  • An extensive display of noctilucent clouds blended with a star trail sequence of the circumpolar stars of the northern sky. <br />
<br />
This is a stack of thirty 30-second exposures taken at the end of a sequence of 450 shots, taken when the sky was darkest with the most stars visible, blended with a shorter exposure taken earlier in the night when the noctilucent clouds were more extensive across the twilight sky. So this is a "time-blend" of frames taken from a set shot for a time-lapse. <br />
<br />
All with the TTArtisan 11mm full-frame fish-eye lens at f/2.8 and on the Canon R6.

  • A star trail image with the main trails at centre of Jupiter (brightest) and below it dimmer Saturn setting together in the southwest twilight sky on January 3, 2021. Stars add the other trails above in the darker sky from the later frames in the sequence. This was more than 10 days after their very close Great Conjunction, though the two planets were still quite close in the evening sky.<br />
<br />
This is a stack of 950 frames taken over 45 minutes at 2-second intervals with manually increased exposure time throughout. All with the 85mm Rokinon lens at f/4 and Canon 6D MkII at ISO 100. Stacking was direct from the developed raw files with the now sadly discontinued Advanced Stacker Actions Plus action set. Processing was with LRTimelapse to equalize and ramp the settings to smooth the transitions for the purposes of a time-lapse movie. The ground and band of dark clouds are from a stack of 10 frames from early in the sequence when it was brighter, stacked to smooth noise.

  • A composite showing me (on the right lit in green) and fellow Calgary RASC astronomy club members pointing at Polaris with green laser pointers at a public star party July 27, 2019 at the Rothney Astrophysical Observatory. About 600 people attended this night. I was presenting a laser-guided tour of the night sky.<br />
<br />
The stack of sky images shows the circumpolar sky rotation around Polaris. The sky at right is bright from light pollution from Calgary.<br />
<br />
This is a stack of 200 images for the rotating sky and star trails, plus a single exposure for the image with the laser beams and people, with an average stack of 8 exposures blended in for the foreground to smooth noise. All exposures 6 to 8 seconds at f/2 and ISO 3200 with the Venus Optics 15mm lens and Sony a7III, taken as part of a 1200-frame time lapse. Stacked with Advanced Stacker Plus actions in Photoshop.

  • The eroding formations of Dinosaur Provincial Park, Alberta, lit by the rising gibbous Moon, off camera at right, on April 21/22, 2019. This is looking north, with the stars of the northern sky pivoting around Polaris. <br />
<br />
This is a stack of 8 exposures, mean combined to smooth noise, for the ground, and 250 exposures for the sky, blended with Lighten mode to create the stails. However, I used the Advanced Stacker Plus actions in Photoshop to do the stacking, creating the tapering effect in the process.  <br />
<br />
All exposures with the 15mm Laowa lens at f/2.8 and Sony a7III at ISO 3200, each for 30 seconds. Luminar Flex effects Soft Glow added to the sky and Autumn Colors added to the ground.

  • The Sun setting into a pall of forest fire smoke over Alberta from fires in B.C. and elsewhere, on August 17, 2018. This shows the dimming and reddening of the Sun as it set, with it disappearing from view long before it reached the horizon.<br />
<br />
This was from home in southern Alberta, and is a Lighten blend mode stack of 20 images taken at 10 minute intervals, and shot on Auto Exposure with the Canon 6D MkII and 35mm lens. The frames are part of a larger 200-frame timelapse processed with LRTimelapse.

