February 28, 2017 - The late winter evening zodiacal light from Dinosaur Provincial Park, Alberta, Canada. The light is the glow from sunlight reflecting off cometary dust particles in the inner solar system. It is not an effect of twilight. It is best visible in the evening from northern latitudes in late winter and spring. Venus is just setting above the badlands landscape. The Andromeda Galaxy is at right, the Pleiades at left. The Milky Way runs across the frame at top.

February 2, 2017 - Orion and the Dog Stars (Procyon and Sirius) rising over a frozen Lake MacGregor in southern Alberta on a clear moonlit night, with a 6-day moon lighting the scene. Note the glitter path reflection of Sirius in the ice. The last of the evening twilight lights the horizon at right.

February 2, 2017 - Orion and the Dog Stars (Procyon and Sirius) rising over a frozen Lake MacGregor in southern Alberta, Canada, on a clear moonlit night, with a 6-day moon, off frame, lighting the scene. Note the glitter path reflection of Sirius in the ice.

November 27, 2017 - The winter stars and constellations rising over the moonlit badlands of Dinosaur Provincial Park, Alberta, Canada. Orion is at centre; Taurus above, and Gemini at left. Sirius is just rising above the hill in the distance at centre.

February 28, 2017 - A 360 degree panorama of the winter sky over Dinosaur Provincial Park, Alberta, Canada. The Milky Way arches across the sky from south (left) to northeast (right). The zodiacal light stretches up from the western horizon at centre. The Gegenschein is faintly visible above the horizon at far left in Leo. Orion is left of centre; the Pleiades sit at the tip of the zodiacal light pyramid of light. The ground is lit only by starlight. No artificial illumination or light painting applied.

March 19, 2017 - A horizon-to-zenith panorama of the winter consellations as they set into the southwest, Alberta, Canada. Orion is at bottom centre, with his Belt pointing down to Canis Major and up to Taurus. Gemini and Auriga are at top, in this case near the zenith overhead. The bright star clusters, M44, the Beehive, (at left) and M45, the Pleiades, (at right) flank the Milky Way. M45 is embedded in the zodiacal light. The star clusters M35 in Gemini and M41 in Canis Major are also visible as diffuse spots, as are several other star clusters. A couple of satellite trails are visible.

A 360 degree fish-eye scene of the winter sky taken in southern Alberta, Canada, with Orion rising into the southeast at bottom, and Venus bright as an evening star in the west at right. The Big Dipper is low in the northeast at upper left. The Milky Way runs across the sky from northwest where summer stars are setting to the southeast where the winter stars are rising. Sirius is just rising behind the distant trees at lower left. Overhead are the autumn constellations of Cassiopeia. Andromeda, and Perseus. Below centre is the Pleiades and stars of Taurus. Some faint zodiacal light is visible at right in the southwest, near Venus but competes with the haze and lights from towns to the west.

February 28, 2017 - A 360 degree panorama of he winter sky and Milky Way at Dinosaur Provincial Park in southern Alberta, Canada, on a very clear night. The Milky Way stretches across the sky from south (bottom) to northwest (at top right). The zodiacal light stretches up from the horizon in the west at right, and can be traced faintly across the sky to the east (at left) where there is a dim glow of Gegenschein visible. The view is looking south and in this scene the galactic anti-centre is near the centre of the image. We are looking toward the outer edge of the Galaxy, to the outer spiral arms opposite the galactic centre in Sagittarus, visible in summer. Orion is at bottom centre, almost due south. North is at top.

February 28, 2017 - A 200+ degree panorama of the arch of the winter Milky Way, from south (left) to northwest (ar right) with the zodiacal light to the west at centre. This was from Dinosaur Provincial Park in southern Alberta, Canada.

January 12, 2017 - A 300 degree panorama of the winter evening sky with the Full Wolf Moon of mid-winter rising at left in the northeast, and Venus (brightest) and Mars (above) over in the southwest at right. Orion is rising in the east at centre, with Taurus above. The Big Dipper is at far left to the north. The remaining glow of twilight creates an arch of light in the southwest, while the rising moon creates an arch of brighter sky at left. This was a very clear, transparent night but at -20 degrees Celsius. Note the glitter path on the snow from the moon. Photographed in southern Alberta, Canada.

February 28, 2017 - A 360 degree panorama of the evening twilight sky at Dinosaur Provincial Park, Alberta, Canada. The Milky Way is beginning to appear and the zodiacal light is at centre in the west. Clouds lit by light pollution colour the sky. The crescent moon, here overexposed, shines below bright Venus, with Mars much fainter to the left of Venus. Orion stands to the south at left of centre, partly in clouds. Numerous satellite trails appear in the blue twilight sky. Leo is rising at far left; the Big Dipper is at far right.

May 30, 2017 - A 200 degree panorama of the waxing crescent moon in the spring evening twilight over Lake MacGregor in southern Alberta, Canada. The Sun has set to the northwest at right and the moon shines in the west. To the southwest, at left. is Jupiter and Spica.

A panorama of the sunset colors, with the waxing crescent moon over Red Rock Coulee Natural Area near Seven Persons, Alberta, Canada. This is a classic prairie big sky country sunset. The moon is just right of centre. The rising Earth's shadow is darkening the sky above the horizon at far left.

June 2, 2017 - A 200 degree panorama of the waxing gibbous (8-day-old) moon in the spring evening twilight over Lake MacGregor in southern Alberta, Canada. The Sun has set to the northwest at right and the Moon shines in the west. To the left of the moon is Jupiter and Spica.

July 16, 2017 - A 120 degree panorama of the dawn sky with the northeast horizon (left) colorful with dawn twilight, Venus in the east (centre) near Aldebaran, and the waning last quarter moon in the southeast (at right). This serves to demonstrate the 90 degree angle between the waning quarter moon and the sunrise point (and the Sun). And also the twiight colors on a very clear morning. The sky is also much darker toward the moon at the 90 degree point due to natural sky polarization.

The waxing 4-day-old crescent moon in the twilight sky at Red Rock Coulee, Alberta, Canada. A lovely contrast of sky and earth tones.
