The dark blue band of Earth’s shadow on the atmosphere rising in the southeast, fringed with the pink Belt of Venus above, and with dark anti-crepuscular rays – cloud shadows - converging on the anti-Sun point. All over Reesor Lake in the Cypress Hills of southeast Alberta. At left, the white specks in the water are American pelicans. Shot as part of a 600-frame “holy grail” time-lapse sequence using the TimeLapse+ View bramping intervalometer. With 24mm Sigma Art lens and Nikon D750.
The waxing 7-day-old first quarter Moon at Reesor Lake in the Cypress Hills, shot July 30, 2017, as a demonstration image to illustrate the 90° angle between the Moon and sunset point, at right. It also illustrates the natural sky polarization darkening the sky 90° from the Sun. The Moon is just a little past first quarter and so is a little more than 90° from the Sun to the left of the polarization band. This is a single handheld image.
The Big Dipper and Ursa Major (at upper right), Arcturus (left of centre), and the waxing 6-day Moon (overexposed at left) in the deep twilight at Reesor Lake in the Cypress Hills, Alberta, July 29, 2017. The Big Dipper is slightly distorted by the wide-angle lens. This is a single 30-second exposure with the Rokinon 14mm SP lens at f/2.5 and Canon 6D at ISO 800.
