Late Winter/Early Spring Sky Panorama with Aurora

A 360° panorama of the late winter and early spring sky with an arc of aurora, from a latitude of 51° N. This was March 13, 2021, from home in southern Alberta. This night there was a bright aurora across the northern sky, so I have oriented the view to place due north just right of centre. The Big Dipper is at right; Leo is rising at far right. The bright winter stars around Orion are at far left to the south. High clouds and haze, partly lit by light pollution here, add the natural glows to the stars, emphasizing the bright stars and constellation patterns. No filter was used here. The yellow arch at left is a band of cloud illuminated by light pollution. This was a test of new panorama gear, using an Acratech Pan Head on top of a Alyn Wallace/MSM Z-Plate mounted to a Sky-Watcher Star Adventurer 2i tracker, to allow taking tracked segments for the panorama, to prevent star trailing. The Z-Plate allowed the Pan Head to mount and move horizontally and vertically in azimuth and altitude despite being on a polar aligned tracker. It worked! The ground is a stitch of 8 segments shot with the tracker motor off, then blended with a stitch of 20 segments for the sky, in 3 tiers of 8 + 6 + 6 segments, all with the Sigma 24mm lens at f/2.8 and for 1-minute with the Nikon D750 at ISO 1600 for all shots. Stitched with PTGui v12 which at last saves camera metadata when exporting PSD files. The original is 25,600 pixels wide.

Winter Sky Panorama — 360° Rectangular

A 360° panorama of the entire late winter/early spring sky from northern latitudes, with the winter Milky Way stretching across the sky, from south (at left) to north (at right). West is at centre. Orion and the northern winters stars are left of centre to the southwest. Just below the prominent Pleiades cluster at centre is Mars, then near the Pleiades in early March 2021. To the far left in the eastern sky the spring stars are rising. The Beehive star cluster stands out to the left of the Milky Way,. The Big Dipper is at upper right. Arcturus is rising at far right just above the horizon. Sirius is above the southern horizon left of centre. The faint glow of Gegenschein is at far left below Leo, opposite the Sun. I shot this from home on March 7, 2021 on a very clear night with no aurora to the north. This is from a latitude of 51° N. This is a stitch of 21 segments, in 3 tiers or rows of 7 segments each, with the Sigma 24mm Art lens at f/2 and Canon EOS Ra camera at ISO 1600. Exposures were 30 seconds each, all untracked. The camera was moved automatically from frame to frame by placing it on the Sky-Watcher AZ-GTi motorized alt-azimuth mount, programmed with the hand controller from the old Sky-Watcher All-View mount. Stitching was with PTGui using equirectangular projection. The original is 28,000 by 8,000 pixels.

Winter Sky Panorama — 360° Spherical

A 360° panorama of the entire later winter/early spring sky from northern latitudes, with the winter Milky Way stretching across the sky, from south (at bottom) to north (at top). Orion and the northern winters stars are at bottom to the southwest. Just below the prominent Pleiades cluster at right is Mars. To the left in the eastern sky the spring stars are rising. I shot this from home on March 7, 2021 on a very clear night with no aurora to the north. South is at bottom; north is at top. East is to the left; west is to the right, toward the major source of light pollution. Polaris is at top centre; the Big Dipper is at upper left. Arcturus is rising at left. Sirius is at bottom, above the southern horizon. This is from a latitude of 51° N. This is a stitch of 21 segments, in 3 tiers or rows of 7 segments each, with the Sigma 24mm Art lens at f/2 and Canon EOS Ra camera at ISO 1600. Exposures were 30 seconds each, all untracked. The camera was moved automatically from frame to frame by placing it on the Sky-Watcher AZ-GTi motorized alt-azimuth mount, programmed with the hand controller from the old Sky-Watcher All-View mount. Stitching was with PTGui. The original is 17,000 by 17,000 pixels.

