Thin Moon and Jupiter Setting (March 22, 2023)
The thin one-day-old crescent Moon just above Jupiter as both set on the evening of March 22, 2023. The Earthshine glow is obvious on the dark side of the Moon. The age of the Moon was about 31.5 hours this night at this time and longitude. This is a single 1.6-second untracked shot with the Canon RF100-400mm lens at 270mm and f/8 (wide open at this focal length), on the Canon Ra at ISO 3200 to keep the exposure time short and with the Ra's red sensitivity enhancing the twilight colours. Topaz DeNoise AI applied to smooth the high ISO noise. A mild Orton glow added with Luminar Neo.
The Winter Milky Way over Badlands (with Labels)
A labelled panorama of the Milky Way on a February winter night over the Badlands of Dinosaur Provincial Park, Alberta. The panorama extends from Canis Major low on the horizon to Perseus at top near the zenith. Orion is at right of centre, with Gemini to the left and Taurus and Auriga above Orion. Mars is the bright reddish object in Taurus aboce similarly coloured but dimmer Aldebaran, itself amid the Hyades star cluster. The blue Pleiades is at upper right. Sirius is the bright star at bottom. The image takes in the complete Winter Hexagon (aka the Winter Circle) of bright stars. The Milky Way is peppered with red nebulas, notably the large curving arc of Barnard's Loop, a suspected supernova remnant in Orion. The lowest stretches of the Loop get lost in the bright red airglow. The bright Orion Nebula shines in Orion's Sword, while east (left) of Orion is the round Rosette Nebula in Monoceros. At top is the finger-like California Nebula in Perseus. Several Messier star clusters also show up along the Milky Way. The cyan-tinted Comet C/2022 E3 (ZTF) is above centre amid the Taurus Dark Clouds. Bands of red and yellow-green airglow tint the sky toward the horizon, as well as the glows from distant towns, notably Medicine Hat at centre. Some light haze added natural star glows — I did not use a starglow diffusion filter this night. But I did shoot the sky segments though an URTH broadband light pollution reduction filter, to help make the nebulas pop out more. This is a stitch of 6 segments (using Adobe Camera Raw) for the sky with segments taken at 15° intervals, each 1 minute with the tracker motor on and at ISO 1600. The resulting sky panorama is blended with a stack of 4 untracked images for the ground, each 2 minutes at ISO 800, taken about 40 minutes after the sky segments, when the waning gibbous Moon was rising to light the landscape with a warm side lighting. So this is a time blend. But the camera was not moved between image sets. All were with the Canon RF28-70mm lens at f/2.8 and 28mm, on the filter-modified Canon R camera from AstroGear. This was on the Star Adventurer tracker with an Alyn Wallace V-plate to keep the camera level and aid framing the panorama. Orton glow effects added to the ground with Luminar Neo, and to the sky with Radiant Photo and f/64 Diffusion actions. Star spikes added with AstronomyTools actions. A clean unlabelled version is available.

Orion and Sirius over the moonlit badlands of Dinosaur Provincial Park, Alberta on Feb. 4, 2023 with the waxing gibbous Moon providing the illumination on this very clear and mild night. This is a blend of two 30-second exposures: one untracked for the ground and one tracked for the sky, both with the RF28-70mm lens at f/4 and Canon R5 at ISO 200, on the Star Adventurer tracker. A mild Orton glow added with Luminar Neo and star diffraction spikes added with AstronomyTools actions. It was a perfect winter night, with the temperature only at 0° C and no wind.
