A Stunning Gathering of Worlds


The conjunction of Venus (brightest), Jupiter (above Venus) and Mars (dimmer below Venus & Jupiter) looking east in the morning twilight on October 25, 2015, as seen from the west shore of Lake Annette, in Jasper National Park, Alberta. The mountain is the Watchtower. Morning mist covers the lake waters. Haze in the sky adds the natural glows around the planets — no filters were empolyed here. This is a layered stack of 4 images: 10, 5, 2.5 and 1.3-second exposures, with the longer exposure for the ground and the shorter exposures adding the sky to maintain tonal balance between the dark ground and bright sky. All with the 24mm lens and Canon 6D at ISO 400. It was not possible to capture the reflection of the planets in the water as they were too high in the sky.

Skies were clear at dawn this morning for a fabulous view of the rare conjunction of three planets. And I could not have been at a more photogenic site.

This was the view before dawn on October 25, as brilliant Venus and dimmer Jupiter shone just a degree apart in the dawn sky. Mars, much fainter, shines just below the close duo. The three planets could easily be contained in a high power binocular field.

Not until November 2111 will these three planets be this close together again in a darkened sky.

Indeed, Venus could not have been higher, as it is just now reaching its maximum elongation from the Sun, placing it high in the eastern morning sky.

A panorama of roughly 120° showing a star- and planet-filled sky in the dawn twilight over Lake Annette in Jasper National Park, Alberta, on the morning of October 25, 2015.  At left, to the east, are the two bright planets, Venus (brightest) and Jupiter in a close conjunction 1° apart (and here almost merging into one glow), plus reddish Mars below them, all in Leo, with the bright star Regulus above them. Right of centre, to the south, is Orion and Canis Major, with the bright star Sirius low in the south. At upper right are the stars of Taurus, including Aldebaran and the Hyades star cluster. Venus was near greatest elongation on this morning.  No special filter was employed here — the hazy planets and stars and colourful star images comes naturally from a high haze over the sky this morning. It bloats the images of Venus and Jupiter so they almost merge.  The stars are partly reflected in the waters, with rising mist in the distance on the lake. Distant Whistler peak below Orion is lit by lights from the Jasper Townsite. The site is the shore of Lake Annette near the Jasper Park Lodge and site of the annual star party held as part of the Jasper Dark Sky Festival. I shot this scene the morning after the 2015 Festival. This is a panorama of 8 segments, shot with the 24mm lens mounted vertically (portrait), each for 25 seconds at f/2.8 with the Canon 6D at ISO 3200. Stitched with Photoshop, with some vertical scaling to reduce the distortion introduced by the pan mapping process.

I shot from the shores of Lake Annette, site of one of the major events, the Friday star party, at the annual Jasper Dark Sky Festival which just concluded, in Jasper National Park, Alberta. The Festival celebrates the Park’s status as one of the world’s largest Dark Sky Preserves.

The hotels and restaurants were full with stargazers from around the world, making the Festival a huge success, both educationally and financially. I was honoured to be able to present some of the public and school talks.

But this dawn sky was a fine way to end a fabulous weekend of astronomy.

The image above is a panorama in the twilight, sweeping from the planets in the east, to the winter stars and constellations, including iconic Orion, in the south and southwest.

