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.
The bright and wide double syar, Beta Capricorni, a.k.a. Dabih, hangs on the leading limb of the crescent Moon, about to be hidden, or occulted by the Moon in a few minutes. This was Wednesday, November 26, 2014, shot from New Mexico. The dark side of the Moon is illuminated by Earthshine. This is a high dynamic range composite of 12 exposures from 4 seconds to 1/500 second, at ISO 400 with the Canon 60Da and through the TMB 92mm apo refractor at f/5.5 with the Hotech flattener. Images merged and tone-mapped in Photoshop HDR Pro and ACR.