The Winter Sky over the Badlands (with Labels)
The sparkling winter stars and constellations over the moonlit badlands of Dinosaur Provincial Park, Alberta on Feb. 4, 2023. The waxing gibbous Moon is off frame at left providing the illumination on this very clear and mild night. Captured here in a vertical panorama from below the horizon to past the zenith. Orion is below centre, with his Belt pointing down to Sirius and up to Aldebaran. Above reddish Aldebaran is Mars, as it was on Feb 4, 2023. Above Mars is the blue Pleiades cluster. At top left is the bright star Capella in Auriga. Just above Capella is the tiny cyan-coloured fuzzy spot that is Comet C/2022 E3 (ZTF), again where it was this night as it was heading southward into Auriga and Taurus, after its closest approach to Earth 3 days earlier. It was nearly overhead this night and an easy sighting in binoculars. I could not frame Castor and Pollux in Gemini as the Moon was too close to that area. A better night for Moon position and lighting geometry would have been a week later with the rising waning Moon, but the clouds did not allow that. I took this night and made the best of it! This is a blend of seven 30-second exposures: one untracked for the ground and a stitch of 6 tracked for the sky, all with the RF28-70mm lens at f/4 and Canon R5 at ISO 200, on the Star Adventurer tracker. The camera was oriented in landscape format and moved upward in increments of 15° per segment. The panorama segments had to be stitched with PTGui, but even then with difficulty as it required adding a lot of manual alignment points for it to successfully stitch all segments. I used the Transverse Cylindrical projection to retain the straight horizon and rectangular image format. A mild Orton glow added with Luminar Neo and star diffraction spikes added with AstronomyTools actions for a "sparkling" effect. It was a perfect winter night, with the temperature only at 0° C and no wind. It was just me there that night, me and the howling coyotes echoing across the valley. This version has labels. A clean version is also available.
The Winter Sky over the Badlands
The sparkling winter stars and constellations over the moonlit badlands of Dinosaur Provincial Park, Alberta on Feb. 4, 2023. The waxing gibbous Moon is off frame at left providing the illumination on this very clear and mild night. Captured here in a vertical panorama from below the horizon to past the zenith.

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. This is a single exposure with the Canon R5 and Canon RF100-400mm lens at 236mm. Most processing in Adobe Camera Raw with ground and sky masks. A mild glow layer added to the ground in Photoshop with Luminar Neo.
The Rising of the Winter "Wolf " Moon
The rising Full "Wolf" Moon of January 6, 2023 over the Badlands of Horseshoe Canyon, near Drumheller, Alberta. The sequence demonstrates the changes in colour of the rising Moon from atmospheric absorption, and changes in its shape from atmospheric refraction. This night the Moon was full almost at the same time as it rose from my location. However, the Moon's high northerly declination — it was about 4° north of the ecliptic — meant that it rose far to the northeast and some 30 minutes before the Sun set, despite the Moon being opposite the Sun. As such, even for the last shot, with the Moon several Moon diameters in altitude, the Sun was still up and lighting the landscape. In fact, at that time the Sun broke through clouds in the southwest to light the foreground with warm light. In this blend, the ground and majority of the sky comes from the final image with the highest Moon and warmest landscape lighting. For the earlier shots the Moon came up in a very bright sky. And so, to better represent the scene, some of the sky coloration — the magentas and cyans — comes from earlier exposures blended in with broad-brush masks. Dark anti-crepuscular rays also added subtle sky colouration and bands of darker blue. This is a sequence of 9 images at an interval of 2.5 minutes, extracted from a set of 80 frames taken every 15 seconds with the camera on automatic exposure, as the sky and ground remained bright enough for an accurate meter reading. The first 8 Moons are masked and layered in with a Lighten blend mode. All images were the Canon R5 at ISO 125 and Canon RF100-400mm lens at 281mm and f/8. Most processing in Adobe Camera Raw with ground and sky masks. Glow and dynamic contrast filters added with ON1 Effects plug-in.
Winter Full Moonrise in Crepuscular Rays
The rising Full Moon of January 6, 2023 over the Badlands of Horseshoe Canyon, near Drumheller, Alberta. Here the Moon is set in the pink Belt of Venus and with dark blue crepuscular rays (or more correctly, anti-crepuscular rays) converging on the point directly opposite the Sun. The rays are shadows 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. This night — and this year — the winter Full Moon (popularly called the Wolf Moon) was at a particularly high declination north of the ecliptic, about 4° above the ecliptic. So it rose more to the north than it normally would. This geometry is evident here in that the Moon lies well above (north of) the point where the shadows are converging to, which would be the position of the anti-Sun point on the ecliptic. This was the night of the Full Moon — in fact, the time of Full Moon almost exactly coincided with moonrise for me. However, the high declination of the Moon meant it rose about 30 minutes before sunset, so it rose into quite a bright sky, and was well up by the time the sky darkened enough to show these twilight colours. The next night the Moon, now a day past full, rose 30 minutes after sunset into a much darker sky. This is a single exposure with the Canon Ra and Canon RF70-200mm lens at 94mm. The red-sensitive Ra helps bring out the Belt of Venus colours. Most processing in Adobe Camera Raw with ground and sky masks. A mild glow layer added in Photoshop with the Radiant Photo plug-in.
