A 3-section panorama of a retreating thunderstorm at sunset taken from my back yard, June 17, 2013, with the Canon 5D MkII and 14mm Samyang lens. The storm shows mammatiform clouds and virga from falling rain and a rainbow. The waxing quarter Moon is at right.
A bright bolide meteor breaking up as it enters the atmosphere and caught by chance at the beginning of a time-lapse sequence under the light of the Full Moon, April 25, 2013. Taken at the old farmstead near home, with the Canon 5D MkII and 24mm lens for 36 seconds at f/4 and ISO 800.
Comet PANSTARRS (C/2011 L4) over the VLA radio telescope array in New Mexico, March 17, 2013. The landscape is lit by the nearly quarter Moon high in the sky out of frame. This is a composite of two images taken moments apart: a 50-second untracked exposure for the ground and a 25-second tracked exposure for the sky, so both sky and ground are sharp. All at f/2.8 with the 50mm Sigma lens on the Canon 60Da at ISO 400. Position worked out with Photographers Ephemeris.
