Tonight's Penumbral Lunar Eclipse wasn't very spectacular, but the halo that formed around the full moon was. I shot the halo and the full moon separately because they needed different settings. I then blended the two images so that both the moon and the halo would be in focus to reproduce what viewers could see with the naked eye.
Technically speaking, the circular image above is not really a halo. It is a weather phenomenon called a corona. A corona forms when high, thin clouds move across the front of the moon and the rays of light from the moon refract light from tiny water droplets or ice crystals in the clouds. A corona has the colors of the rainbow arranged in several concentric circles, while a true halo is a circle of white or light colored light around the moon.
