  • A widefield view of Orion's Belt and Sword showing the complex of nebulosity in the area. The three Belt stars are at top (L to R): Alnitak, Alnilam and Mintaka, with the dark Horsehead Nebula (B33) below Alnitak. Above Alnitak is the pinkish Flame Nebula, NGC 2024. At bottom are Messiers 42 and 43, making up the Orion Nebula, with the bluish Running Man Nebula above it, aka NGC 1973-5-7. Above it is the star cluster NGC 1981. Messier 78 is just on frame at upper left. Numerous other bits of emission and reflection nebulas populate the field amid a backdrop of faint emission nebulosity. The stars around the Belt belong to the large star cluster Collinder 70.  This is a blend of two stacks of images: 15 x 8 minutes through an IDAS NBX dual narrowband filter to bring out the faint nebulosity, and 15 x 4-minutes with no filter for the more natural star colours and colours of the Orion, Flame and Horsehead (IC 434) Nebulas. So a total of 3 hours of exposure time. I did not take shorter exposures for the Orion Nebula core.   All were with the William Optics RedCat 51mm astrograph at f/4.9 and filter-modified (by AstroGear) Canon EOS R at ISO 3200 for the filtered shots and ISO 800 for the unfiltered shots. Taken from home January 22, 2023 on a rare clear winter night. Autoguided and dithered with the Lacerta MGEN3 autoguider. No darks or LENR employed.   All stacking, alignment and masking in Photoshop. Luminosity masks with Lumenzia helped bring out the nebulosity, as did a mild application of the Nebula FIlter action in the PhotoKemi StarTools Actions set. Noise reduction with RC-Astro Noise XTerminator. The filtered set has had all the stars removed using RC-Astro Star XTerminator, so it contributed just the nebulosity, Stars come from the unfiltered set for tighter stars with more natural colours.

  • 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. <br />
<br />
Taken from home in Alberta, December 3, 2022, with the old rake as a foreground object.<br />
<br />
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.