Mars at Opposition in the Winter Sky
The red planet Mars in the winter sky lit by the waxing gibbous Moon, off frame at right. Mars is at centre, and nearly at its brightest for the year with it 4 days before its December 2022 opposition. It appears in Taurus, east of the Hyades and below the Pleiades, and above Orion. Sirius is rising at bottom just above the horizon. Procyon and Canis Minor is at lower left, with Castor and Pollux in Gemini above. At upper left is Capella in Auriga. The stars of Perseus at at top. Taken from home in Alberta, December 3, 2022, with the old rake as a foreground object. This is a stack of 4 images for the ground to reduce noise blended with one exposure for the sky, all 13 seconds at f/4 with the Canon RF15-35mm lens at 16mm, on the Canon R5 at ISO 800. All untracked on a fixed tripod. Diffraction spikes added for artistic effect with Astronomy Tools actions.
Red Moon in the Winter Sky (Nov. 8, 2022)
A wide-angle view of the total eclipse of the Moon of November 8, 2022, with the red Moon at right amid the stars of the northern winter sky and Milky Way, plus with bright red Mars at top. Above and left of the Moon is the blue Pleiades star cluster, while below it and to the left is the larger Hyades cluster with reddish Aldebaran in Taurus. The stars of Orion are left of centre, including reddish Betelgeuse, while at far left are the two Dog Stars: Procyon, at top, in Canis Minor, and Sirius, at bottom, in Canis Major. So this is a gathering of many red stars, planets and the rare red Moon. I shot the frames for this scene beginning at 3:50 am MST, 10 minutes before mid-totality during this 1h25m-long total eclipse. Some ice haze this night added the natural star glows. Either bands of airglow, or perhaps just reflected lights off the icy haze add the reddish bands to the sky. The sky scene appears over the old abandoned pioneer house on my property. This is a stack of 4 x 1-minute tracked exposures at ISO 1600 for the sky, blended with a single 1-minute tracked exposure at ISO 1600 for the ground to minimize blurring (I left the tracker running at the sidereal rate for all frames), plus a 5-second exposure for the Moon itself at ISO 400 to preserve the colouration of the disk and not overexpose it. However, I enlarged this short exposure Moon by 1.5x to cover up the overexposed Moon better and to better simulate the naked eye view where the eye and brain always thinks the Moon is much larger than the 0.5° it really is in the sky. A mild Orton glow added to the entire scene with Luminar Neo. All frames the Canon RF15-35mm lens at 16mm and f/2.8 on the Canon R5, and on the Star Adventurer tracker. Shot from home in southern Alberta on a night that we were lucky to have clear at all, as it had been snowing heavily all day. It cleared at night as predicted, but the temperature dropped to -25° C, so just operating gear was a chore, limiting my ambitions this night! And my travels. Snowy roads kept me home, but for once I didn't need to chase clear skies for a lunar eclipse.
Galaxy and glacier! The Milky Way over glacier-fed Lake Louise and Victoria Glacier in Banff National Park, Alberta. The Scutum Starcloud is just above and setting over Victoria Glacier, accompanied by star clusters in Serpens and Ophiuchus. Some airglow tints the sky above the mountains green and magenta. I shot this on a fine night on October 17, 2022 from the usual lakeshore promenade. Planning the timing of the shot was done with The Photographer's Ephemeris (TPE) and TPE3D. While an iconic picture-postcard scene by day, it is a challenge to shoot at night as lights from the Chateau Lake Louise behind the camera illuminate the foreground and the distant wooded mountainsides. This is a blend of two sets of exposures: - a stack of two untracked 2-minute exposures for the ground at ISO 800 - a stack of four tracked 1-minute exposures for the sky at ISO 1600 All with the Canon RF15-35mm lens at f/2.8 and 20mm and Canon R5, and with the camera and tripod not moving between image sets, and on the Star Adventurer Mini tracker. The reflected stars are trailed as they come from the untracked ground shots. Tracking reflected stars is very tough as it requires re-aligning the tracker to turn around the reflected celestial pole, in my case 51° below the horizon, not very practical. Panoramas stitched in Adobe Camera Raw and blended and masked in Photoshop. A mild Orton glow effect added to the sky with Luminar Neo and a ground enhancement effect added with Radiant Photo plug-in.