Jupiter, Saturn and the Milky Way

Jupiter and Saturn nearing their December 21, 2020 Great Conjunction, with this image taken December 3, 2020 from the Allen Bill flats area on the Elbow River in the Kananaskis Country southwest of Calgary, Alberta. This is a blend of 4 untracked images for the dark ground, stacked to smooth noise, for 2 minutes each at ISO 400, and two tracked images for the sky for 30 seconds at ISO 1600, all with the 35mm Canon lens at f/2.8 and Canon EOS Ra. A dodge and burn layer created by Lumenzia applied. The tracker was the Sky-Watcher Star Adventurer 2i. Taken before moonrise.

Zodiacal Light with Venus and Mars

The Zodiacal Light before dawn on September 21, 2020 with Venus bright in the Zodiacal Light at left of centre, and Mars bright at far right. Orion and the winter stars are at centre. The Big Dipper is at far left/ This is a panorama of 6 segments, each untracked for 25 seconds at f/2 with the 14mm Sigma Art lens on the Nikon D750 at ISO 1600, and stitched with Adobe Camera Raw.

Milky Way over Mount Andromeda at Moonset

The Milky Way and galactic core area over Mount Andromeda (centre), Mount Athabasca (left) and the Athabasca Glacier (right) at the Columbia Icefields, on a very clear night July 27, 2020. I shot this as the waxing quarter Moon was still up but behind Snow Dome at far right, and about to set. Warm low-angle moonlight illuminates the peaks at left with “bronze hour” lunar alpen glow, and brightens the sky at right, plus adds the blue tint to the sky. But in the clear mountain air, the Milky Way and its starclouds still show up very well. The constellations of Aquila and Scutum are at centre. This is an exposure blend of 4 x 1.5-minutes, untracked at f/2 at ISO 1600 for the ground, followed immediately by 3 x 1.5-minutes at f/2.8 and ISO 3200 for the sky, with the sky exposures tracked on the iOptron SkyGuider Pro tracker. All with the 20mm Sigma Art lens and Canon EOS Ra, with the lens adapted to the camera with a Metabones adapter.

Comet over the Columbia Icefields at Moonset

Comet NEOWISE (C/2020 F3) on July 27, 2020, at right, over the Columbia Icefields with the Moon still lighting the peaks in a warm “bronze hour” light for a lunar alpenglow. The Moon is behind Snowdome Peak at centre and is also still lighting the sky a deep blue. The Milky Way is at left over Mount Andromeda. Arcturus is the bright star at top centre. This was more or less my parting shot of the comet, as it was fading rapidly at this time receding from Earth, though it was still naked eye. Plus the waxing Moon was going to be lighting the sky much more in the following week. So this was the night! Shooting a week earlier when the comet was brighter and larger would have been nice, but clouds would have got in the way. This was shot during a run of unusually clear nights at the Icefields, the first good clear nights according to the locals. I shot this during the brief “bronze hour” interval immediately after the Moon had disappeared behind Snowdome but was still lighting the peaks. So to be clear — the peaks are lit by the setting Moon, not by the Sun. This is not a composite of day and night shots; it is a well-timed and planned panorama shot as quickly as possible over a few minutes before the lighting changed. Lingering twilight lights the horizon down the Sunwapta Valley at right. The famous Athabasca Glacier is just left of centre; Snowdome Glacier is right of centre, with the glacial Sunwapta Lake in the foreground. Mount Athabasca is at far left with its glacier. This is a 17-segment (!) panorama with the 35mm Canon lens at f/2.5 and Canon EOS Ra camera at ISO 1600, for 20 seconds each, untracked. The overlap was more than is normally needed but the segments stitched perfectly with Adobe Camera Raw, which is not always the case with such scenes. LENR employed on all segments when shooting on this warm night. Dodging and burning applied to accentuate highlights and shadows. Topaz Sharpen AI applied. The original is over 27,000 pixels wide.