A panorama of roughly 180° showing a star- and planet-filled sky in the pre-dawn hours over Lake Annette in Jasper National Park, Alberta, on the morning of October 25, 2015.  At left, to the east, are the two bright planets, Venus (brightest) and Jupiter in a close conjunction 1° apart (and here almost merging into one glow), plus reddish Mars below them, all in Leo, with the bright star Regulus above them. At centre, to the south, is Orion and Canis Major, with the bright star Sirius low in the south. At upper right are the stars of Taurus, including Aldebaran and the Pleiades star cluster. Venus was near greatest elongation on this morning.  The Milky Way runs vertically at centre, between Sirius and Procyon, the bright star above centre. The faint glow of morning Zodiacal Light rises in a diagonal band at left in the east through the planets and stars of Leo and into Cancer and the Beehive Cluster at top left.  No special filter was employed here — the hazy planets and stars and colourful star images comes naturally from a high haze over the sky this morning. It bloats the images of Venus and Jupiter so they almost merge.  The stars are partly reflected in the waters with wind distorting some of the reflections. Some green airglow appears in the south as well. Distant Whistler peak below Orion is lit by lights from the Jasper Townsite. The site is the shore of Lake Annette near the Jasper Park Lodge and site to the annual star party held as part of the Jasper Dark Sky Festival. I shot this scene the morning after the 2015 Festival. This is a panorama of 12 segments, shot with the 24mm lens mounted vertically (portrait), each for 30 seconds at f/2.8 with the Canon 6D at ISO 3200. Stitched with Photoshop, with some vertical scaling to reduce the distortion introduced by the pan mapping process.

Earlier in the morning, before twilight began to brighten the sky, I shot another even wider panorama from the south shore of the lake.

In this and other photos, high haze adds the glows around the stars and planets naturally. No special effects filters here!

But Venus and Jupiter are so close and bright their images almost merge into one glow.

Brilliant Venus, in conjunction with dimmer Jupiter above, and with even dimmer Mars below, at left here, on the morning of October 25, 2015 when Venus and Jupiter were only 1° apart.  I shot this from Lake Annette in Jasper National Park before the sky started to brighten with dawn twilight. High haze in the sky adds the glows around the stars and planets, in particular the colored halo around Venus. The mountain is the Watchtower. The site is used as the main star party location for the annual Jasper Dark Sky Festival. This is a 30-second exposure at f/2.8 with the 35mm lens and as ISO 1600 with the Canon 6D.

Here they are, with Mars below, shining in the dark sky over the Watchtower peak and over the misty waters of Lake Annette.

Keep an eye on the sky at dawn, as these three worlds will be close to each other for the next few mornings. See my earlier blog for details.

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.

The Partial Solar Eclipse from Jasper, Alberta


Partial Solar Eclipse in Cloud #1 (Oct 23, 2014)

A successful solar eclipse! Always a great thing to celebrate!

Today, several hundred people, including students from the nearby elementary and high schools, enjoyed views of the Moon eclipsing the Sun from Jasper, Alberta. The eclipse event in Centennial Park was part of the Park’s annual Dark Sky Festival, held to celebrate the National Park’s status as a Dark Sky Preserve.

The photo above is a long 1/25 second exposure, though still taken through a solar filter, of the eclipsed Sun dimmed by clouds. The longer exposure enabled me to pick up the clouds and iridescent colours around the Sun.

The photo below is a single exposure capturing the viewing through the many telescopes supplied by volunteers from the Royal Astronomical Society of Canada (Edmonton and Regina Centres), as well as capturing the crescent Sun, seen here though a handheld solar filter.

Partial Solar Eclipse Wide-Angle (Oct 23, 2014)

Clouds came and went over the afternoon, but when they needed to be gone, clouds cleared off around the Sun for great views of the Moon hiding then revealing the giant sunspot that was the highlight of this eclipse.

The image below, which I shot through a small telescope at 1/8000th second through a filter, shows the big spot group about to be hidden by the advancing limb of the Moon.

Partial Solar Eclipse & Sunspot #1 (Oct 23, 2014)

This event was our last solar eclipse visible from most of Canada until the long-awaited “Great American Eclipse” of August 21, 2017, when the lunar umbral shadow will sweep across the United States, bringing a total eclipse to the U.S. and a substantial partial eclipse to Canada.

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.

Milky Way Over the Icefields


Milky Way Over the Icefields

The Milky Way towers over the moonlit peaks around the Columbia Icefields

Last Sunday was a productive night, resulting in several 5 Star images in my catalog!

