A 22° around the Full Moon in a sky of high cirrus clouds and contrails. Shot with the 14mm lens and Canon 6D for 20 seconds at f/2.8 and ISO 400. The Moon sits above Orion in the winter sky. Orion is at bottom in the halo.
An ice crystal halo around the waxing quarter Moon, Dec. 1, 2014, taken from New Mexico. This is a 30-second exposure at f/2.8 with the 14mm lens and Canon 6D at ISO 400, with the bright area around the Moon itself masked and made from 3 shorter exposures to lower the intensity of the centre of the halo. The altitude of the Moon was 62° and the halo shows a split appearance on the east and west sides from what is called a circumscribed halo adding to the normal 22° halo.