Milky Way Through the Pines

The summer Milky Way with the Summer Triangle stars through pine trees, shot from the Howse Pass Viewpoint at Saskatchewan River Crossing, Banff National Park, Alberta. Jupiter is the bright object at the bottom. This is an exposure blend of a stack of 4 x 2-minute untracked exposures at ISO 6400 for the ground and 2 x 1-minute tracked exposures at ISO 6400 for the sky, with the Canon 15mm full-frame fish-eye lens at f/2.8 and Canon EOS Ra camera. The camera was on the iOptron SkyGuider Pro tracker. An Orton soft glow filter added with Luminar Flex. Lights from the Saskatchewan Crosssing Resort lights the treetops.

Planets and Milky Way Over Saskatchewan River Crossing

Jupiter (brightest), Saturn (to the left), and the Milky Way over the Saskatchewan River and the area of Howse Pass, on July 26, 2020. Mount Cephren is at left; the scene is framed to include Cephren. The nebulas and star clouds of the galactic centre area at right show up well on this very clear night. The bright Small Sagittarius Starcloud, aka M24, is most obvious, flanked by the star clusters M23 and M25 to the side, and the nebulas M17 and M16 above, and M8 and M20 below. The fuzzy globular cluster M22 is to the left of the large Lagoon Nebula, M8. Green airglow tints the sky. This is an exposure blend of a stack of 4 x 2-minute untracked exposures for the ground at ISO 1600 (exposed long to bring out ground details), with 2 x 1-minute tracked and stacked exposures at ISO 3200 for the sky. Shot from the Howse Pass Viewpoint area off the Icefields Parkway at Saskatchewan River Crossing. The camera was on the iOptron SkyGuider Pro tracker. For the ground shots I simply turned the tracker motor off. All with the 35mm Canon lens at f/2.8 and Canon EOS Ra, a filter-modified camera. Topaz Sharpen AI applied to the ground; Topaz DeNoise AI applied to the sky. In camera LENR employed on all shots on this warm night. An Orton soft glow effect added to the sky with Luminar Flex plug-in.

Milky Way and Planets over Waterton Lakes (July 2020)

The galactic core area of the Milky Way over Waterton Lakes National Park, Alberta with the pairing of giant planets from summer 2020. Jupiter is the bright object at centre, with Saturn dimmer to the left (east) of Jupiter. In 2020 the two planets were close together in the summer sky. Sagittarius is at right. The Prince of Wales Hotel is the bright light source. This was July 13-14, 2020. This is a stack of 10 exposures for the ground, mean combined to smooth noise in the dark foreground, with the sky from one exposure, all untracked for 25 seconds at f/2 with the Sigma 20mm lens on the Canon EOS Ra camera at ISO 3200. A single short exposure is blended in for just the hotel lights to prevent them from being too overexposed. Stacked, masked and blended in Photoshop.

Milky Way over Maskinonge Pond

The galactic core area of the Milky Way over Maskinonge Pond in Waterton Lakes National Park, Alberta. Jupiter is the bright object at left, with Saturn dimmer to the left (east) of Jupiter. In the summer of 2020 the two planets were close together in the summer sky. Jupiter provides the glitter path on the water. Antares and Scorpius are to the right. Sagittarius is at centre. This was July 13-14, 2020. As is typical of Waterton, it was windy enough tonight that there was no sharp reflection of the stars and Milky Way in the water. This is a stack of 12 exposures for the ground, mean combined to smooth noise in the dark foreground, with the sky from one exposure, all untracked for 30 seconds at f/2 with the Sigma 20mm lens on the Canon EOS Ra camera at ISO 3200. Stacked and blended in Photoshop.

