The rising Full "Wolf" Moon of January 6, 2023 over the Badlands of Horseshoe Canyon, near Drumheller, Alberta. The sequence demonstrates the changes in colour of the rising Moon from atmospheric absorption, and changes in its shape from atmospheric refraction.

This night the Moon was full almost at the same time as it rose from my location. However, the Moon's high northerly declination — it was about 4° north of the ecliptic — meant that it rose far to the northeast and some 30 minutes before the Sun set, despite the Moon being opposite the Sun. As such, even for the last shot, with the Moon several Moon diameters in altitude, the Sun was still up and lighting the landscape. In fact, at that time the Sun broke through clouds in the southwest to light the foreground with warm light.

In this blend, the ground and majority of the sky comes from the final image with the highest Moon and warmest landscape lighting. For the earlier shots the Moon came up in a very bright sky. And so, to better represent the scene, some of the sky coloration — the magentas and cyans — comes from earlier exposures blended in with broad-brush masks. Dark anti-crepuscular rays also added subtle sky colouration and bands of darker blue.

This is a sequence of 9 images at an interval of 2.5 minutes, extracted from a set of 80 frames taken every 15 seconds with the camera on automatic exposure, as the sky and ground remained bright enough for an accurate meter reading. The first 8 Moons are masked and layered in with a Lighten blend mode.

All images were the Canon R5 at ISO 125 and Canon RF100-400mm lens at 281mm and f/8. Most processing in Adobe Camera Raw with ground and sky masks. Glow and dynamic contrast filters added with ON1 Effects plug-in.
