<![CDATA[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.