Backyard Milky Way with Jupiter and Saturn Rising

The late-night spring Milky Way from my rural backyard in Alberta (latitude 51° N) on a fine May night in 2020, with the waxing Moon just setting and lighting the landscape and sky. Jupiter (brightest) and Saturn to the east (left) are just rising together at left, east of the Milky Way. West of the galactic centre at right is red Antares in Scorpius. The Small Sagittarius and Scutum starclouds are prominent at centre, with their various Messier nebulas and star clusters visible. This is a stack of 4 x 2-minute tracked exposures for the untrailed sky blended with a stack of 4 x 2-minute untracked exposures for the sharp ground, with the 20mm Nikon F-mount Sigma Art lens on the Canon EOS Ra camera using the Metabones Nikon F to EOS R lens adapter. I shot this as a test of the lens adapter. Taken May 27/28, 2020. The camera was on the iOptron SkyGuider Pro tracker.

Selfie at Grasslands National Park

A selfie of me shooting time-lapses and tracked Milky Way images at the 76 Ranch Corral site at Grasslands National Park, August 27, 2019. Taken for use as a book cover. High cloud and a dark aircraft contrail drifting through added the star glows and the dark streak. Jupiter, at right, and Saturn, at left, flank the Milky Way. Altair is the bright star at top. This is a stack of 10 x 30-second exposures for the ground to smooth noise and one exposure for the sky and for me, to minimize trailing and movement. All with the Sony a7III at ISO 6400 and Venus Optics 15mm lens at f/2. LENR on. Orton Glow effect added with Luminar Flex.

The Galactic Centre at Grasslands (with Labels)

The core of the Milky Way in Sagittarius low in the south over the Frenchman River valley at Grasslands National Park, Saskatchewan. This is from the 76 Ranch Corral site. Grasslands is a Dark Sky Preserve. The frame takes in the openj star clusters M6 and M7 just above the horizon in Scorpius, on up through the Sagittarius Starcloud and galactic core, then up past the red nebulas M8 and M20, the Small Sagittarius Starcloud M24 flanked by the clusters M23 and M25, then the nebulas M17 and M16 at top in Serpens. The globular cluster M55 is visible at far left. Jupiter is bright at right above reddish Antares, Saturn is dimmer at left, to the left of the globular cluster M22. I shot this August 27, 2019. This is a stack of 5 x 3-minute tracked exposures for the sky (to avoid star trails) blended with a stack of 5 x 3-minute untracked exposures for the ground, all with the 35mm Canon lens at f/2.8 and filter-modified Canon 5D MkII camera at ISO 1600. The tracker was the Star Adventurer.

Milky Way at the Old Barn

The galactic centre area of the Milky Way in Sagittarius behind the grand old barn near home in southern Alberta, on June 30, 2019. Illumination of the barn is from twilight to the north, but also from light pollution skyglow from the west off frame at right. The sky is blue from the perpetual summer twilight at this time of year. Jupiter is at centre. The nebulas and starclouds of the Milky Way show up well here. The southerly Messier clusters, M6 and M7, in Scorpius just skim the horizon at left. The very red star in the “eye” of the Dark Horse is TW Ophiuchi. This is from my latitude of 51° N. This is a blend of tracked (for the sky) and untracked (for the ground) exposures, with a stack of 3 for the ground and 5 for the sky, stacked to smooth noise. All at ISO 1250 and one minute each, but with the sky exposures at f/2 and ground exposures at f/2.5, with the Sigma 24mm Art lens and stock (not modified) Nikon D750. The sky exposures were through a NiSI Natural Night light pollution filter. The sky exposures are at f/2 to make up for the light loss from shooting thru the filter while keeping exposures short for ease of blending later. The tracker was the Sky-Watcher Star Adventurer. I added a mild Orton effect glow layer to the image using Luminar Flex.

