Mercury and Venus shine as “evening stars” over the Red Deer River in southern Alberta.
What a fine night this was for nightscape shooting. Mercury and Venus are both now about as high as they will get for the year in the evening sky from my western Canadian latitude.
Venus is easy to spot as the brilliant object in the west. But Mercury is more elusive. You can see it here low in the twilight glow and much dimmer than Venus.
The photo illustrates how far each of the two inner planets swings away from the Sun in our skies, and why Mercury has its reputation for being difficult to sight. Also, it appears at its best for only a couple of weeks at a time. By mid-May it will be gone.
Venus, however, continues to dominate our western sky for the next two months.
I shot the main photo from the deck of a rickety wooden bridge over the Red Deer River near Dorothy, Alberta, just off Highway 10 east of Drumheller in the Badlands.
The image is a high-dynamic-range “HDR” stack of five exposures.
Shortly after taking the lead photo, I drove west to the Atlas Coal Mine to shoot it by the light of the now high and nearly Full Moon. Mercury can still be seen low and to the right of the historic tipple building. Venus shines above it.
This is a single 25-second exposure at ISO 800.
The Atlas Coal Mine is now a National Historic Site and is the last standing from what was once a booming coal mining centre in the Red Deer River Valley.
Now, mostly dinosaur fossils are unearthed here.
