$The conjunction of the waxing 4-day-old crescent Moon below the Pleiades,and set in a slightly hazy sky on March 25,2023. The haze adds the colourful "lunar corona" halo around the bright crescent of the Moon from diffraction effects in the high icy clouds. Shot before the sky got dark,the remaining twilight adds the blue to the background sky. Earthshine is visible on the dark side of the Moon.$

The galactic centre area in Sagittarius (at left) and Scorpius (at right) low in the south on a summer night at Dinosaur Provincial Park, Alberta. This was June 30/July 1, 2022. Being just 10 days after summer solstice and at latitude +50° North, the sky even to the south still has a blue tint from all-night twilight. I made no attempt to neutralize the sky colouration. In addition, some haze from smoke discoloured the sky and reduced transparency and contrast low in the sky.

A panorama of Lake Edith in Jasper National Park, Alberta, on a calm autumn night, looking north to the stars of Ursa Major, the Great Bear, and the Big Dipper in deep twilight. Arcturus is at far left setting in the northwest over Pyramid Mountain, while Capella in Auriga and the stars of Perseus are rising at right in the northeast. This was on a mid-October night when the Big Dipper rides low in the northern sky from this latitude of 53° N.

The colourful region around yellow Antares (bottom) in Scorpius and blue Rho Ophiuchi (top) in Ophiuchus. The nebulas are largely reflection nebulas, taking on the colour of the stars embedded in the nebulas. However, the field also contains a lot of emission nebulosity, hydrogen gas glowing red and magenta. Plus there are fingers of brown dark dusty nebulosity. It is one of the most colourful regions of the sky.

Comet NEOWISE (C/2020 F3) reflected in the still waters this night of Crawling Lake in southern Alberta. A dim aurora at right colours the sky magenta. Lingering twilight colours the sky blue. A meteor or more likely a flaring satellite appears at right and is also reflected in the water. Even in this short exposure, the two tails — dust and ion — are visible. This was July 20, 2020.

The Full Moon at the equinox, on March 20, 2019, reaching full phase only fours hours after the moment of the vernal equinox, and here captured rising very shortly before the moment of the Full Moon. I shot this while the Moon was still rising and in a deep blue sky, and tinted yellow from atmospheric absorption. Even so, this is a blend of short (for the Moon) and long (for the sky) exposures to capture the dynamic range.

The rising "supermoon" of July 12, 2022 embedded in the blue arc of Earth's shadow, rimmed by the pink Belt of Venus band of twilight colours, all over the badlands formations of Dinosaur Provincial Park on the Red Deer River in Alberta, Canada. The blue arc is the shadow of the Earth cast onto the atmosphere opposite the sunset point. The pink Belt of Venus is from red sunlight still illuminating the upper atmosphere, an effect that lasts only a few minutes at sunset or sunrise, and requires a very clear sky to show up, as it was this night.

The aurora of March 23,2023,caught early in the evening when there was a green arc to the south as the sky darkened that exhibited a "dunes" type of structure,with horizontal banding rather than vertical rays or curtains. Above is a purple arct that has some characteristics of a STEVE arc but is likely a standard vertical curtain. At right are Venus and the crescent Moon below,above the glow of twilight. Orion is left of centre,with Sirius embedded in the dunes arc. This is looking southwest to west. The time was about 9 pm MDT.

This captures the vertical sweep of the summer Milky Way over the foreground landscape of Dinosaur Provincial Park, Alberta. The image serves as a good illustration of the richness of objects, dark dust lanes and bright starfields along the Milky Way, from Sagittarius low in the south at bottom, to Cygnus at top. In between are Aquila and Scutum, with part of Ophiuchus at right. This was from latitude 50.5° North, where Sagittarius and the galactic centre are low in sky. The Summer Triangle stars of Deneb, Vega and Altair are at top.

The northern summer Milky Way setting over the mountains of Waterton Lakes National Park, Alberta, Canada, with warm golden lighting supplied by the rising waning Moon (behind the camera) illuminating the landscape and sky in a “moonstrike” effect. Taken on September 21, 2019, in frames taken as part of a time-lapse. Faint bands of red airglow tint the sky, though the blue sky colour is from the moonlight. This is taken during the lunar “golden hour.”

The unusual STEVE auroral arc over my house in southern Alberta, on May 6, 2018, on a partly cloudy night. A dim and inactive main aurora was to the north, but the Steve arc crossed the sky from east to west.

$One of a short series of images showing the development of an aurora display from a classic arc into a more complex pattern of concentric arcs and with loops and swirls. This was Feb 5, 2019 from the Churchill Northern Studies Centre. The outburst lasted only 5 minutes or so and might have been due to the Bz interplanetary field turning south briefly. After this series, the display faded and fractured into faint arcs and a diffuse glow across the sky.$

A vertical panorama of the summer Milky Way over the observing field at the Saskatchewan Summer Star Party, held in Cypress Hills Interprovincial Park in southwest Saskatchewan, Canada, at a latitude 49° N. The Park is a Dark Sky Preserve. This was August 26, 2022 on a perfect night of stargazing under very clear skies. The Milky Way extends from Sagittarius near the horizon, to Cygnus nearly overhead at this time, so a vertical sweep of 90°. I've left the satellite trails in for this scene.

A fish-eye lens / all-sky view of the STEVE aurora arc across the sky and in clouds on May 6, 2018, from home in southern Alberta, with a diffuse aurora to the north casting streaks of purple up the sky, and a green glow along the horizon. This night the aurora was very active to the north and east with a terrific display in Churchill, Manitoba about an hour before this, matching the usual STEVE characteristic of him appearing as a major storm subsides.

The rising Full Moon of January 6,2023 over the Badlands of Horseshoe Canyon,near Drumheller,Alberta. Here the Moon is set a dark blue crepuscular ray (or more correctly,anti-crepuscular ray) converging on the point directly opposite the Sun. The ray was a shadow cast by clouds in the west,which parted enough for a few moments for the setting Sun to light the foreground,making for a colourful contrast between ground and sky.

I shot this on the peak night of the shower, August 11/12 after moonset so the sky was dark and in fact filled with bright airglow, appearing here as bands of green and yellow, mixed with a low-level aurora to the north as well. While it looks like the sky has artificial light pollution, the glows here are natural, from aurora and airglow.