  • A portrait of the constellation of Orion taken in monochrome in the deep red light of the hydrogen-alpha wavelength using a narrowband filter, to emphasize the vast clouds of interstellar gas within and around Orion. <br />
<br />
The Orion Nebula is the bright object at lower centre; the Horsehead Nebula below the Belt of Orion is near centre; the bright object at upper left is the Rosette Nebula in Monoceros. The large circular glow at top around the head of Orion is Sharpless 2-264, the Lambda Orionis nebula. The curving arc on our left side of Orion is Sharpless 2-276, aka Barnard's Loop. <br />
<br />
This is a stack of 24 x 4-minute exposures with the red-sensitive Canon Ra camera at ISO 1600 shooting through the Canon RF28-70mm lens at 50mm and wide open at f/2. The filter was the Astronomik 12nm Ha clip-in filter. This was taken Feb 10, 2022 in bright moonlight with the waxing gibbous Moon just off frame at top, creating some challenging gradients.
    Orion in Ha (RF28-70mm at 50mm).jpg
  • This is a portrait of the main nebulosity in Orion in his Sword, including: the Orion Nebula itself (at centre), aka Messiers 42 and 43, and the Running Man Nebula above (aka NGC 1973-5-7). The bright blue star cluster NGC 1981 shines above the Running Man. The subtle reflection nebula NGC 1999 is below M42 but a bit lost amid the other faint and dusty nebulosity. <br />
<br />
The field of view is 4° by 2.7°.<br />
<br />
This is a stack of 11 x 6-minute exposures with an Askar FRA500 astrograph (500mm focal length at f/5.5), and stock Canon R6 camera at ISO 800. The camera was not modified and no filters were employed here. I did not take short exposures for the core of the bright Orion Nebula. Some light haze added star glows. <br />
<br />
Nebulosity is brought out in Photoshop using successive curves with luminosity masks generated by Lumenzia, and with applications of the Nebula Filter action from the PhotoKemi StarTools action set, and Enhance DSO from the Astronomy Tools action set. All alignment and layering was in Photoshop. Taken from home January 26, 2022. Autoguided and dithered with the MGEN3 guider, with LENR dark frame subtraction also applied to each frame in camera to eliminate the edge amp glow the R6 exhibits. It was about -5° C this night.
    Orion Nebula (FRA500 R6).jpg
  • This is a portrait of the main nebulosity in Orion around the Belt and Sword, including: the Orion Nebula itself (at bottom), aka Messiers 42 and 43; the Running Man Nebula above (aka NGC 1973-5-7); the dark Horsehead Nebula (B33) silhouetted in front of the bright nebula IC 434; the Flame Nebula (NGC 2024) above Alnitak; and at top left the reflection nebulas Messier 78 and NGC 2071. <br />
<br />
However, the entire field is filled with streamers and patches of emission and reflection nebulas. The three stars of the Belt of Orion are at centre, from L to R: Alnitak, Alnilam, and Mintaka. The large loose open star cluster Collinder 70 surrounds the centre star of the belt, Alnilam. The bright blue star cluster NGC 1981 shines above the Running Man. <br />
<br />
The field of view is almost 9° by 6°.<br />
<br />
This is a stack of just 11 x 4-minute exposures with an Askar FMA230 astrograph (230mm focal length at f/4.5), and stock Canon R6 camera at ISO 800. The camera was not modified and no filters were employed here. The field could have used more exposures but clouds and altitude prevented that! Some light haze on some frames added star glows. I did not take short exposures for the core of the bright Orion Nebula. <br />
<br />
Nebulosity is brought out in Photoshop using successive curves with luminosity masks generated by Lumenzia, and with applications of the Nebula Filter action from the PhotoKemi StarTools action set, and Enhance DSO from the Astronomy Tools action set. All alignment and layering was in Photoshop. Taken from home January 25, 2022. Autoguided and dithered with the MGEN3 guider, with LENR dark frame subtraction also applied to each frame in camera to eliminate the edge amp glow the R6 exhibits. It was about -5° C this night.
    Orion Nebulas (Askar230 R6).jpg
  • The partial eclipse of the Moon of November 19, 2021, with the Moon below the Pleiades star cluster, M45, and near the Hyades cluster and Aldebaran at right, all in Taurus, the hallmark setting of this eclipse, which at maximum (about 20 minutes before this sequence was taken at 2:22 am MST) was 97% partial, so not quite total. Orion is at left. A large portion of the Moon was outside the umbra and bright when this sequence was shot. <br />
<br />
The long exposures inevitably add the glow around the Moon, from the bright portion of its disk still in full sunlight and from some light haze in the sky, which added the sky gradients and star glows. But this is an authentic scene, not a Moon pasted onto a sky background taken on another night to simulate the scene. <br />
<br />
Taken from a site near Rowley, Alberta after a chase north to get out from under clouds and haze into clearer skies to allow exposures like this to record the starfield. <br />
<br />
This is a stack of 2 x 30-second exposures at ISO 1600 for the base sky, blended with 15s, 5s, 1.6s, and 0.5s exposures at ISO 800, all with the Canon EOS R6 camera and Canon RF28-70mm lens at 33mm and f/2.8 and on the Sky-Watcher Star Adventurer Mini tracker.<br />
<br />
Images blended with luminosity masks created with ADP Panel Pro/LumiFlow, but with manual manipulation to smooth the blend.
    Eclipsed Moon Near Orion - Nov 19, 2...jpg
  • The full array of northern winter stars and constellations, including Orion, setting in the evening twilight at Dinosaur Provincial Park, Alberta, on April 20, 2021, so about the last opportunity to shoot the scene for the season. <br />
<br />
Light from the waxing quarter Moon just off frame at top illuminates the scene, plus the sky is still bright with twilight colours in the west. <br />
<br />
Orion is just all visible but with Rigel about to set. The Hyades and Pleiades in Taurus are just over the formation at right. Sirius in Canis Major is over the formation at left. Procyon in Canis Minor is at left of centre. Castor and Pollux in Gemini are the two stars at top. Capella in Auriga is at upper right. Perseus is at far right. Mars is dim at centre frame as an "extra star" between Gemini and Auriga. <br />
<br />
This is a stack of 4 x 30-second tracked exposures for the sky at ISO 800 and 4 x 1-minute untracked exposures for the ground at ISO 200, at f/4 with the 14mm Samyang SP lens on the Canon EOS Ra camera. The tracker was the Star Adventurer 2i. This is not a multi-segment panorama but is a multi-exposure stack. Stacked, masked and blended in Photoshop.