This is another, shot shortly after the Galaxy and Glacier image. In that image the sky was still dark. In this image the sky is beginning to light up with moonlight from the rising waxing Moon.

The peaks are being lit by the Moon, though the valley below is still in moonshadow.

What light there is on the foreground moraines is from starlight, and from the unfortunate wash from unshielded sodium vapour lights on the Icefields Centre. They proudly claim their lights are dark-sky friendly. They aren’t! This is proof.

The top image is a stack of tracked (for the sky) and untracked (for the ground) exposures to create a deep, rich Milky Way over a sharp landscape.

The image is helped by being shot with a filter-modified camera that records the red nebulas along the Milky Way better than stock cameras. That’s why the North America Nebula at top in Cygnus really pops!

Icefields at Moonrise Panorama

This 360° panorama image is a stitch of 8 segments at 45° spacings, each untracked, shot in rapid succession with the same 15mm ultra-wide lens I used for the main image, again oriented portrait, with the frames stitched in PTGui.

I shot it on the road, literally, that leads down to the toe of Athabasca Glacier.

I took the pan just after the image at top, so the peaks are lit more and the sky is bluer with moonlight. The Moon itself is still behind the mountains to the left (east) about to clear the ridge moments after I finished this pan. It was a busy night of getting shots timed right!

But waning Moon nights are superb for nightscape imaging as they provide both dark and moonlit skies but without the immense light of a Full Moon that tends to wash out the sky too much. Waning Moon nights are great for shooting landscape features to the west, as they get lit by the rising Moon after midnight.

P.S.: A tip – hit “Tips and Techniques” under Category at left for more blogs with tips and techniques!

Andromeda over Mt. Andromeda


Andromeda over Mt. Andromeda #2

The stars of Andromeda and the autumn sky shine over Mount Andromeda.

This is a photo I’ve been after for several years, one practical to take only in early autumn. Last Sunday night, the skies were ideal.

This is the constellation of Andromeda over its namesake peak, Mt. Andromeda, at right.

The mountain was named in the 1930s by pioneering mountaineer Rex Gibson for the mythological princess. Andromeda is represented in the sky by an arc of stars, here at top centre, stretching from the Square of Pegasus, at right of centre, to Perseus, at left. Just above the main stars of Andromeda lies the oval glow of the Andromeda Galaxy.

The bright object at lower left is the overexposed waning quarter Moon rising in the southeast. Above it are the Pleiades rising.

I shot this from the Forefield Trail just up from the parking lot for the Toe of the Glacier walk to Athabasca Glacier, just off frame to the right. The hills in the foreground are the lateral moraines from the rapidly retreating glacier.

P.S. This my 500th blog post, a major milestone I would think! Thanks for being a fan and reading along. I hope you are enjoying my tours of what is truly an amazing sky.

Galaxy and Glacier


Milky Way over Athabasca Glacier

The centre of the Milky Way Galaxy sets behind the Athabasca Glacier and Columbia Icefields. 

This was one of the clearest nights I have ever seen at the Icefields. Unlike most nights, last night not a whiff of high cirrus was wafting off the great sheets of ice in Jasper National Park, leaving the sky pristine for the Milky Way to shine over the glaciers.

I shot this image Sunday night, September 14, from the approach road down to the tongue of the Athabasca Glacier. At this time of year, the Milky Way sets directly behind the glacier in the early evening. The angles were perfect.

At left is the glacier-clad peak of Mt. Andromeda, indeed named for the constellation and mythological princess. It is lit just by starlight. The waning Moon didn’t rise until 11:30 p.m., leaving me a couple of hours of dark sky to shoot these and other images.

To record the scene I shot and composited two versions of the image:

– one from a stack of four tracked images where the camera followed the stars on a small mount (the Sky-Watcher Star Adventurer) in order to build up the image and, admittedly, record far more detail and colour than your eye could ever see in the Milky Way.

– the sharp landscape comes from another stack of four images where I turned the tracking drive off so the ground wouldn’t blur. Stacking them helps reduce noise.