Galaxy and glacier! This is a vertical panorama of the Milky Way Galaxy over Lake Louise and Victoria Glacier in Banff National Park, Alberta. The Summer Triangle stars of Vega, Deneb and Altair are at centre. The Scutum Starcloud is just above and setting over Victoria Glacier. The dark lanes of interstellar dust — stardust! — weave among the bright star clouds of the Milky Way. I shot this on a fine night on October 17, 2022 from the usual lakeshore promenade. While a very iconic scene, it is a challenge to shoot at night as lights from the Chateau Lake Louise illuminate the foreground and even the distant wooded mountainsides. Some green and red airglow tints the sky along the horizon. This is a blend of three vertical panoramas: - the first is a set of three untracked 2-minute exposures for the ground at ISO 800 with the camera moved up by 15° from segment to segment; - the second shot immediately afterward is made of 7 x 1-minute tracked exposures at ISO 1600 for the sky, also moved 15° vertically from segment to segment; - elements of a third 3-section panorama taken about 90 minutes earlier during "blue hour" were blended in at a low level to provide better lighting on the distant peaks. All with the Canon RF15-35mm lens at f/2.8 and 20mm and Canon R5, and with the camera not moving between image sets, and on the Star Adventurer Mini tracker. The reflected stars are trailed as they come from the untracked ground shots. Tracking reflected stars is very tough as it requires re-aligning the tracker to turn around the reflected celestial pole, in my case 51° below the horizon, not very practical. Panoramas stitched in Adobe Camera Raw and blended and masked in Photoshop. A mild Orton glow effect added with Luminar Neo. Foreground and landscape enhanced with Radiant Photo plug-in.
Autumn Stars Rising at Lake Edith
The autumn constellations of Perseus and Cassiopeia above, with bright Capella in Auriga and the Pleiades star cluster in Taurus, at bottom, rising in the northeast over Lake Edith in Jasper National Park, on a clear autumn night. The Double Cluster is at centre, above the larger group of stars around Mirfak called the Perseus Association. This is a blend of a single tracked 2-minute exposure for the sky and water with the reflected stars, with a stack of two untracked 3-minute exposure for the rest of the ground, both at f/2.8 with the Canon RF15-35mm lens at 17mm and Canon R5 at ISO 1600. I shot this October 16, 2022. The tracker was the Star Adventurer Mini. The reflected stars are trailed not just because of the water movement but also because the tracker is following the stars in the sky, not the water. Having untrailed reflected stars would require polar aligning the tracker on the reflected celestial pole, in this case some 53° below the horizon due north. Mild Orton glows added with Radiant Photo and Luminar Neo.
The constellation of Ursa Major, the Great Bear, and the asterism of the Big Dipper low in the north over Lake Edith in Jasper National Park, on a clear autumn night. Arcturus is at left setting over Pyramid Mountain. Bands of airglow tint the sky, but also unfortunately, so does light pollution from the Park's service areas to the north of the townsite. This is a blend of a single tracked 2-minute exposure for the sky and water with the reflected stars, with a single untracked 4-minute exposure for the rest of the ground, both at f/2.8 with the Canon RF15-35mm lens at 17mm and Canon R5 at ISO 800. I shot this October 16, 2022. The tracker was the Star Adventurer Mini. A mild Orton glow effect added with Luminar Neo. Diffraction spikes on stars added with Astronomy Tools actions.
Northern Stars over Lake Edith
A panorama of the northern stars in autumn over and reflected in the calm waters of Lake Edith in Jasper National Park, in the deep twilight. The Big Dipper and Ursa Major are at left, with Arcturus over Pyramid Mountain at far left. Capella is rising at right, and above it are the stars of Perseus and Cassiopeia. This was on a very clear mid-October night in 2022. This is a blend of two panoramas: a 4 x 1-minute tracked panorama for the sky at ISO 800, and a 4 x 2-minute untracked panorama taken immediately afterwards at ISO 1600, all with the Canon RF15-35mm lens at f/2.8 and 15mm, on the Canon R5. Stitched in Adobe Camera Raw. A mild Orton glow effect added with Luminar Neo. The tracker was the Star Adventurer Mini.