  • A blend of images to show the stars of the southern sky moving from east to west (left to right) over the peaks of the Continental Divide at Herbert Lake near Lake Louise, in Banff, Alberta. The main peak at left is Mount Temple. <br />
<br />
A single static image shows the Milky Way and stars at the end of the motion sequence.<br />
<br />
The star trails and Milky Way reflect in the calm waters of the small Lake Herbert this night on July 17, 2018.<br />
<br />
This is a stack of 100 images for the star trails, stacked with the Long Streak function of Advanced Stacker Plus actions, plus a single exposure taken a minute or so after the last star trail image. The star trail stack is dropped back a lot in brightness, plus they are blurred slightly, so as to not overwhelm the fixed sky image. <br />
<br />
The sky images are blended with a stack of 8 images for the ground, mean combined to smooth noise in the ground. <br />
<br />
All are 30 seconds at f/2.8 with the 24mm Sigma lens and Nikon D750 at ISO 3200. All were taken as part of a time-lapse sequence. Clouds moving in added the odd dark patches in the Milky Way that look like out of place dark nebulas. <br />
<br />
The reflected star trails are really there in the water and have not be copied, pasted and inverted from the sky image. They look irregular because of rippling in the water.

  • A blend of images to show the stars of the southern sky moving from east to west (left to right) over the Rocky Mountains at Bow Lake, in Banff, Alberta. The main peak at centre is Bow Peak. Crowfoot Glacier is at far left; Bow Glacier is at right below the Milky Way. <br />
<br />
A single static image shows the Milky Way and stars at the end of the motion sequence.<br />
<br />
The star trails and Milky Way reflect in the calm waters of Bow Lake this night on July 16, 2018, though they appear large and out of focus.<br />
<br />
This is a stack of 300 images for the star trails, stacked with the Ultrastreak function of Advanced Stacker Plus actions, plus a single exposure taken a minute or so after the last star trail image. The star trail stack is dropped back a lot in brightness, plus they are blurred slightly, so as to not overwhelm the fixed sky image. <br />
<br />
The sky images are blended with a stack of 8 images for the ground, mean combined to smooth noise in the ground. <br />
<br />
All are 30 seconds at f/2 with the 15mm Laowa lens and Sony a7III at ISO 3200. All were taken as part of a time-lapse sequence. Bands of airglow add the green streaks to the sky.

  • The stars trailing as they move east to west (left to right), ending with the Milky Way and Galactic Centre (right) over Storm Mountain and the Vermilion Pass area of the Continental Divide in Banff National Park, Alberta. Mars is the bright trail at left. Saturn is amid the Milky Way at right. <br />
<br />
This was July 15, 2018. The lights at left are from the Castle Mountain interchange at Highways 1 and 93.<br />
<br />
This is a stack of 8 exposures, mean combined to smooth noise, for the ground, plus 200 exposures for the star trails, and one exposure, untracked, for the fixed sky taken about a minute after the last star trail image. All 30 seconds at f/2.8 with the 24mm Sigma lens, and Nikon D750 at ISO 6400. The frames were taken as part of a time-lapse sequence. <br />
<br />
Dynamic Contrast filter from ON1 applied to the ground, and Soft and Airy filter from Luminar applied to the sky for a soft Orton effect.
    Star Trails over Storm Mountain.jpg
  • Circumpolar star trails over a grand old barn in southern Alberta, on a fine spring night, May 23, 2018. Illumination is from the waxing gibbous Moon to the south. This is looking north to Polaris at top right. A thunderstorm is on the northern horizon with a lightning bolt as a bonus. <br />
<br />
This is a stack of 155 exposures taken over 2 hours, stacked using the Advanced Stacker Plus actions in Photoshop, and the Ultrastreaks effect. The ground is a mean-combined stack of the last 8 exposures, to smooth noise and preserve shadows that would otherwise be blurred in the stack of 155 frames due to the Moon’s motion.  <br />
<br />
All are 20-second exposures with the Laowa 15mm lens at f/2.8 and Sony a7III at ISO 800. A special effect filter was applied to the ground with Luminar to add the vintage toning.

