Nebulas and Clusters Around the Small Sagittarius Starcloud

This is an impressive area of sky rich in bright and dark nebulas and open star clusters in Sagittarius and Serpens. This is closeup of the Small Sagittarius Starcloud, aka Messier 24, at bottom right, with the field extending north to include the nebulas M17, the Swan Nebula, and M16 at top right, the Eagle Nebula. Between M17 and M24 is the small star cluster M18. Patches of red and blue nebulosity at bottom right below M24 are IC 1283 and the blue reflection nebulas NGC 6589 and 6590. The prominent dark nebula at the right (west) edge of the Starcloud is Barnard 92 with its lone star embedded in it, with smaller B93 above it. At the left are the star clusters M25 (bottom) and NGC 6645, with the large dark nebula B312 above. This is a stack of 3 x 6-minute exposures with the William Optics RedCat 51mm astrograph at f/5 and the Canon EOS Ra at ISO 800 with LENR on as it was the warmest night of the summer, August 17, 2020. Aligned, stacked and mean combined in Photoshop. Autoguided with the ZWO ASIAir and ASI120MM guide camera with the RedCat on the Astro-Physics Mach1 mount. No filters employed here. Clouds thwarted more exposures.

North America Nebula NGC 7000 in Cygnus

The often-photographed (certainly by me) area of the North America Nebula, NGC 7000, near the bright star Deneb, which is in the frame at right, in Cygnus. The Pelican Nebula, IC 5067/70 is right of the North America, in the “Atlantic Ocean” so to speak. The nebulosity at bottom is the “Cygnus Arc,” IC 5068. The small patch of blue reflection nebulosity at top is IC 5076. The patches of dark nebulosity above the North America Nebula are B352 and B356. This is a stack and blend of: four exposures without a filter, each 8 minutes at ISO 800, and four exposures with an Optolong L-Enhance nebula filter to bring out the faintest nebulosity, each 16 minutes at ISO 1600. These are blended in with a Lighten mode. All were with the William Optics RedCat 51mm astrographic refractor at its native f/5 and Canon EOS Ra camera, the factory filter-modified camera capable of recording this type of hydrogen-alpha emitting nebulas. Guided with the ZWO ASIAir and ASI120MM guide camera, on the Astro-Physics Mach1 mount. Taken from home on a perfect summer night on August 15, 2020.

Comet NEOWISE at Columbia Icefields (July 27, 2020)

Comet NEOWISE (C/2020 F3) on July 27, 2020 from the Columbia Icefields (Jasper National Park, Alberta) from the Toe of the Glacier parking lot, looking north over Sunwapta Lake, formed by the summer meltwater of Athabasca Glacier. So this is a portrait of ice in the sky and icy water on Earth. This was 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! While it was pale to the eye, the long expposure of the camera did pick up the blue ion and white dust tails very well. The ion tail extends about 15° and the dust tail at least 10°. The tails are certainly more prominent than in 99% of any comets we see any given year! So this was still a nice comet! Red and green bands of airglow, some faint magenta aurora on the horizon, and some lingering blue perpetual twilight at his northern latitude all tint the sky. The Big Dipper stars are at top. Arcturus is at far left. The orange star at bottom is Tania Australis, here made a little larger by it shining through some thin haze. This is an exposure blend of a stack of 4 x 4-minute untracked exposures for the ground, with 4 x 2-minute tracked and stacked exposures for the sky. Stacking the images smooths noise. Tracking the sky prevents star trailing in the long exposures required to reveal the faintest stars and the subtle comet tails. The camera was on the iOptron SkyGuider Pro tracker. For the ground shots I simply turned the tracker motor off. All with the 24mm Sigma Art lens at f/2.8 and Canon EOS Ra at ISO 1600 for the ground and ISO 3200 for the sky. 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. The foreground is lit in part by lights from the Icefields Centre buildings off camera to the right.

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.

Comet NEOWISE and Big Dipper Over Badlands (July 22, 2020)

Another incredible sky this night! This is Comet NEOWISE (C/2020 F3) over the badlands formations at Dinosaur Provincial Park, Alberta on July 22-23, 2020, with the Big Dipper above. A very active thunderstorm system moving northeastward this night but well to the west of me lights the horizon. Parallel bands of red and green airglow tint the sky, as does the blue of lingering summer twilight. Even with the bright sky the comet’s blue ion tail can be traced up to and past the Bowl of the Big Dipper. This is an exposure blend, with the landscape from a stack of seven exposures from 2.5 to 3.5 minutes long at f/2.8 and ISO 1600, stacked to smooth noise, blended with a single untracked 30-second exposure for the sky at ISO 6400 at f/2, all with the Sigma 24mm lens and Canon EOS Ra camera. The ground is illuminated by starlight and sky light only; no light painting was used here. Topaz DeNoise AI applied to the sky; Sharpen AI applied to the ground. Some light sculpting applied to the ground with a Dodge and Burn layer and a luminosity mask, to make the foreground less flat in lighting.

