and brighter to the left. The Santa Rita Mountains are visible along the horizon at the lower right. This image was taken with my 24mm lens with an expsoure of 30 seconds at f/1.8, ISO 800.