  • The 1910 Liberty Schoolhouse, a classic pioneer one-room school, on the Alberta prairie under the stars on a spring night, with circumpolar star trails circling Polaris, and an aurora dancing to the north. Moonlight from the 8-day-old waxing Moon provides the illumination. <br />
<br />
This is a stack of 155 exposures for the sky for the star trails, and a mean-combined stack of 8 exposures for the ground to smooth noise, with a vintage effect using Luminar applied to the ground for the rustic tone. Star trail stacking with Advanced Stacker Plus Actions in Photoshop with Ultrastreaks effect. <br />
<br />
With the Laowa 15mm lens and Sony a7III camera. All 20 seconds at f/2.8 and at ISO 800, and taken as part of a 360-frame time-lapse.
    Liberty Schoolhouse with Star Trails.jpg
  • Circumpolar star trails and aurora over the Red Deer River, Alberta from the Orkney Viewpoint north of Drumheller on May 5, 2018.<br />
<br />
This is a stack of 650 images for the sky and river reflections using Advanced Stacker Plus actions in Ultrastreak mode. <br />
<br />
The ground comes from a stack of the final 8 images in the set, averaged to smooth noise. All exposures were 10 seconds at f/2 with the 14mm Sigma Art lens and Nikon D750 at ISO 3200. The frames were taken for a time-lapse movie of the aurora, which proved fairly quiet this night, so in stacking the sky, the aurora did not blur too much. Most of the curtain activity seen here was in the last dozen or so frames.

  • An urban star trail! It is possible! <br />
<br />
This is a stack of 275 2-second exposures to create the star trails of Orion, the Moon, and the stars of winter setting over the downtown core of Calgary on April 19, 2018. The sky was hazy, and of course there was city light pollution and moonlight, but the camera still picked up a good number of stars. <br />
<br />
The 275 exposures supply the sky and ground. A final image, taken 1 minute after the last star trail image, and blended with Lighten mode, adds the point-like stars at the end, to better define the constellations and make it clear these are stars. <br />
Orion is at centre; Sirius to the far left; and Venu setting to the far right. The crescent Moon is the bright streak. The Pleiades are above Venus. <br />
<br />
Taken from Tom Campbell Park with the location determined with The Photographer’s Emphemeris app to confirm Orion would be over the city core. <br />
<br />
The 275 frames were the first from 600 shot for a time-lapse, but in the later frames the stars of Orion set too low and get lost in the haze. <br />
<br />
During the shooting time, only one aircraft flew through, and I spot healed out its trail.<br />
<br />
All 2-second exposures with the 24mm Sigma lens at f/2.8 and Nikon D750 at ISO 400. Stacking the frames was with the Star Circle Academy Advanced Stacker Plus actions in Photoshop, with Ultrastreaks effect.
    Orion Star Trails over Calgary.jpg
  • Orion rising in star trails and in the moonlight, at Dinosaur Provincial Park, Alberta, on November 27, 2017. Light is from the 8-day waxing Moon off camera to the right. <br />
<br />
This is a stack of 100 exposures for the star trails, followed by a gap of a miniute, then a final single exposure to add the point-like stars at the ends of the trails. Another gaussian blur layer adds the star glows. The 100 star trail frames were extracted from the end of a 1200-frame time-lapse sequence. <br />
<br />
All exposures were 10 seconds at f/2 with a 24mm Sigma Art lens and Nikon D750 at ISO 800. Stacking was with the Advanced Stacker Plus actions from Star Circle Academy, v14e.

  • A circumpolar star trail composite with Northern Lights, on October 13, 2017, shot from home in southern Alberta.<br />
<br />
The Big Dipper is at bottom centre; Polaris is at top centre at the axis of the rotation. The bottom edge of the curtains are rimmed with a pink fringe from nitrogen.<br />
<br />
This is a stack of 200 frames taken mostly when the aurora was a quiescent arc across the north before the substorm hit. An additional single exposure is layered in taken about 1 minute after the main star trail set to add the final end point stars after a gap in the trails. So the aurora is a blend of 201 images. The ground is a mean averaged stack of 5 exposures to smooth noise. <br />
<br />
Stacking was with the Advanced Stacker Plus actions using the Ultrastreaks mode to add the direction of motion from the tapering trails. <br />
<br />
All are part of a 1000-frame time-lapse. Each frame is 3 seconds at f/2 and ISO 6400 wth the Sigma 14mm lens and Nikon D750.

