Jasper by Starlight


Taurus Rising over Mount Kerkeslin

The annual Dark Sky Festival in Jasper National Park ended with the best finale – dark skies, on a beautiful star-filled night. 

On Saturday night, October 22, I left the final set of science talks in the Big Tent at the heart of the Festival and headed out down the Icefields Parkway for a night of shooting Jasper by starlight.

The lead image is of the winter stars, including the Pleiades, rising above Mt. Kerkeslin at Athabasca Falls.

Pleiades and Taurus over Athabasca Falls
The Pleiades star cluster and the other stars of Taurus rising above Mount Kerkeslin at Athabasca Falls, in Jasper National Park, Alberta, October 22, 2016. The sky is brightening with the rising waning Moon off frame at left. Some cloud adds star glows and hazy patches to the sky. This is a stack of 15 exposures, mean combined to smooth noise, for the ground and one exposure for the sky. All are 25 seconds at f/2 with the Sigma 20mm Art lens and Nikon D750 at ISO 6400.

I shot the image above moments later, from the usual viewpoint overlooking the Falls, reduced to a trickle in late autumn. Illumination is solely by starlight – no artificial and glaring light painting here.

Perseus and Cassiopeia over Mt Kerkeslin
The autumn constellations of Perseus, Cassiopeia and Andromeda over Mount Kerkeslin at the Athabasca River Viewpoint on the Icefields Parkway, in Jasper National Park, Alberta. The Andromeda Galaxy is at upper right. The Pleiades are just clearing the mountain top at lower right. Thin clouds add the natural glows around the stars. Illumination is from starlight. This is a stack of 8 exposures, mean combined to smooth noise, for the ground and one exposure for the sky, all 25 seconds at f/2 with the Sigma 20mm lens and Nikon D750 at ISO 6400.

Earlier in the night, I stopped at the Athabasca River Viewpoint and shot the autumn stars of Cassiopeia, Andromeda, and Perseus above Mt. Kerkeslin. The Pleiades are just appearing above the mountain ridge.

Stars over Athabasca River
The autumn stars of the watery constellations of Capricornus, Aquarius, Piscis Austrinus, and Cetus over the Athabasca River and the peaks of the Continental Divide, from the Athabasca River Viewpoint (the “Goats and Glaciers” viewpoint) on the Icefields Parkway, Jasper National Park, Alberta. Thin cloud provides the natural glows around the stars. This is a stack of 8 exposures for the ground, mean combined to smooth noise, and one exposure for the sky, all 25 seconds at f/2 with the Sigma 20mm Art lens, and Nikon D750 at ISO 6400.

From that viewpoint I shot a scene looking south over the river and with the stars of Capricornus and Aquarius above the Divide.

Milky Way over Athabasca Pass
The Milky Way over the region of Athabasca Pass, as seen from the highway viewpoint on the Icefields Parkway, in Jasper National Park, Alberta, Oct 22, 2016. The Milky Way here is the section through Aquila, with Altair at top and Mars bright above the peaks of the Continental Divide. This is a stack of 8 exposures, mean combined to smooth noise, for the ground and one exposure for the sky, all 25 seconds at f/2 with the Sigma 20mm lens, and Nkion D750 at ISO 6400.

At the start of the night I stopped at the viewpoint for Athabasca Pass far in the distance. The summer Milky Way was setting over the pass. This historic pass was used by David Thompson in the late 1700s and early 1800s as his route into B.C. to extend the fur trade across the Divide. Thompson writes in his Journal about one particularly clear night on the pass:

“My men were not at their ease, yet when night came they admired the brilliancy of the Stars, and as one of them said, he thought he could almost touch them with his hand.”

The night ended with a display of Northern Lights over the Athabasca River. What a superb night under the stars in Jasper!

Aurora over Athabasca River
The Northern Lights over the Athabasca River in Jasper National Park, Alberta, Canada, on October 22/23 at about 1:30 am. I shot this from an access point to the Athabasca River by the bridge on Highway 93 on the Icefields Parkway. Pyramid Mountain is at left near the town of Jasper. Vega is the bright star at left; the Big Dipper is at right. The image is a stack of 10 exposures for the ground, mean combined to smooth noise and to smooth the water, and one exposure for the sky and aurora. All 15 seconds at ISO 1600 at f2 with the Sigma 20mm lens and Nikon D750.

As a finale, here’s a music video collecting together still images and time-lapse movies shot this night, and on two other nights during the Dark Sky Festival, including at the big Lake Annette “Beyond the Stars” star party I spoke at.

Enjoy!

As usual, enlarge to full screen and go to HD for the best view.

Thanks!

Celebrating Dark Skies in Jasper, Alberta


Milky Way over Lake Annette

This weekend Jasper National Park in Alberta, Canada celebrates the night sky at its annual Dark Sky Festival.

Last night was wonderful. Skies cleared at Lake Annette for a star party with 1000 people in attendance. The event was a core program of a week-long Festival celebrating Jasper National Park’s status as a Dark Sky Preserve.

The top photo shows what we’re celebrating – the stars and Milky Way reflected in the still waters of Lake Annette. What you don’t see in that image are the hundreds of people behind me enjoying the star party.

Lake Annette Star Party #1

I’m one of the featured guest speakers, though last night my role at the star party was to assist at informal tutorials to help people take their own night sky images. And lots of people showed up with cameras and tripods and got great shots.

While I was not able to make the rounds of all the activities, elsewhere at Lake Annette (just follow the coloured rope lights!) there were talks, First Nations performances and storytelling, laser tours of the sky, activities for kids, and lots of telescopes to look through. Everyone got to see amazing sights in the sky.

Shuttle buses from town came and went through the night, to avoid a parking lot jam. The Festival is a huge hit, with hotels in town filled – there isn’t a room available.

The event went very well, at what was perhaps Canada’s largest public star party ever held under dark skies.

Pre-Eclipse Day in Jasper


Sunbeams over Athabasca Pass

It’s the day before the eclipse, and the skies are not clear!

On Thursday, October 23 the Moon covers the Sun in a substantial partial eclipse. I’m in Jasper National Park, participating in the Park’s annual Dark Sky Festival.

One of the events is a public viewing session of the solar eclipse. Let’s hope for some clearing skies and breaks in the clouds, so we can see 66% of the Sun eaten by the Moon!

I shot this image at eclipse time the day before – today! – from a viewpoint looking west toward the Sun on the Icefields Parkway south of Jasper townsite.

David Thompson Sign at Athabasca Pass Overlook

The Sun is trying to break through and is casting its beams down onto the famed Athabasca Pass, the route over the mountains pioneered by David Thompson in the early 1800s when his preferred route over Howse Pass to the south was blocked by the Pikanii who objected to Thompson trading with their enemies over the Rockies.

I show the area of Howse Pass in this previous big post from earlier this summer

Thompson was one of the first astronomers in western Canada, using the Sun, Moon, Jupiter and stars to navigate his way and map the country. The lower sign explains. Click on the image for a larger view.

The Dark Sky Festival continues the tradition of stargazing in Jasper, a science Thompson depended upon in his travels.