Comet NEOWISE Over Dinosaur Park (July 15, 2020)

This is Comet NEOWISE (C/2020 F3) over the badlands and formations of Dinosaur Provincial Park, Alberta, on the night of July 14-15, 2020, at about 12:30 am local time with it nearly due north and as low as it got for the night at this latitude of 51° N. A green and magenta aurora colours the northern sky also blue with perpetual summer twilight. Capella is at far right. The comet’s dim blue ion tail is visible here extending some 18° to the top of the frame; the whitish curving dust tail extends about 12° though it becomes lost in the sky still bright with twilight and the aurora this night. This is a classic comet! Very much the dimmer twin of Comet Hale-Bopp from April 1997. This is a blend of 6 exposures for the ground stacked to smooth noise, with a single exposure for the sky, with the 35mm Canon lens and Canon 6D MkII. The ground exposures are 1- and 2-minutes at ISO 1600 and f/2.8, while the single untracked sky exposure was 20 seconds at ISO 3200 and f/2.5. There was no Moon, thus the need to take very long exposures for the ground to reveal details in the landscape here illuminated by just starlight and the faint aurora that was to the north and that was barely visible to the eye. Otherwise the ground would have been a featureless silhouette. So, yes, this image shows much more than the eye could see unaided due to the long exposures, but that’s the point and attraction of astrophotography — to record celestial objects and scenes with more detail than the eye can see. Indeed, any exposure longer than a second is bound to show more than the eye can detect. However, in binoculars the ion tail was barely visible, helped by knowing it was there. But the dust tail could be see to this extent, but in binoculars! However, the comet was still a fine sight naked eye, with an obvious tail about 5° to 6° long to the eye, despite the bright midnight sky. LENR employed in camera on all shots this warm night to remove thermal speckling and colour casts the 6D MkII is prone to. Stacked and masked with Photoshop. Topaz DeNoise AI applied to the sky; Topaz Sharpen applied to the ground, plus a mild touch of ON1 Photo RAW Dynamic Contrast.

Panorama of Comet NEOWISE Over Prince of Wales Hotel (July 14, 2020)

A once-in-a-lifetime scene — A panorama of the dawn sky at 4 am on July 14, 2020 from Waterton Lakes National Park, Alberta, Canada with Comet NEOWISE (C/2020 F3) over the iconic Prince of Wales Hotel. Noctilucent clouds glow below the comet in the dawn twilight. Venus is rising right of centre paired with Aldebaran and the Hyades star cluster, while the Pleiades cluster shine above. The waning quarter Moon shines above the Vimy Peak at far right. The Big Dipper is partly visible above the mountain at far left. Capella and the stars of Auriga are at centre. This is an 8-segment panorama with the 35mm Canon lens at f/2.5 for 15 seconds each at ISO 100 with the Canon 6D MkII and stitched with Adobe Camera Raw.

Comet NEOWISE and Aurora Panorama (July 13, 2020)

Another amazing sky scene — A panorama of the late night sky just before midnight on July 13, 2020 from Waterton Lakes National Park, Alberta, Canada with Comet NEOWISE (C/2020 F3) over the front range of the Rocky Mountains and an arc of aurora across the north. Earlier, noctilucent clouds were also visible. Quite the show! This was taken from the Bison Compound access road. This is an 6-segment panorama with the 35mm Canon lens at f/2.2 for 25 seconds each at ISO 800 with the Canon 6D MkII and stitched with Adobe Camera Raw.

Comet NEOWISE over Red Deer River

Comet NEOWISE (C/2020 F3) over the Red Deer River from Orkney Viewpoint north of Drumheller, Alberta, on the morning of July 11, 2020. The sky is brightening with dawn twilight and a small display of noctilucent clouds is on the horizon at right. The constellation of Auriga with the bright star Capella is at right. This is looking north toward the Bleriot Ferry terminal. Light from the waning gibbous Moon provides the illumination, plus twilight. Some ground fog lies in the valley below. This is a two-segment vertical panorama with the 35mm Canon lens at f/2.8 and Canon 6D MkII at ISO 200 for 13 seconds each. Stitched with Adobe Camera Raw with Perspective geometry.