  • Orion, Sirius and the winter stars over my home in southern Alberta, with a bright waxing Moon in Taurus. Taken February 19, 2021.
    Winter Sky over Home v1 (Feb 19, 202...jpg
  • This is composition taking in many of the bright and not so bright nebulas in and around the Sword and Belt of Orion. <br />
<br />
At bottom is the bright Orion Nebula, Messier 42. Above it is the bluish Running Man Nebula, NGC 1973-5-7. At centre is the famous dark Horsehead Nebula, B33, silhouetted against the bright glow of IC 434. Above it, and above the blue star Alnitak is the pinkish Flame Nebula, NGC 2024. At top left is the reflection nebula complex of Messier 78 and NGC 2071. Numerous other small patches of nebulosity shine around the Belt stars at right of centre. The large Barnard's Loop, Sh-2-276, just sneaks into the corner of the frame at top left. <br />
<br />
This is a blend of filtered and unfiltered images: a stack of 8 x 8-minute exposures through an Optolong L-Enhance filter blended with a stack of 12 x 8-minute exposures without a filter, with the filtered shots at ISO 3200 and unfiltered shots at ISO 800. Stacks of 4 x 2-minute at ISO 800 and 4 x 2-minute at ISO 200 are also blended in with luminosity masks to retain the details in the bright core of the Orion Nebula, and to shrink the stars. <br />
<br />
All were with the Canon EOS Ra mirrorless camera shooting through the William Optics RedCat 51mm astrograph at f/5 (250mm focal length). The unfiltered shots were taken the night after the filtered shots, as incoming haze and ice fog cut short the shoot on the first night, January 9, 2021, and prevented more filtered shots (for lower noise) without haze. As it is, some haze surrounds the stars. The RedCat is equipped with the Starizona filter drawer accessory to make it easier to swap the filter in and out without affecting camera position. <br />
<br />
This was on the Astro-Physics Mach1 mount and guided with the made-in-Hungary Lacerta MGEN3 autoguider which also controlled the camera and applied a dithering motion between each shot to help remove thermal noise. No dark frames were taken nor was Long Exposure Noise Reduction applied in camera, though it was -5° C these nights, chill
    Nebulas in Orion (RedCat EOS Ra).jpg
  • This is a portrait of the winter sky rising in the southeast on January 9, 2021, taken from home in Alberta. <br />
<br />
The constellation of Orion is at centre with blue-white Sirius in Canis Major below and reddish-yellow Aldebaran in Taurus above. Castor and Pollux in Gemini are at left. Procyon in Canis Minor is between the Castor-Pollux pair and Sirius. Bright star clusters flank the scene, with the Pleiades (M45) at top and the Beehive Cluster (M44) in Cancer at far left. Several other smaller star clusters in and along the Milky Way are also visible, even at this scale with an ultra-wide lens.<br />
<br />
This is a stack of 10 30-second tracked exposures with the 15mm Venus Optics Laowa lens at f/4 on the Sony a7III at ISO 6400. and taken as part of lens testing this night.
    Winter Sky Rising (January 2021).jpg
  • An image with some unusual colour contrasts for a deep-sky image — with blue Bellatrix, a green comet, and the huge red Lambda Orionis nebula.<br />
<br />
This is Comet ATLAS (C/2020 M3) seen here as the green glow above the bright blue star Bellatrix in the shoulder of Orion, and approaching the large diffuse red nebula surrounding the “head” star of Orion, Lambda Orionis. aka Meissa. The large nebula complex is catalogued as Sharpless 2-264. At right, above the comet, is the smaller emission and reflection nebula catalogued as vdB (vandenBurgh) 38. The sparse star cluster  surrounding Lambda Orionis is Collinder 69.<br />
<br />
This was the night of November 15/16, 2020, with the comet moving rapidly northward a day after its closest approach to Earth and three weeks after its perihelion, or closest approch to the Sun. On the next nights the comet would have been within the nebula. <br />
<br />
This is a stack of 8 x 8 minute exposures without a filter, blended with 6 x 15-minute exposures through an Optolong L-Enhance narrowband nebula filter, to bring out the faint nebulosity. <br />
<br />
The comet image itself is from just one of the filtered frames layered and masked to reveal just the comet. But even in the single 15-minute exposure its image trailed slightly as its motion was quite rapid. I used a filtered shot for the comet as its green/cyan glow did pop out more than in the unfiltered shots, though the more usual cyan colour of a comet has been altered a little by the narrowband filter and its bandpass of the green OIII lines. <br />
<br />
All were with the William Optics RedCat 51mm astrograph at f/4.9 and with the Canon EOS Ra, with the filtered shots at ISO 3200 and unfiltered shots at ISO 800. Images were autoguided, with dithering, using the Lacerta MGEN3 stand-alone autoguider. I also used its polar alignment routing this night to refine the mount’s polar alignment and it seemed to work! <br />
<br />
All images stacked, aligned and blended with Photoshop.
    Comet ATLAS (C2020 M3) in Orion.jpg
  • This is a 360° panorama of the dawn sky on September 21, 2020 from home in Alberta, with the Zodiacal Light in the east at left, with bright Venus embedded in the Zodiacal Light. <br />
<br />
Mars, near opposition, is bright and orange at right of centre. The two planets nicely flank the Milky Way and the bright stars of Orion and the winter sky. <br />
<br />
The summer Milky Way is setting at far right in the northwest. The Big Dipper is at far left to the northeast. The Beehive Cluster, M44, is above Venus; the Pleiades, M45, is at top; while the Andromeda Galaxy, M31, is at upper right. Sirius is above the horizon to the south at left of centre. The stars of Leo are just rising amid the twilight below Venus.<br />
<br />
This is a panorama of 12 segments, at 30° spacing, with the Sigma 14mm Art lens at f/2 (in landscape orientation) and Nikon D750 at ISO 1600, all 30 seconds untracked. Stitched with PTGui. Camera Raw handled it but give no control over the framing. The light pollution from Strathmore and Calgary light the horizon at right. <br />
<br />
I shot this about 5:30 am just as the sky was brightening with twilight, enough to colour the sky but not wash out the Milky Way and Zodiacal Light, a narrow window of time as the sky changes colour and brightness surprisingly quickly, even at my latitude of 51° N. This was shot on a very clear morning after several days of smoky skies from fires in the western U.S.
    Dawn Sky Panorama (Sept 21, 2020).jpg
  • 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/<br />
<br />
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.