Northern Stars over Lake Edith in Twilight
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. This is a panorama of four segments, each 30 seconds untracked with the Canon RF15-35mm lens at 15mm and f/2.8 and Canon R5 at ISO 1000. Stitched with Adobe Camera Raw.
Athabasca River at Moonrise Panorama
A panorama of the glacier-fed Athabasca River and peaks around Mount Fryatt in Jasper National Park, as the Milky Way is setting and the waning gibbous Moon rising, lighting the peaks of the Continental DIvide with lunar alpenglow. Mount Fryatt is at centre, while to the right is Mount Geraldine, and to the left are Brussels Peak and Mount Christie. Jasper is one of the world's largest Dark Sky Preserves. I shot this on a fine night on October 15, 2022 from the "Goats and Glaciers" Viewpoint on the Icefields Parkway. Jupiter, large and fuzzy in some thin cloud, is at far left, while Saturn is left of centre over Mount Christie. The bright area in the Milky Way over Mount Fryatt is the Scutum Starcloud. Altair is the bright star at top. Some green airglow tints the sky at left, while some red airglow or possibly low-level aurora tints the sky at right. The location is called Goats and Glaciers because mountain goats are often here enjoying the salt lick deposits. This is a blend of three 3-section panoramas: - the first taken with a Star Adventurer Mini for 3 x 2-minute tracked exposures for the sky at ISO 800; - the second immediately afterward with the tracker off for 3 x 3-minutes at ISO 800 for the ground; - and the third taken about an hour later as the Moon rose, lighting the peaks with warm light, for 3 x 2.5-minutes at ISO 1600. All with the Canon RF15-35mm lens at f/2.8 and 15mm and Canon R5, and with the camera not moving between image sets . So this is a time blend, combining frames taken an hour apart, to retain the dark sky with the Milky Way before moonrise, blended with the alpenglow at moonrise. However, most of the landscape comes from the earlier panorama lit only by starlight. Panoramas stitched in Adobe Camera Raw and blended and masked in Photoshop.
Big Dipper Over Pyramid Mountain at Moonrise
The stars of the Big Dipper over the iconic peak of Pyramid Mountain from Pyramid Island, a popular location in Jasper National Park, Alberta, for nightscape and aurora photography. This was on a very clear night in mid-October, 2022, with many aspen stands still in full autumn colour. The images for this scene were shot at moonrise, with the waning gibbous Moon off frame at right lighting the sky blue and landscape with warm alpenglow moonlight. As bonus, a short bright meteor and its orange "smoke" trail appeared on the sky exposures. I shot this during the first weekend of the 2022 Jasper Dark Sky Festival, and so there were quite a few people on the island and around Pyramid Lake this night enjoying the stars on this mild autumn night. This is a blend of: a stack of 4 x 1-minute tracked exposures for the sky at ISO 1600 plus a stack of 6 x 3-minute untracked exposures at ISO 800 for the ground, all with the Canon RF15-35mm lens at 20mm and f/2.8 and Canon R5. The tracker was the Star Adventurer Mini. The tracked exposures were shot first, followed immediately by the untracked ground exposures timed to catch the alpenglow lighting of the mountain and trees. I enhanced the landscape slightly with the Radiant Photo plug in and added a mild Orton glow with Luminar Neo. Noise reduction was with ON1 NoNoise AI.
The summer Milky Way over and reflected in the relatively calm water of Pyramid Lake in Jasper National Park, on a mid-October night. The Jasper Sky Tram adds the lights on Whistler Peak. Bands of airglow tint the sky with red. Lights from the Jasper townsite, still mostly unshielded sodium vapour lights as of 2022, add the skyglow at left. Altair is the bright star at top. The red Lagoon Nebula is just setting behind the mountain skyline. The slight wind rippled the water enough to prevent a perfect reflection. I shot this during the first weekend of the 2022 Jasper Dark Sky Festival, and so there were quite a few people on the island, and next to me at this spot, and around Pyramid Lake enjoying the stars on this mild autumn night. This is a blend of: a stack of 4 x 1-minute tracked exposures for the sky at ISO 1600 plus a stack of 7 x 2-minute untracked exposures at ISO 800 for the ground, plus an additional single 1-minute tracked exposure for the reflected stars and the foreground water. All were with the Canon RF15-35mm lens at 15mm and f/2.8 and Canon R5. The tracker was the Star Adventurer Mini. The tracked exposures were shot first, followed immediately by the untracked ground exposures. I enhanced the landscape slightly with the Radiant Photo plug in and added a mild Orton glow with Luminar Neo. Noise reduction was with ON1 NoNoise AI.