Comet NEOWISE over Red Deer River Panorama (July 11, 2020)

What a magical scene this was! This is Comet NEOWISE (C/2020 F3) over the sweep of the Red Deer River and Badlands from Orkney Viewpoint north of Drumheller, Alberta, on the morning of July 11, 2020. The sky is brightening with dawn twilight and a small display of noctilucent clouds is on the horizon right of centre. Venus and and Pleiades are rising at right. Venus was close to the star Aldebaran and in the Hyades star cluster, both just visible right on the horizon. This is looking north toward the Bleriot Ferry terminal. Light from the waning gibbous Moon provides the illumination, plus twilight. This nicely shows the arch of the twilight colours. This is a 6-segment panorama with the 50mm Sigma lens at f/2.8 and Canon 6D MkII at ISO 400 for 13 seconds each. Stitched with Adobe Camera Raw. Topaz DeNoise AI and Sharpen AI applied.

The Cygnus Starcloud and Nebulosity

This is the central area of Cygnus and its bright Milky Way starcloud surrounded by red nebulosity. At left is the star Sadr (gamma Cygni) with the complex of nebulosity catalogued as IC 1318. At centre is the distinct Crescent Nebula, NGC 6888, a expanding nebula created by winds from a hot Wolf-Rayet star. At bottom left is the star cluster Messier 29, though looking a little lost in the rich starfields here. At top is the cluster IC 1311, looking more obvious than M29 but not observed visually and included in the NGC catalog. Odd. At far right are the large and loose star clusters NGC 6883 and NGC 6871, the latter an obvious binocular sight. To the left of Sadr is the small cluster NGC 6910. The dark nebulas B145 and LDN 862 are at right. The small emission nebula at bottom is Sharpless 2-104. This is a stack of 6 x 6-minute exposures at ISO 1600 without a filter, blended with 8 x 12-minute exposures at ISO 3200 taken through the Optolong L-Enhance dual narrowband filter to really bring out the faint nebulosity. All were with the William Optics RedCat 51mm f/5 astrograph and red-sensitive Canon EOS Ra full-frame mirrorless camera. Blending the two sets of exposures brings out the nebulosity while retaining the more natural colours in the stars and background sky. All stacked, aligned and blended in Photoshop CC. Taken from home in the wee hours of the morning of May 15/16, 2020 before dawn’s light began to wash out the sky.

Nebulas and Clusters in Gemini and Orion Mosaic

This is a two-panel mosaic of nebulas and clusters in southern Gemini and northern Orion. The Messier 35 star cluster is at top accompanied by the smaller cluster NGC 2158. At left near the orange star Eta Geminorum is the crescent-shaped Jellyfish Nebula, IC 443, a supernova remnant. The fainter, diffuse nebula at far left is IC 444. At bottom and over the border in Orion is the Monkeyhead Nebula, NGC 2174. The little round nebula above NGC 2174 is Sharpless 2-247. This is a mosaic of two segments for the northern and southern halves of the scene, with each half being a stack of 6 x 8-minute exposures at ISO 800 with no filter, plus a stack layered in of 6 x 8-minute exposures at ISO 3200 with an Optolong L-Enhance filter to bring out the faint red nebulosity. So this is a stack and blend of a total of 24 exposures. Alll were with the Canon EOS Ra camera on the SharpStar HNT150 Hyperbolic Newtonian astrograph at f/2.8.

The Orion and Running Man Nebulas

The Orion Nebula, aka Messier 42, at centre, with the blue Running Man Nebula (NGC 1973-5-7) above it. The smaller nebula attached to the top edge of M42 is M43. The blue star cluster at top above the Running Man is NGC 1981; the loose star cluster below M42 is NGC 1980. This is a stack of 8 x 5-minute exposures with the Canon EOS Ra mirrorless camera at ISO 800 unfiltered, blended with a stack of 6 x 8-minute exposures at ISO 1600 but through the dual-band Optolong L-Enhance filter that records the faint red nebulosity very well. Blending and masking the filtered with the unfiltered shots allows the faint red nebulosity to come through while retaining the blues, magentas and even subtle greens of the bright nebulosity and the blue of the hot stars as recorded by the “white-light” images. These two sets of long exposures are blended using luminosity masks with a set of 6 x 60-second exposures and 4 x 30-second exposures, both at ISO 400, for recording the bright core of M42 with its Trapezium stars that would otherwise be overexposed into a bright mass with only long exposures. The short exposures were all unfiltered. I applied a high-pass sharpening filter to snap up contrast in the dark lanes. All were through the SharpStar HNT150 Hyperbolic Newtonian Astrograph at its native fast focal ratio of f/2.8. for a focal length of 420mm. Taken from home January 28, 2020. All stacked, aligned and blended in Photoshop 2020. PS’s Auto-Align function aligned all 24 images in one fell swoop in less than a minute.