I composited the two sets of images, masking the sky from the untracked images and the ground from the tracked images. Perhaps that’s all a bit of trickery but the scene is real – the Milky Way really was there behind Athabasca Glacier.

Each sky exposure was 3 minutes, each ground exposure 4 minutes, all with the 24mm lens at f/2.5 and the Canon 6D at ISO 1250.

Rocky Mountain Nights – A Time-Lapse Collage


 

My new 4-minute video presents time-lapse and still images shot in the Rockies this past summer.

It’s been a busy summer for shooting. Since July I’ve spent a week each in Banff, Jasper and Waterton Lakes National Parks shooting nightscape stills and time-lapse videos of Alberta’s famous Rocky Mountain landscapes by night. 

This compilation includes some of the best footage, plus some panned still images, set to a wonderful piece of royalty-free (i.e. legal!) music by Adi Goldstein. 

For many of the sequences I employed “motion control” (MoCo) devices that incrementally move the cameras during the one to three hours that they are taking the 200 to 450 frames needed for a time-lapse sequence. 

I used the compact single-axis Radian, the 2-axis eMotimo, and the Dynamic Perception Stage Zero dolly, now equipped with their new Stage R single-axis panning unit. This was the first summer with the eMotimo and Stage R, so I’m still learning their best settings for speed, angles, and ramping rates. 

In recent blogs you’ve seen many still images shot as part of these sequences, or with other cameras dedicated to shooting stills. Now you get to see some of the time-lapse videos that represent many nights of shooting, and many hours sitting in the car waiting for the automated camera gear to finish its shooting task. 

Time-lapse shooting is an exercise in dedication and self-denial!

I hope you enjoy the result. Do click on the Enlarge button to go full-screen. Or visit my Vimeo site to watch the video, and others, there.

Stars on Ice – The Columbia Icefields by Moonlight


Star Trails over Columbia Icefields

The stars trail over the glaciers of the Columbia Icefields.

What an amazing night this was! You rarely get pristine cloudless skies over the Icefields. Some cloud is almost always blowing off the ice. But last Saturday in Jasper National Park was as clear as it gets.

The Moon was bright, as a waxing gibbous just off frame at left. It lit the landscape like it was day.

I shot with two cameras, one doing a time-lapse motion control sequence panning across the scene. The other was a fixed camera shooting 20-second exposures at 1-second intervals. The resulting frames from the fixed camera, 270 in this case, are multi-purpose:

– I stacked about 100 of them to make the star trail composite above. Two frames supplied the stars at the beginning and end of the trails. Another single frame supplied the ground, to avoid the shadows being blurred by the Moon’s motion if you used the ground composited from all 100 frames.

– I can also take the full set of 270 frames and sequence them into a time-lapse movie of the stars moving over the landscape.

Stars over the Columbia Icefields Panorama

Before beginning the time-lapse sequences I shot this 180° panorama, made of 5 segments stitched in PTGui software. It extends from the southwest at left, where the Milky Way is barely visible, to the north at right, with the Big Dipper over the Icefields Parkway.

Click on it for a bigger view.

Shooting at the Icefields

This is the camera setup, with the camera on the right taking the star trail image I feature at top.

The Athabasca Glacier is at left, the Stutfield Glacier at right.

Icefields Parking Lot at Night

Midnight under moonlight is when to see the Icefields! This is the lower parking lot, at the start of the trail up to Athabasca Glacier. This is packed with cars, RVs and buses by day, but at night I was the only one there.

Stars over Mt. Edith Cavell


Mt Edith Cavell by Starlight

The stars of the summer sky shine over the North Face of Mt. Edith Cavell.

The valley below Mt. Edith Cavell in Jasper National Park is one of the most impressive locations in the Canadian Rockies. At few other sites do you get the sense of standing at the foot of a vertical mountain face.