  • Orion (right) and Sirius (upper right) setting into the west over Loch Ard Gorge on the Great Ocean Road, Victoria, Australia, with illumination from the rising Moon a day past full behind the camera to the east. <br />
<br />
This is the location of the wreck of the Loch Ard immigrant ship, where only two survived by swimming ashore at this gorge and climbing the cliffs to find a ranch house nearby.<br />
<br />
This is a stack of 100 exposures for the sky and water, each 15 seconds, with the ground coming from one frame in the sequence to prevent the moving shadows from the rising Moon from blurring detail. <br />
<br />
All with the 14mm Rokinon lens at f/2.5 and Canon 6D at ISO 800. Stacked with Advanced Stacker Action Elastic Stars effect.
    Orion Star Trails At Loch Ard Gorge.jpg
  • Star trails over Moraine Lake from Aug 31, 2016. This is a stack of about 300 exposures for the sky and 8 for the ground to smooth noise. Each exposure was 15 seconds at f/2 with the Sigma 20mm lens. Master dark frame applied in processing. <br />
<br />
Stacking with Advanced Stacker Plus actions in Photoshop.

  • A composite of images stacked to create star trails descending over Lake Louise and Victoria Glacier in Banff National Park, Alberta, August 29, 2016. The Milky Way forms the bright band and the bright star at top is Altair. <br />
<br />
The sky comes from about 100 frames stacked with a Lighten mode blend to create the star trails, while the ground comes from a stack of 8 images averaged to smooth noise. A msater dark frame was applied to reduce discoloration. Each exposure was 10 seconds at f/1.6 with the Sigma 20mm lens and Nikon D750 at ISO 6400. The frames were shot as part of a 300-frame time-lapse sequence.
    Star Trails over Lake Louise.jpg
  • Circumpolar star trails over the old pioneer Larson Ranch in the Frenchman River Valley, in Grasslands National Park. Saskatchewan. Polaris is at upper left. This is facing east to the rising sky.<br />
<br />
This is a stack of 90 images for the sky, to create the star trails, and a stack of 5 exposures taken at the beginning of the sequence for the ground, to smooth noise. Each exposure was 45 seconds at f/2.8 with the 15mm full-ftame fish-eye lens and Canon 5D MkII at ISO 5000.
    Star Trails over Larson Ranch.jpg
  • The stars trailing in motion over the sandstone formations of Writing-on-Stone Provincial Park in southern Alberta, on July 31, 2016. The foreground is illuminated only by natural starlight and sky glow; no artificial illumination employed to “light paint” the foreground. This was at New Moon, so there was no moonlight. <br />
<br />
While this is a highly-manipulated image, it is a composite of exposures all taken at the same shoot with the same fixed camera. The ground did not come from some other night or shooting session. <br />
<br />
This is a stack of 100 images, all 30-second exposures at f/2 and ISO 4000, to create the star trails, with the last image blurred to out a glow around the stars at the end point of the trails and to being out the Milky Way. The ground is from a single 6.5-minute exposure taken at the end of the sequence at f/4 and ISO 1600 for more depth of field, less noise, and more detail in the foreground. Star trail stacking with Advanced Stacker Plus actions using Comet effect. Compositing in Photoshop. Other layers not seen here are included in the master image to compare the difference in the foreground, between a single short exposure, a single long exposure at lower ISO, and a stack of 8 exposures averaged, to compare noise and detail in demos. A single sky layer is also included. An LENR dark frame was applied to the 6.5-minute foreground image.