The Horsehead Nebula and Orion's Belt

This is the Belt of Orion with its three blue stars across the top of the frame (L to R: Alnitak, Alnilam, and Mintaka), with the iconic Horsehead Nebula (aka B33) below Alnitak, with the dark Horsehead set against the bright nebula IC 434, aka Orion’s Dagger. The pinkish nebula above Alnitak is NGC 2024, the Flame Nebula. The small blue reflection nebula left of the Horsehead is NGC 2023, with smaller IC 435 to the left of it. The field is filled with the large open cluster Collinder 70. The multiple star at bottom left of centre is Sigma Orionis. Many other smaller bits of reflection nebulas populate the field in and around the Belt. This is a blend of 8 x 5-minute exposures at ISO 800 unfiltered with 6 x 10-minute exposures at ISO 1600 shot through an Optolong L-Enhance dual-band nebula enhancement filter (it lets through only Oxygen III blue-green and Hydrogen-alpha red to really enhance the nebulosity). The filtered shot is blended in with the unfiltered shot to retain the best of both worlds: the rich reds captured by the filtered images without losing the range of colours in the other nebulas such as the salmon pinks of the Flame and the blue reflection nebulas and stars. All exposures with the Canon EOS Ra mirrorless camera through the SharpStar HNT150 Hyperbolic Newtonian Astrograph at f/2.8, from home on a very clear moonless night January 27, 2020. All stacked, aligned and blended in Photoshop 2020.

The Cone Nebula and Christmas Tree Cluster of Monoceros

This is the nebula rich region in the constellation of Monoceros the Unicorn with the dark Cone Nebula (left of centre) and the small V-shaped and bright Hubble’s Variable Nebula at bottom, a reflection nebula that varies in form and brightness. Above the Cone Nebula is the triangular Christmas Tree Cluster, NGC 2264, here upside down as the bright blue star 15 Mon is the base of the tree. The large region of nebulosity is Sharpless 2-273. The V-shaped dark nebula above centre is LDN 1603. Near 15 Mon is a blue reflection nebula. Another blue reflection nebula IC 2169 and associated star cluster Collinder 95 is at left — I framed the field to contain this nebula. Other bits of reflection nebulosity surround it - clockwise: NGC 2245, NGC 2247 and IC 446 above the main nebula. The rich faint cluster near centre is Trumpler 5. This is a blend of 8 x 5-minute exposures at ISO 800 unfiltered with 6 x 8-minute exposures at ISO 1600 shot through an Optolong L-Enhance dual-band nebula enhancement filter (it lets through only Oxygen III blue-green and Hydrogen-alpha red to really enhance the nebulosity). All exposures with the Canon EOS Ra mirrorless camera through the SharpStar HNT150 Hyperbolic Newtonian Astrograph at f/2.8, from home on a very clear moonless night January 26, 2020. All stacked, aligned and blended in Photoshop 2020.

Messier 38 and the Flaming Star Nebula in Auriga

This is the rich region in the centre of the constellation of Auriga with the Flaming Star Nebula, IC 405 at right, and the roundish IC 410 at bottom with the cluster NGC 1893. At top left is the star cluster Messier 38, with small NGC 1907 below it. The small nebula at left is IC 417 around the loose cluster Stock 8. The large elongated nebula at top is Sharpless 2-230. The colourful asterism of stars between IC 405 and IC 410 is the Leaping Minnow or Little Fish, aka Mel 31. This is a blend of 8 x 4-minute exposures at ISO 800 unfiltered with 8 x 8-minute exposures at ISO 2000 shot through an Optolong L-Enhance dual-band nebula enhancement filter (it lets through only Oxygen III blue-green and Hydrogen-alpha red to really enhance the nebulosity). Blending the exposures adds the extensive red nebulosity recorded by the filtered images without turning the whole field — and stars — red and losing the blue reflection nebulas and subtle colour variations even in the red Ha nebulas. All exposures with the Canon EOS Ra mirrorless camera through the SharpStar HNT150 Hyperbolic Newtonian Astrograph at f/2.8, from home on a very clear moonless night January 24, 2020. All stacked, aligned and blended in Photoshop 2020. High pass sharpening applied as well as a very selective use of frequency separation sharpening with WOW Freq Equalizer extension.

