After Niki Giada’s photo of the Sun’s halo, here we are again with another impressive astrophoto. This time, it’s the Moon’s halo.
Earl Matenga captured this photo of the Moon and its halo on March 25, 2010 using a Pentax K-7.
Moon halos are brought about by the same phenomenon as Sun halos are. It’s caused by the refraction of light from tiny hexagonal ice crystals in the atmosphere.
This photo was shot through a Pentax fish eye lens mounted on tripod, bulb setting 2-3 sec exposure remotely fired. The red star on the left is Betelgeuse which is located in the constellation of Orion.