  • The stars of the northern winter sky rising at dawn on the morning of August 14, 2020, from home in southern Alberta. <br />
<br />
The waning crescent Moon is overexposed here, shining above bright Venus , then in southern Gemini as a bright “morning star” in the east. Mars is also bright and reddish, to the south at far right. Orion is rising over the ripening wheatfield at centre. Above Orion is Taurus with the Hyades and Pleiades star clusters. The bright star to the left and above the Moon is Capella in Auriga. Castor and Pollux are rising at left. A flaring satellite trail appears below Venus. <br />
<br />
This is a two-segment panorama with the 14mm Sigma Art lens at f/2.5 and Nikon D750 at ISO 800 for 20 seconds each. Stitched with PTGui which erases all the metadata from the image. I added a mild Orton Glow effect with Luminar Flex.

  • The stars of the northern winter sky rising at dawn on the morning of August 14, 2020, from home in southern Alberta. <br />
<br />
The waning crescent Moon is overexposed here, shining above bright Venus , then in southern Gemini as a bright “morning star” in the east. Mars is also bright and reddish, to the south at upper right. Orion is rising over the ripening wheatfield at centre. Above Orion is Taurus with the Hyades and Pleiades star clusters. The bright star to the left and above the Moon is Capella in Auriga. Castor and Pollux are rising at far left.<br />
<br />
This is a stack of 4 images for the ground to smooth noise and 1 image for the sky, all with the 14mm Sigma Art lens at f/2.5 and Nikon D750 at ISO 800 for 25 seconds each. I added a mild Orton Glow effect with Luminar Flex.
    Winter Sky at Dawn (August 14, 2020).jpg
  • This is a panorama of the evening sky on March 25, 2020, with brilliant Venus high in the west at centre just after the date (March 24) of its greatest elongation in the evening sky for 2020. It appears here about as high as it can get with the ecliptic tipped up to a high angle in spring. To the left is Orion and the winter stars in the twilight, including Sirius at far left.  Just above the horizon right of centre in the bright twilight is the day-old thin crescent Moon about to set. Above Venus are the Pleiades and Hyades star clusters. <br />
<br />
This is a panorama of 5 segments with the Nikon D750 and 24mm Sigma lens, stitched with PTGui.  Each segment was 8 seconds at ISO 400 and f/2.8.