    Star Trails over Rustic House.jpg
  • Circumpolar star trails over the historic but sadly neglected St. Anthony’s Church between Bow Island and Etzikom, Alberta. The Big Dipper is at left, Polaris at top. The Roman Catholic church was built in 1911 by English, Russian German immigrants. It served a dwindling congregation until 1991 when it closed. At that time workers found a time capsule from 1915 with names of the priest and parisioners of the day. In summer of 2014 the Church suffered its latest indignity when the iron cross on its steeple tower was stolen. It was there when I stopped at this Church on a site scouting trip in May 2014. I planned to return on a moonlit night and did on July 29, 2015. A nearby house had been torn down and the cross was now gone. <br />
<br />
This is a stack of 300 6-second exposures with the Canon 6D at ISO 1600 and 16-35mm lens at f/2.8. Bright light from a 13-day Moon lights the scene, making for very short exposures. The ground comes from one exposure to keep shadows sharp. The final stars also come from another single exppsure taken two minutes after the last trail image. I used the Advanced Stacker Actions to stack the trails.
    Star Trails over St Anthonys Church.jpg
  • Summer solstice twilight and circumpolar star trails over the badlands of Dinosaur Provincial Park, Alberta. Some bright noctilucent clouds are visible low on the northern horizon. I shot this June 15, 2015 as part of a shoot for a “star trail” video tutorial, as an example image.<br />
<br />
This is a stack of the first 200 frames of 275 shot for a time-lapse, each 15 seconds at f/2.8 with the Rokinon 14mm lens and Canon 6D at ISO 1600. I stacked them in Advanced Stacker Actions with the ultrastreak mode. The foreground comes from a mean blend of the first 8 frames, to smooth noise, and to provide a brighter foreground from early in the sequence when the sky and ground were brighter.
    Solstice Star Trails at Dinosaur Par...jpg
  • A star trail scene in the summer twilight, taken June 7, 2015 from southern Alberta, over an old farm house near home. The brightest trail at right is from Venus, to the left of it is Jupiter. Various satellites, including the International Space Station, provide the other dashed streaks. The twilight of near summer solstice provides the deep blue sky. <br />
<br />
This is a stack of 300 frames taken for a time-lapse sequence but stacked here into a single image using the Advanced Stacker Actions Photoshop plug-ins. The ground is from one frame from the beginning of the sequence when the sky and ground were brighter. Most frames were 6 seconds at f/2.8 and ISO 800 with the Nikon D750 and Sigma 24mm lens.
    Star Trails over Old House.jpg
  • The old Liberty Schoolhouse at Majorville, Alberta, with some fun with lighting the interior. This schoolhouse was built in 1909, as the classic one room school on the prairies.

  • Circumpolar star trails over the upper field of the Texas Star Party, May 13, 2015. The star party attracts hundreds of avid stargazers to the Prude Ranch near Fort Davis, Texas each year to enjoy the dark skies. The three observing fields are filled with telescopes from the basic to sophisticated rigs for astrophotography. I aimed the camera to look north over the field to capture the stars circling around Polaris in circumpolar trails over about 1 hour. Some cloud and haze obscured parts of the sky. Lights from cities to the north add the sky glow at right. The streaks at top are from the stars of the Big Dipper.<br />
<br />
This is a stack of 55 exposures, each 1 minute long, at f/2.8 with the 14mm lens and Canon 5D MkII at ISO 3200. The foreground comes from a single image in the series, masked and layered in Photoshop. The images were stacked using the Long Trails tapering effect with the Advanced Stacker Actions from Star Circle Academy.

  • Circumpolar star trails spinning behind Double Arch at Arches National Park, Utah, as the waning gibbous Moon lights the arches toward the end of the sequence. The Big Dipper is streakng into frame at top right from behind the butte at right, while Jupiter is the bright object at top left streaking down into the scene. <br />
<br />
During the shoot, other photographers were lighting the Arches but this did not affect my shoot, as my foreground came from near the end of the shoot after they had all left and I had natural illumination to light the Arches.<br />
<br />
This is a stack of 160 frames taken over 2.5 hours from 9:30 to midnight, starting in moonless darkness, then brightening as the Moon rose in the last hour of the shooting, lighting the sky and arches. The nearest arch casts its shadow onto the distant arch, with its shadow shape matching the other arch.<br />
<br />
The frames were stacked with Star Circle Academy’s “Advanced Stacker Actions” for Photoshop using the Long Streaks effect. The foreground comes from a stack of 8 frames for noise reduction, taken toward the end of the shooting with the moonlight illumination. An additional frame taken a couple of minutes after the last star trail frame adds the short unstreaked stars at the head of the trails. <br />
<br />
Each exposure was 45 seconds at f/2.8 and ISO 3200 with the Canon 6D and 14mm Rokinon lens. Dark frames taken at the end of the night (8 stacked in Mean combine for a master dark) were also subtracted from each of the foreground and star trail stacks, which reduced noise speckling.