Star Clusters and Nebulas in Auriga

A collection of bright star clusters and colourful nebulas in central Auriga. Messier 36, aka the Pinwheel Cluster, is at far left. Messier 38, aka the Starfish Cluster, is at top left, with the small cluster NGC 1907 below it. The large nebula at right is IC 405, the Flaming Star Nebula surrounding and extending from the star AE Aurigae. The part of the nebula around the star is blue reflection nebulosity. The large nebula at bottom is IC 410 surrounding a loose star cluster NGC 1893. The small nebula left of centre is IC 417. The smaller nebula between IC 417 and Messier 36 is NGC 1931. The colourful group of stars between IC 405 and 410 at right is the Little Fish asterism. This is a stack of 8 x 8-minute exposures through the Borg 77mm f/4 astrograph and with the Canon EOS Ra red-sensitive mirrorless camera, at ISO 800. Stacked, aligned and processed in Adobe Camera Raw and Photoshop 2020. No nebula or light pollution reduction filter was employed in taking the images. I shot this from home November 25, 2019 on a very fine if frosty autumn night. The Dew Destroyer heater coil from David Lane wrapped around the front objective nicely kept off the frost. As the temperature was -10° C, I did not employ Long Exposure Noise Reduction or take and apply dark frames.

Clusters and Nebulas on the Cassiopeia-Cepheus Border

A collection of bright star clusters and colourful nebulas on the border of Cassiopeia and Cepheus. The prominent star cluster at left is Messier 52. The emission nebula to the lower right of it is NGC 7635, aka the Bubble Nebula; above and to the right of it is the small but intense nebula NGC 7538. At upper right of the frame is Sharpless 2-155, aka the Cave Nebula. The diffuse nebula at bottom is Sharpless 2-157, aka the Lobster Claw Nebula, with the small star cluster NGC 7510 near the end of one of its claws. The small star cluster at lower right made yellow by interstellar dust absorption is NGC 7419. This is a stack of 8 x 8-minute exposures through the Borg 77mm f/4 astrograph and with the Canon EOS Ra red-sensitive mirrorless camera, at ISO 800. Stacked, aligned and processed in Adobe Camera Raw and Photoshop 2020. No nebula or light pollution reduction filter was employed in taking the images. I shot this from home November 25, 2019 on a very fine if frosty autumn night. No special star masks were employed in processing to enhance star colours or process them separately.

Aurora Panorama from ms Trollfjord

A 180° panorama from the deck of the Hurtigruten ship the ms Trollfjord, looking northward toward the Northern Lights, as friends Dave and Christine at right gaze at the aurora. This was October 19, 2019, southbound from the coast of Norway north of Tromsø and south of Skjervøy. The Kp Index was 1 to 2 this night. The waning gibbous Moon is low in the southeast at right, lighting the seascape. The Big Dipper and due north is at centre. West is to the left; east to the right. This is a 9-segment panorama with the 15mm lens at f/2 and Sony a7III at ISO 6400 for 0.6 second each and stitched with Adobe Camera Raw.

Aurora over Cameron River with Autumn Colours

The Northern Lights in an arc across the northern sky over the Cameron River, downriver from the Ramparts Falls. This was September 8, 2019 with the trees turning in their fall colours. The Big Dipper at top centre. This is a two-segment panorama, each 25 seconds at f/2 with the Laowa 15mm lens and Sony a7III at ISO 800. Stitched with ACR.

Panorama of the Aurora Dancing over Yellowknife

This is a 300° panorama of the Northern Lights over Yellowknife, NWT on the night of Sept 6-7, 2019, during a sub-storm outbreak at 12:45 a.m. when the sky went wild with aurora. There were curtains and rays everywhere. The display soon subsided into a general wash over the sky. This is from Pilot’s Monument lookout in Old Town. South is left of centre; East is at far left; West is right of centre, and North is at far right, with the Big Dipper visible. Taurus and the Pleiades are rising at far left. This is a 9-segment panorama with the 15mm Laowa lens at f/2 and Sony a7III at ISO 800, for 10 seconds each. LENR employed in camera. Stitched with ACR.

Aurora Panorama from Grasslands (Aug 26, 2019)

A panorama of the arc of Northern Lights seen August 26, 2019 about 11:30 p.m. CST from Grasslands National Park, Saskatchewan, from the Two Trees Road. This is looking northeast. The Big Dipper is at far left. Capella is the bright star above the arc, while Perseus is at upper right. The Pleiades are rising at right, above the silhouette of 70 Mile Butte. This was a diffuse grey arc to the eye but the camera picks up the green and red colours from the oxygen emission lines. This is a 5-segment panorama with the 24mm Sigma Art lens at f/2 and Nikon D750 at ISO 3200 for 20 seconds each. Stitched with Photoshop.

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.