I shot this view last Friday night, when the waxing Moon was behind the mountain, lighting the clouds and sky but not the mountain and valley directly.

But enough scattered light came from the sky to light the foreground and mountain face to make a nice photo with detail in both earth and sky.

Use of highlight and shadow recovery in Adobe Camera Raw also helps a lot!

Mt. Edith Cavell Trail at Twilight Panorama

This view is a 360° ground-to-zenith panorama I shot earlier in the evening in twilight. It’s from the Trail of the Glacier path, where the path crosses Cavell Creek.

Mt. Edith Cavell was named in 1916 after the World War One nurse who was executed by the Germans for assisting allied soldiers escape occupied Belgium.

Pyramid Island Sky Panorama


Panorama from Pyramid Island Boardwalk, Jasper Park

The sky presents a panoramic show from Pyramid Island in Jasper National Park.

What a wonderful place to watch the stars. Last night I walked out to Pyramid Island in Jasper, via the historic boardwalk built in the 1930s. The site provides a panorama view around the lake and sky.

To the left is the “mainland.” Just left of centre the waxing gibbous Moon is setting over Pyramid Lake.

To the right of centre, the boardwalk leads out the small island, with Pyramid Mountain behind it.

To the right of the frame, a faint aurora glows to the northeast over the still waters of the lake.

This is a 360° panorama shot with the 15mm full-frame fish-eye lens in portrait orientation, with the segments stitched with PTGui software.

Big Dipper over Pyramid Mountain from Pyramid Island

After shooting some panoramas I walked to the end of the island and shot this view looking north and northwest to Pyramid Mountain. The Big Dipper is to the right of the peak, and the aurora lights up the northern horizon at right.

As I shot these images, the night was absolutely quiet. Until the wolves began to howl at the north end of the lake, in mournful howls that echoed across the waters.

It was one of the most spine-chilling moments I’ve experienced in many years of shooting landscapes at night.

Star Trails over Athabasca Falls


Star Trails over Athabasca Falls

The autumn stars rise in trails over Athabasca Falls and Mt. Kerkeslin in Jasper National Park.

Last night was a good one for shooting nightscapes in Jasper. Skies cleared for a beautiful moonlit night, ideal for nightscape shooting.

I went to Athabasca Falls, a popular scenic attraction in Jasper but deserted after dark. I set up cameras at the usual overlook, shooting both a time-lapse and star trail set.

The main image above is the result of stacking 100 images in the star trail set. I used the Advanced Stacker Plus actions from Star Circle Academy.

The foreground comes from one image, shot early in the sequence when the Moon lit more of the landscape. The Falls themselves remained in shadow, as I had expected from my lighting angle calculation and knowing the site.

The star trail image shows the autumn stars of Andromeda, Cassiopeia ad Perseus rising over Mt. Kerkeslin, the famous backdrop to Athabasca Falls on the Athabasca River, making its way to the Arctic Ocean

Mt Kerkeslin & Athabasca River at Twilight

This image is a 4-segment panorama I shot earlier in the evening in the twilight, with the waxing Moon over the Athabasca River.

In the early 1800s, after explorer, astronomer, and fur trader David Thompson had to abandon his original route over the Rockies at Howse Pass, he came north, and followed the Athabasca and Whirlpool Rivers up over the Athabasca Pass, his new main route to the B.C. interior.

Big Dipper over Pyramid Mountain


Big Dipper over Pyramid Mountain

The Big Dipper shines through clouds over Pyramid Mountain in Jasper National Park.

This week I am in Jasper National Park for a shoot of moonlit nightscapes, weather permitting.

It barely permitted last night, as clouds cleared briefly to the north. I visited a favourite spot on the shore of Patricia Lake, with Pyramid Mountain as a backdrop to the north.

The sky was still lit by the setting Moon, and by some faint aurora. The landscape is lit by starlight.

With luck I’ll get more images of Jasper by night this week, in one of Canada’s largest Dark Sky Preserves.