  • This is the evening sky on March 25, 2020, with brilliant Venus high in the west just after the date (March 24) of its greatest elongation in the evening sky for 2020. It appears here about as high as it can get with the ecliptic tipped up to a high angle in spring. To the left is Orion and the winter stars in the twilight. Just above the horizon at bottom right in the bright twilight is the day-old thin crescent Moon about to set. Above Venus are the Pleiades and Hyades star clusters. <br />
<br />
This is a single exposure with the Nikon D750 and 24mm Sigma lens, at 8 seconds at ISO 400 and f/2.8.
    Orion and Venus at Dusk (March 25, 2...jpg
  • A portrait of Orion and the northern winter Milky Way, on a February night, 2020. The Orion Nebula is the bright, overexposed pink glow below the Belt of Orion, while the curving arc of red is Barnard’s Loop, now thought to be a supernova remnant. The bright red glow at upper left is the Rosette Nebula.  Red Betelgeuse was at its minimum then, at about the same brightness as Bellatrix to the right — Betelgeuse is usually about as bright as blue-white Rigel at lower right. However, Betelguese began to re-brighten in the nights after this. <br />
<br />
This is a stack of 8 x 2-minute exposures at ISO 800 with no filter and 6 x 3-minute exposures at ISO 1250 with a NISI Natural Night light pollution filter, all with the Sigma 50mm lens at f/3.2 and red-sensitive Canon EOS Ra camera on the iOptron SkyGuider Pro tracker. An additional exposure without the NISI but through a Kenko Softon A diffusion filter adds the star glows.  Taken from home in Alberta on February 24, 2020.
    The Constellation of Orion (EOS Ra 5...jpg
  • The constellation of Orion photographed in deep red Hydrogen-Alpha light and rendered in monochrome. The filtered view brings out the very faint nebulosity in and around Orion, most invisible to the eye.   The Belt of Orion is just below centre, with the region of the Horsehead Nebula below the left star of the Belt, Alnitak. Below it is the very bright Orion Nebula. Surrounding the left side of Orion is the arc of Barnard’s Loop, now thought to be a supernova remnant.   The large circular nebula around Orion’s head is the Lambda Orionis Nebula or Sharpless 2-264. At left in Monoceros is the bright Rosette Nebula, NGC 2237, and above it the fainter nebulosity Sharpless 2-273 around the Cone Nebula. The small patch at top is Lower’s Nebula, Sharpless 2-261.  Betelgeuse, at a record dim magnitude visually at this time, here looks more normal in brightness, at least brighter than Bellatrix at right, as seen here in red light, as Betelgeuse is a red giant star.   I shot this using an Astronomik 12nm clip-in H-alpha filter on the Canon EOS Ra camera, a factory-modified red-sensitive mirrorless camera designed to pick up more of this deep red H-a nebulosity than can a normal camera. As the original image is simply deep red, it is best rendered as a monochrome image. However, this could be combined with colour images to make an enhanced full-colour image.  This is a stack of 9 x 8-minute exposures at f/2.2 with the Sigma 50mm lens and Canon EOS Ra at ISO 1600, on the iOptron Sky Guider Pro tracker. Taken before moonrise on February 12, 2020. Stacked, registered and blended with Photoshop 2020. Nik Silver EFX selenium and Luminar Flex Soft Glow filters added for artistic effect, to add a soft blue glow to the image, not red.   The temperature was about -15° C this night with a fine chill wind!
    Orion in H-Alpha Light (50mm).jpg
  • Orion and the winter stars and Milky Way in a wide-angle scene sweeping up from the horizon to past the zenith. Sirius and Canis Major are at bottom left while Cassiopeia and Perseus are at upper right. Orion is below centre. At centre are the Taurus Dark Clouds and the constellations of Taurus and Auriga. Gemini is at left. The Winter Hexagon stars are all framed in this scene, and more! The glow of Zodiacal Light is at right. Betelgeuse was then at a record minimum brightness. <br />
<br />
This is a stack of 8 x 4-minute tracked exposures with the Canon 15mm full-frame fish-eye lens at f/2.8 and stock Canon 6D MkII camera at ISO 800, on the iOptron SkyGuider Pro tracker. Thus the blurry ground. Taken from home at latitude 51° N. on a perfect winter night, January 25, 2020.
    Orion and Winter Milky Way from Home...jpg
  • The constellation of Orion with red Betelgeuse then at a record dim magnitude looking similar in brightness to magnitude 1.6 Bellatrix at right, and much fainter than Rigel at lower right, which it usually rivals in brightness.  <br />
<br />
This is a stack of 4 x 4-minute tracked exposures through the NISI Natural Night filtter with the Sigma 50mm lens at f/2.8 and stock (not modifed) Canon 6D MkII camera at ISO 800. A fifth exposure taken though the Kenko Softon filter adds the star glows. Taken from home in Alberta with the iOptron SkyGuider Pro tracker.
    Orion with Dim Betelgeuse (Jan 25, 2...jpg
  • Orion on January 2, 2020 in the moonlight from a first quarter Moon, with orange Betelgeuse much dimmer than usual, a little brighter than Bellatrix at right.<br />
<br />
This is a single 4-minute exposure with the 50mm Sigma lens at f/2.8 and Canon EOS Ra at ISO 400 and through the NISI Natural Night filter, and on the iOptron SkyGuider Pro tracker. Haze moving in added the natural star glows (no filter was needed to add those) and the haze ruined subsequent images in the set. So this is from only one exposure but serves to record the brightness of Betelgeuse this night. Gradient Xterminator filter used to even out the sky illumination.
    Orion (50mm EOS Ra).jpg
  • Orion and Taurus (at top) beside the Milky Way, with Betelgeuse dimmer than usual at this time (about magnitude +1.3) during one of its fading episodes. The Taurus Dark Clouds are at top. Barnard’s Loop, apparently now thought to be a supernova remnant and not a bubble, is at lower left encircling Orion. The Rosette Nebula is at far left. The Auriga clusters and nebulas are at top, as is M35 in Gemini. <br />
<br />
This is a stack of 8 x 3-minute exposures with the 35mm Canon lens at f/2.8 and Canon EOS Ra at ISO 800. 4 shots were through the NISI Natural Night light pollution reduction filter and 4 were through the Hoya Red Enhancer filter, taken as part of testing. An additional exposure through the Kenko Softon filter adds the star glows. Taken from home on a very clear night, December 29, 2019 on the iOptron SkyGuider Pro. The red nebulas showed up better here than in a similar shot taken the night before due to the clearer sky and use of the filters. Even so, I had to remove a lot of sky gradients at the bottom (as that area of sky is low for me), so this image serves as a good demo of that process.
    Orion and Taurus with Filters (35mm ...jpg
  • Orion and and Sirius in Canis Major low on my southern horizon from home in Alberta at latitude 51° N.  Betelgeuse is dimmer here than usual as this was December 28, 2019 and the star was in a major downtown in brightness. The star cluster M41 is below Sirius. The stars of Lepus are below Orion. <br />
<br />
This is a stack of 6 x 1.5-minute exposures at f/2.8 with the Canon 35mm lens and Canon EOS Ra at ISO 1600, on the iOptron SkyGuider Pro, plus an additional exposure through the Kenko Softon A filter layered in for the enhanced star glows. However, thin haze and ice crystals added natural star glows. Plus haze and airglow added the bands of colour.
    Orion and Sirius (35mm EOS Ra).jpg
  • Orion rising on December 28, 2019 with yellow-red Betelgeuse at centre dimmer than usual as it drops by nearly a magnitude from its normal brightness, during one of its occasional dim episodes as a long-period variable star. It is a red supergiant that varies between 0.0 and +1.3 magnitude.  Here it definitely looks dimmer than yellow Aldebaran at top in Taurus, and blue-white Rigel at bottom in Orion. Betelgeuse loolks similar in brightness to blue Bellatrix to the right of Betelgeuse, with both stars forming the shoulders of Orion. <br />
<br />
This is a stack of 4 x 1-minute tracked exposures plus a single exposure through the Kenko Softon A filter to add the star glows. All on the iOptron Sky Guider Pro and with the Canon EOS Ra and 35mm lens at f/2.5.  Taken from home in Alberta.
    Orion Rising with Dim Betelgeuse (De...jpg
  • Orion rising on December 21, 2019 with yellow-red Betelgeuse at upper centre reportedly dimmer than usual as it drops to one of its occasional dim episodes as a long-period variable star. It is a red supergiant that varies between 0.0 and +1.3 magnitude. <br />