Mount Cephren at Lower Waterfowl Lake, in the light of the low waning Moon lighting the peaks but not the foreground. This is from the lakeside viewpoint on the Icefields Parkway in Banff National Park, Alberta. I shot this on a very clear night October 13, 2022. There was enough wind to ripple the water and blur any stellar reflections. The Milky Way is to the left of Cephren, but is being lost in the brightening moonlit sky. This is a blend of 5 x 20-second exposures stacked for the ground to smooth noise, and a single 20-second exposure for the sky, all with the Canon RF15-35mm lens at f/2.8 and Canon R5 at ISO 1600. All were untracked camera-on-tripod shots. ON1 NoNoise AI applied to the single sky image for noise reduction. A mild Orton glow added with Luminar AI.
This is a panorama of Peyto Lake in Banff National Park, on the Icefields Parkway in Alberta, taken at moonrise on a very clear and mild mid-October evening. The glacier-fed lake appears its characteristic blue even when lit by starlight. It is not blended in from an earlier "blue hour" shot. To the southwest at left is the summer Milky Way over Peyto Glacier and Peyto Peak. To the west at centre is Arcturus setting over Caldron Peak, while to the north at left of centre are the stars of the Big Dipper and Ursa Major. At far right, in the blue moonlit sky, is Perseus and the autumn Milky Way. At far left over the walkway is Saturn in Capricornus. Magenta airglow tints the northern sky and nicely frames the peaks, which are lit by golden lunar alpenglow, warm light from the rising waning gibbous Moon behind the peaks at right to the east. This is an example of a "moonstrike" image; the timing was perfect this night to catch the mix of Milky Way and alpenglow. I was the only one there that night to enjoy the view, and occupy the prime spot at the end of the new viewpoint. This is a blend of two panoramas: the first of the sky taken at or just before moonrise with the camera on a star tracker to keep the stars pinpoint, and the second taken for the ground about 20 minutes later with the tracker off, when the Moon was up high enough to light the peaks of the Continental Divide west of Peyto Lake. Both pans were with the Canon RF15-35mm lens at 15mm and f/2.8, and Canon R5 at ISO 1600, with the sky pan being 6 segments for 1 minute each, and the untracked ground panorama being the same 6 segments for 2 minutes each, but with LENR on to subtract thermal noise hot pixels from the image, something the R5 is prone to. Stitched with Adobe Camera Raw and masked and blended in Photoshop. Noise reduction was with ON1 NoNoise AI, and foreground enhancement with the Radiant Photo plug-in, plus with a mild Orton glow added mostly to the sky with Luminar Neo.
The Great Bear over Peyto Lake
The stars of Ursa Major, the Great Bear, over the waters of Peyto Lake, Banff, in deep twilight. Arcturus in Böotes, the Bear Driver, is setting over the peak at left. Ursa Major contains the seven stars that make up the Big Dipper, aka the Plough or the Wagon. This was October 13, 2022 on a very clear night in the Rocky Mountains. This is a stack of 6 x 30-second exposures for the ground and a single untracked 30-second exposure for the sky, all at f/2.8 with the Canon RF 15-35mm lens at 15mm, and Canon R5 at ISO 800.
Reflected Moonrise Over Prairie Lake (Composite)
The rising of the Full "Hunter's Moon" of October 9, 2022, with the Moon reflected in the calm waters this night at Crawling Lake Reservoir in southern Alberta. The Moon appeared very pink as it rose into the clear sky near the horizo, then turned more yellow as it rose into scattered bands of cloud. This serves as a goo demo of the Moon illusion and how the Moon does not change size as it rises — it is the same size on the horizon as it is higher up. This is a blend of 10 images taken 3 minutes apart with the RF70-200mm lens at 200mm and Canon R5, each frame exposed for the Moon. The frames were blended onto the first image (which contributes the lowest Moon and all the sky and foreground) in Photoshop using a Normal blend mode but with Blend If sliders and masks to isolate the later moons and reflected moons. There is also a single-image version of this scene.
