A gathering of planets in the dawn sky on October 8, 2015, with - from bottom to top: Jupiter, Mars, Venus and the Moon, with the star Regulus in Leo left of Venus. This is a 15-second exposure with shorter exposure blended in for the area around Venus and the Moon to avoid them overexposing too much. So not a true HDR, but using masking to blend the short exposure elements.
The Full Moon in total eclipse in the deep evening twilight over Writing-on-Stone Provincial Park, in southern Alberta, on September 27, 2015. This is a single exposure taken as part of a 730-frame time-lapse sequence. Exposure was 5 seconds at f/2.8 with the 35mm lens and Canon 6D at ISO 800.