  • The Canadian Pacific Holiday Train at its last stop for its 2019 tour, in Gleichen, Alberta, near the Siksika Nation and near home, on December 18, 2019. At each stop, performers present a concert from the stage car to the trackside audience, and raise funds for charity. On this night it was clear enough that some winter stars in and around Orion actually showed up in the sky.<br />
<br />
This is a 2-exposure blend with the Canon 6D MkII at ISO 800 and Rokinon 14mm SP f/2.5 lens stopped to f/4.5. The ground is 1/8-second; the sky is 3.2 seconds. An Orton glow effect added to the ground with Luminar Flex.

  • The Canadian Pacific Holiday Train at its last stop on its 2019 tour, in Gleichen, Alberta, near the Siksika Nation and near home, on December 18, 2019. At each stop, performers present a concert from the stage car to the trackside audience, and raise funds for charity. On this night it was clear enough that some winter stars in and around Orion actually showed up in the sky, though for Orion I blended in a longer 3.2-second exposure to make his stars show up better. <br />
<br />

<br />
This was from a viewpoint overlooking the Bow River on the Siksika Nation in southern Alberta. <br />
<br />
Orion is above the river with Sirius in Canis Major just rising. Aldebaran in Taurus and the Pleiades are at top right. At top is the star Capella and the constellation of Auriga. At left are Castor and Pollux in Gemini. Above the lights is Procyon in Canis Minor. The Beehive Cluster is at left.<br />
<br />
The low Moon behind the camera to the right added a warm “bronze hour” tint to the landscape.<br />
<br />
This is a blend of untracked exposures for the ground and tracked exposures for the sky, using the Star Adventurer tracker. The ground and sky are each stacks of 4 x 1-minute exposures with the 15-35mm Canon RF lens at 15mm and f/2.8 and on the Canon EOS Ra camera at ISO 800.

