Evening Stars Over the Red Deer River


Evening Stars Over Red Deer River

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.

Venus over the Atlas Coal Mine

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.

Time-Lapse – Alberta Skies 2013


 

It was a good year for time-lapse photography at home. Here’s my compilation of Alberta time-lapses in a 3-minute music video.

For a year-end look back at 2013 I assembled these highlights of my year of shooting time-lapse movies of the Alberta sky, by day and night. 

I’ve included clips shot around home in rural southern Alberta, and further afield at popular photo spots around the province such as Waterton Lakes National Park, Banff, Writing-on-Stone Provincial Park, and Cypress Hills Provincial Park. 

I hope you enjoy it! Be sure to maximize the video screen and select HD.  Or for a better grade version check out my Vimeo channel.

________________________________________________

Some technical background:

I shot all the frames for the movies (150 to 300 frames for each clip) with either a Canon 5D MkII or a Canon 60Da camera, equipped with various lenses from 8mm to 200mm. For many of the clips the cameras were on motion control devices: the Radian azimuth panning unit, an Orion TeleTrack mount, or a Dynamic Perception Stage Zero dolly unit. You see the latter in action behind the credits. 

For image processing and movie assembly I used Adobe Camera Raw, Photoshop, LRTimeLapse, Sequence, Panolapse/RawBlend utility, and for some of the star trails either StarStax or Star Circle Academy’s Advanced Stacker Actions.

I demonstrate all these in my Nightscapes workshops. The next one is in Edmonton, January 25!

To edit the movie I used the new OS10 Mavericks iMovie.

Coal Dust Stars


Star Trails over Atlas Coal Mine v2 (June 27, 2013)

The timeless stars turn above a long-abandoned coal mine near East Coulee, Alberta.

For decades, between 1912 and 1979, homes and trains were fueled by coal from the Atlas Coal Mine, one of many in the river valley near Drumheller, Alberta.

Thousands of mine workers populated the boom towns set in the badlands of the Red Deer River. The mines and most of the people are long gone. The Atlas Coal Mine was the last to close, holding out well into the current age of natural gas for home heating and diesel for the trains.

It’s the only mine with buildings that still exist, now as a tourist attraction with daily tours of the mine, both above and below ground.

I spent the evening there last night, the only visitor, except for the owls and coyotes. I was shooting time-lapse sequences and some stills. The shot above is a composite of twenty 1-minute exposures to create the star trails.

Big Dipper over Atlas Coal Mine (June 27, 2013)

For those who prefer a more realistic scene, the short-exposure image above captures the sky more as the eye saw it, with Arcturus and the stars of the Big Dipper shining above the massive wooden tipple.

The Drumheller area is rich in history and photo ops, both for day and night shooting.