Circling Stars over Pyramid Mountain


The previous post showcased one image taken last Saturday night at Patricia Lake. This is a composite of 98 such frames, producing an image of stars circling the sky.

This is the motion of the northern sky over 75 minutes, as the Big Dipper and other circumpolar stars arc around the celestial pole, just off camera here. A few faint meteors streak at left. And the makings of an aurora appears at right.

Each exposure was 45 seconds long. I used a Photoshop Action to automatically select each frame in turn and stack it on top of the previous image, then change the blend mode to Lighten and flatten the layers. The end result of the computer crunching away is an image that recreates what we used to achieve with film, by stopping down the lens and exposing a slow ISO film for an hour or more onto one frame.

I last shot this same scene a decade ago with just that technique and Fuji Velvia film, a favourite of mine back then for star trails. But these days shooting multiple short exposures digitally provides the advantage of also netting a folder-full of images suitable for a time-lapse movie, something we could never do with film cameras, unless they were modified movie cameras. I like DSLRs better.

The Big Dipper Over Pyramid Mountain


 

Pyramid Mountain is Jasper’s iconic peak dominating the skyline of the mountain town in Alberta. The mountain and its foreground lakes are ideally placed for nightscapes of the northern sky.

I took this shot Saturday night, July 28, from the shore of Patricia Lake, one of several that dot the benchlands south of Pyramid Mountain. Small lakes like Patricia have the benefit of often being calm and reflective. Here the stars of the Big Dipper and Ursa Major swing over top of Pyramid Mountain, in the blue moonlit sky. A few well-placed clouds add a welcome perspective. This is one frame of 150 or so in a time-lapse sequence, and that will eventually become a star trail composite as well. But this single frame stands well all on its own.

The last time I was here shooting this same scene I was using Ektachrome and Fujichrome film (each had its unique characteristics, though just what I can’t recall!). That was more than a decade ago. This digital shot with the Canon 7D looks far better than what I got back then.

Lunar Reflections at Lac Beauvert


After a day of cloud and rain, skies cleared to provide a stunning twilight scene of the Moon reflected in the calm waters of Lac Beauvert in Jasper National Park.

This is the view from the dock at the prestigious and posh Jasper Park Lodge, where the rich and famous stay when in Jasper. I was there just to shoot the sky. In the distance is the distinctive snow-covered peak of Mount Edith Cavell, a Jasper landmark. Above it shines the waxing gibbous Moon in the twilight colours.

Athabasca Falls by Night


Athabasca Falls is one of the most popular and photographed attractions in Jasper National Park – by day. But by night, the falls on the Athabasca River are deserted.

In the distance, the stars rise behind Mount Kerkeslin. In the foreground, the river plunges into a deep gorge. These waters, with headwaters at the Columbia Glacier in the Icefields to the south, eventually make their way north to the Arctic Ocean.

I was at the Falls last Friday night, to shoot them by moonlight and under the stars. But in this case, I provided added foreground illumination from a flashlight.

As I took this and other shots, flashes of lightning from nearby thunderstorms occasionally lit the night. I had a couple of hours of clear skies before clouds moved in for the night, enough time to get frames for a time-lapse movie and some still frames like this one.

Athabasca Moon


I’ve spent the last couple of night in Jasper National Park, home to the world’s largest Dark Sky Preserve, dedicated to maintaining the darkness of the natural night sky.

This is a scene from Friday night, taken well before darkness, as the waxing Moon shone in the twilight above the Athabasca River and the peaks of the continental divide. For many years in the early 19th century fur traders plied these waters. Now rafters do.

Jasper is far enough north of me that I don’t get there very often. I’ve been spending most of my mountain time in Banff. I realize it’s been a decade or more since I’ve driven all the way up the Icefields Parkway to visit Jasper. But I was happy to be back. It has some great sites for nightscape photography.

I got two clear nights this past weekend, so a few more shots will hit the blog in the next few days.