Orion is above the trees with Aldebaran in Taurus and the Pleiades above him. At top left is the star Capella and the constellation of Auriga. At left of centre are Castor and Pollux in Gemini. Just rising amid the trees is Procyon in Canis Minor. Sirius and Canis Major had not yet risen. The timing nicely captures 4 of the sky’s best star clusters in a row across the sky, with the Beehive just rising at lower left, the Hyades at upper right, and the Pleiades at top. Between the Hyades and the Beehive is the small binocular cluster in Gemini, M35, but visible in this wide-angle view. <br />

  • A 360° panorama of the spring sky over the Badlands of Dinosaur Provincial Park, Alberta, on March 29, 2019, with the winter Milky Way and constellations setting at centre, and the spring constellations filling the sky at left and right. At centre is also the tapering pyramid-shaped glow of the Zodiacal Light, which continues to the left across the sky as the Zodiacal Band and brightening at far right above the horizon as the Gegenschein. Urban sky glows from Brooks and Calgary mar the horizon with white and yellow glows. Mars is just below the Pleiades at centre in the Zodiacal Light. <br />
<br />
The panoroma projection stretches out the sky at top near the zenith, so the Big Dipper at right. is distorted. <br />
<br />
This is a panorama of 12 segments taken with the 14mm Sigma Art lens and Nikon D750 in portrait orientation, all for 30 seconds at f/2.8 and ISO 4000. Taken at 30° spacings. Stitched with PTGui. I added a mild Orton glow effect with Luminar 3 plugin.

  • Orion, Sirius, Taurus, the Pleiades, and the winter sky setting in the spring twilight sky, March 29, 2019, at Dinosaur Provincial Park, Alberta.  Lingering twilight adds the blue sky naturally, during the last moments of a “blue hour.” <br />
<br />
This is an HDR and luminosity mask blend of 6 exposures to retain detail in the dark foreground and bright twilight. The sky and stars come from a single exposure, with the exception of a shorter exposure blended in for the bright twilight area. A little unintended light painting from headlights from another visiting photographer painted the hill to the left. All with the Sigma 24mm Art lens and Nikon D750. An soft focus Orton glow effect added to the ground with Luminar plugin.  This is a good demo of Rule of Thirds and leading lines composition elements.

Below the left star of the Belt, Alnitak, is the famous Horsehead Nebula, while above it is NGC 2024, aka the Flame Nebula. At very top left is Messier 78, while part of Barnard’s Loop arc across the field at left. The field is filled with other faint red emission and blue reflection nebulas. The large loose open cluster Collinder 70 surrounds the middle star of the Belt, Alnilam. <br />

  • The Canadian Pacific Holiday Train under the stars of winter, including Orion, Taurus and – just rising at lower left – Sirius in Canis Major. The train was stopped in Gleichen, Alberta, on December 7, 2018, at 10 p.m. for a half hour stop and musical show with Terri Clark (on stage here) and band. Hundreds of people attended.<br />
<br />
This was a challenge to shoot, to be sure, what with the town lights, the floodlights lighting the stage area, and the lights from the train itself, requiring exposures of a fraction of a second, while the stars needed several seconds. This is a blend of two exposures of 0.4 and 2 seconds, both at ISO 400 at f/2.8. And with the Sony a7III and Laowa 15mm lens. Layers blended with conventional  masks. Plus for the long exposure I covered the lens with my hand to hide the lower area of the image to prevent the lights from glaring too much into the sky, but that helped only a bit. <br />
<br />
And I had fun applying Orton glow effects with ON1 and Luminar, to the ground and to the sky, plus using the Astronomy Tools actions to add the diffraction spikes on the stars and some of the train lights. A duplicated sky layer blended in with Linear Dodge punches up the stars and sky glows around them. So, yes, this all makes for a processed scene to be sure, but it’s Christmas! <br />
<br />
And the sky is real and has not been “cut and pasted” into the scene. The location of the sky at 10 pm was perfect for including the main winter stars above the westbound train.