  • Orion and the stars of the winter sky trailing as they set behind and through Turret Arch, in Arches National Park, Utah. I shot this April 6, 2015 after twilight but before the waning Moon rose, so the sky was dark. Illumination is from stars and the sky – no artificial light provided, and the Moon was not up.<br />
<br />
This is a stack of 4 x 8-minute exposures at ISO 250 for the ground and long star trails, plus an initial short 30-second exposure at ISO 4000 for the star points at the start of the trail, all with the Rokinon 14mm lens at f/2.8 and Canon 6D.
    Orion Star Trails Thru Turret Arch.jpg
  • Circumpolar star trails over the moonlit Mimbres Valley near Lake Roberts in the Gila National Forest, in southern New Mexico. Illumination is from the waxing gibbous Moon. Polaris is at upper left, while the stars of the Big Dipper are rising at right, with just the Bowl’s Pointer stars visible at the start of the sequence, then rising to bring the entire Dipper above the horizon, with Alkaid, the end star of the handle, just clearing the ridge at right. (I had to wait till 10 pm for the star to appear so the entire Dipper would be in the final frames.)<br />
<br />
The sequence was shot over 3 hours. <br />
<br />
This is a stack of 340 frames, each 32 seconds at f/2.8 and ISO 800 with the 24mm lens and Canon 6D. The ground comes from a final 2 minute exposure at f/8 for greater depth of field in the foreground. Stacked with Star Circle Academy’s Advanced Stacker Actions using the Elastic Stars effect. I used LRTimelapse to also vary the color balance over the sequence as the illumination shifted and clouds changed the sky colour. This will be more noticeable when the frames are exported into a time-lapse movie.

  • The constellations of Orion and Canis Major in star trails over the Gila National Forest, New Mexico. Taken January 27, 2015 under the light of waxing quarter Moon off frame at upper right. <br />
<br />
This is a stack of two exposures: a short 25-second exposure at f/4 and ISO 3200 for the point-like stars at the start of the trails, followed after a gap in time by a single 10-minute exposure at f/9 and ISO 400, for the long trails, with the small f/9 aperture providing greater depth of field for foreground sharpness. The ground comes from the longer exposure. All with the 24mm lens and Canon 6D.
    Orion Star Trails over the Gila.jpg
  • Circumpolar star trails on a moonlit night in the Gila National Forest in southern New Mexico, north of Pinos Altos. Polaris is at upper left, the Little Dipper hanging below it, and the stars of the Big Dipper are rising at right, with the end star of the handle still to clear the horizon. Illumination is from the waxing quarter Moon. The night had a lot of high cloud drifting through, adding the streaks and patchiness to the sky. <br />
<br />
This is a stack of 80 exposures, each 45 seconds with the 24mm lens at f/4 and Canon 6D at ISO 1600. The foreground comes from a single frame, the first, to minimize blurring and contrast loss from using a foreground blended from 80 shots taken over an hour while the Moon and shadows moved. The last frame was enhanced with larger star glows to punch up the appearance of the end stars and pattern of the Dipper. Stacking was performed with the Star Circle Academy’s Advanced Stacker Actions, using the Long Streaks effect.

  • Star trails over Patricia Lake and Pyramid Mountain in Jasper National Park. Moonlight provides the illumination and a faint aurora is at lower right in the northeast. The Big Dipper is the main pattern right of centre. <br />
<br />
This is a stack of about 100 frames to create the star trails using Advanced Stacker Plus actions in Photoshop with the Long Comet streaks effect. Two additional single frames are layered in, one for the ground from one of the frames and another for the sky to create the point-like stars after a gap at the ends of the trails. This frame came from a minute or so after the last trail frame was taken. Each exposure was 20 seconds at ISO 1600 with the Canon 60Da and Rokinon 14mm lens at f/2.8. The frames had to be cropped to cut out car lights from a road off frame at right.
    Patricia Lake Star Trails.jpg