Winter Sky Setting at Dinosaur Park Panorama

A wide panorama of Orion and the winter stars setting on a spring evening at Dinosaur Provincial Park, with the Zodiacal Light rising out of the twilight and distant yellow sky glow to the west at centre. Sirius is at left to the southwest, with Orion setting behind the badlands hill, while the Pleiades is in the Zodiacal Light band at centre, with Mars just below the Pleiades. Perseus, Cassiopeia, and the Andromeda Galaxy are setting at right in the northwest. High haze and aircraft contrails (one at centre) add the natural star glows. The lingering twilight adds the sky colour. This is a 240° panorama stitched from 17 segments, all with the 24mm Sigma Art lens and Nikon D750 in portrait orientation, each segment 20 seconds at f/1.4 and ISO 3200. Stitched with Adobe Camera Raw. A mild Orton glow effect was added to the landscape with Luminar 3 plugin.

Perseid Meteor and Observers at Star Party

A Perseid meteor streaks down the Milky Way over the Saskatchewan Summer Star Party in the Cypress Hills of southwest Saskatchewan, at Cypress Hills Interprovincial Park, a Dark Sky Preserve. The Milky Way shines to the south. About 350 stargazers attend the SSSP every year. Observers enjoy their views of the sky at left while an astrophotographer attends to his camera control computer at right. This is a single exposure, 25 seconds, with the Laowa 15mm lens at f/2 and Sony a7III camera at ISO 3200.

Stargazer Under the Milky Way at Star Party

An observer gazes skyward with his Dobsonian reflector telescope at the Saskatchewan Summer Star Party on August 9, 2018, in the Cypress Hills of southwest Saskatchewan, at the Cypress Hills Interprovincial Park, a Dark Sky Preserve. The Milky Way shines to the south. Smoke in the sky obscures the horizon somewhat. About 350 stargazers attend the SSSP every year. This is a single 25-second exposure with the Loawa 15mm lens at f/2 and Sony a7III at ISO 3200.

Gazing at the Milky Way in Grasslands National Park (Portait)

A Park interpreter poses for a scene in Grasslands National Park, Saskatchewan, of stargazing with binoculars under the Milky Way on a dark moonless night. Grasslands is perfect for stargazing as it is a Dark Sky Preserve and the horizon is vast and unobstructed. Mars is bright to the left and the galactic centre is to the south at right. The view is overlooking the Frenchman River Valley. This is a stack of 4 exposures for the ground and one untracked exposure for the sky, all 30 seconds at f/2.8 with the 20mm Sigma lens and Nikon D750 at ISO 6400. LENR was on.

Mars and Milky Way over Tipis at Grasslands

Mars and the Milky Way over the tipis at Two Trees area in Grasslands National Park, Saskatchewan on August 6, 2018. Some light cloud added the haze and glows to the planets and stars. Illumination is by starlight. No light painting was employed here. This is a stack of 8 exposures for the ground, mean combined to smooth noise, and a single untracked exposure for the sky, all 30 seconds at f/2.8 with the Sigma 20mm lens, and Nikon D750 at ISO 6400 with LENR on.

Mars and Milky Way over Tipi at Grasslands

Mars (at left) and the Milky Way (at right) over a single tipi (with another under construction at back) at the Two Trees site at Grasslands National Park, Saskatchewan, August 6, 2018. I placed a low-level warm LED light inside the tipi for the illumination. This is a stack of 6 exposures, mean combined to smooth noise, for the ground, and one untracked exposure for the sky, all 30 seconds at f/2.2 with the 20mm Sigma lens and Nikon D750 at ISO 3200.

Stellar Reflections at Herbert Lake

The view looking south at Herbert Lake, Banff National Park, Alberta, with the Milky Way over Mount Temple and the peaks of the Continental Divide. Mars (left in clouds) and Jupiter (right) flank the Milky Way, while Saturn sits within the Milky Way. A couple of satellites and possibly a meteor (it could be a flaring satellite) punctuate the sky as well. The sky is blue with the last vestiges of twilight and from moonlight from the setting waxing Moon off frame at right. This is a four exposures for the ground mean combined to smooth noise, and one exposure for the sky and reflections, all 30 seconds with the Laowa 15mm lens at f/2 and Sony a7III at ISO 3200.
