WILDLIFE PHOTOGRAPHY – ASTROPHOTOGRAPHY
This photograph of the moon was taken on February 15th, 2011 and was a couple of days before the full lunar phase. The camera gear used was a Nikon d90 attached to a Phoenix 650mm lens mounted on a tripod.
The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. The Moon spends the extra 2.2 days “catching up” because Earth travels about 45 million miles around the Sun during the time the Moon completes one orbit around Earth.