<br />
Hundreds of people attended, with the show going on down the train at the stage car. I’m standing near the front of the train to take in as much of its light display as possible, to contrast it with the stars overhead on this very clear December night. <br />

  • A collage of the northern hemisphere winter sky, with a background mosaic of the sky, surrounded by telescopic close-ups of the brightest stars in that sky. <br />
<br />
The background mosaic is made of 8 segments, in two columns of 4 rows, with generous overlap. Each segment was made of 4 x 2.5-minute exposures stacked with mean combine stack mode to reduce noise, plus 2 x 2.5-minute exposures taken through the Kenko Softon filter layered in with Lighten belnd mode to add the star glows. Each segment was shot at f/2.8 with the original 35mm Canon L-series lens and the filter-modified (by Hutech) Canon 5D MkII at ISO 1600, riding on the iOptron Sky-Tracker. All stacking and stitching in Photoshop CC 2015. The soft diffusion filter helps bring out the star colours in this area of sky rich in brilliant giant stars.  I shot the segments on a very clear night on December 5, 2015 from the Quailway Cottage at Portal, Arizona.<br />
<br />
The close-ups are each stacks of 2-minute and 30-second exposures with a 130mm f/6 apo refractor and Canon 6D Mark II at ISO 800. taken November 19, 2018 from home. A waxing gibbous Moon provided the blue background sky.

  • Orion and the stars of winter setting over the downtown core of Calgary, on April 19, 2018.<br />
<br />
I shot this from Tom Campbell Park, looking west. Venus is the bright object at far right; Sirius is the bright star at far left, with both flanking the skyline. Above is the waxing crescent Moon. The Pleiades is above Venus. <br />
<br />
This is a stack of 4 x 2-second exposures taken for a time-lapse and star trail set, all with the 24mm Sigma Art lens at f/2.8 and Nikon D750 at ISO 400. The Moon is from an HDR-blend of shorter exposures so its disk does not overexpose into a bright blob in the thin cloud. It better depicts the scene the way the eye saw it, though in this case the camera is picking out stars better than the eye could with all the foreground lighting and glare. <br />
<br />
No light pollution filter was employed.
    Orion Setting over Calgary Skyline (...jpg
  • 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.

<br />
<br />
To be artistic I added a “Misty Land” Orton-style glow effect with Luminar. And diffraction spikes on the brightest objects with Astronomy Tools actions.<br />
<br />
Taken from near home in southern Alberta, with a lot of snow only now beginning to melt. <br />

Orion is at centre with his Belt pointing down to Sirius and up to Aldebaran in Taurus with the Pleiades. Procyon and Pollux and Castor are at upper left. <br />
<br />
There was a lot of snow on the ground this year in early April. This looks more like a winter scene than spring. <br />
<br />
This is a composite of a single 25-second untracked exposure for the sky, and a stack of 8 x 25-second exposures for the ground, averaged in-camera using the Canon 6D MkII Multiple Exposure Average function. This smooths noise. All at f/2.8 with the Rokinon SP lens and Canon 8D MkII at ISO 1600.

  • Orion on a clear winter night in downtown Calgary and shining over the pedestrian Peace Bridge  over the Bow River. I shot this on January 20, 2018. <br />
<br />
This is a real scene, though the sky is a single longer exposure of 6 seconds at ISO 400, while the ground is a blend of 4 exposures from 1.6 to 8 seconds at ISO 100, all at f/2.8 with the 24mm Sigma Art lens and Nikon D750. A NISI Natural Night filter helped cut through light pollution and provide a more natural blue sky, though this was a moonless night. The ground images were blended with luminosity masks generated with ADP Pro v3, to prevent the lights on the bridge from blowing out too much. <br />

<br />
The key added element was the use of a NISI Natural Night light-pollution reduction filter in a test to see how well it brought out nebulosity and suppressed sky glow and gradients compared to a filterless shot. It did work and provided more nebulosity and reduced gradients toward the bottom of the frame. <br />

I shot this from Crescent Road on the north bank of the Bow River, with Orion nearly due south as high as it could get. So this is a real scene, not a faked composite with a sky shot someplace else or at some other time layered in. <br />
<br />
However, the view was helped by the use of a NISI Natural Night light pollution filter on the lens which helped filter out the yellow emission lines from sodium vapour lights, and rendered the sky a more pleasing blue tint (this is not from moonlight). <br />
<br />
The faintest stars are about magnitude 7.5, not bad from a city site, though this was a very clear, haze-free night, the sky factor. <br />
<br />
In addition, the sky is a longer single exposure of 10 seconds at f/2.5 and ISO 400 (which brought out the stars more but overexposed the skyline), while the skyline is a stack of 4 x 3-second exposures at f/2.8 and ISO 400 (to better expose for the bright lights). This composited accommodated the huge range of brightness of the scene. something like an HDR blend. <br />
<br />
I shot this with the 24mm Sigma Art lens and Nikon D750. <br />
<br />
I added the star diffraction spikes for artistic effect using Astronomy Tools actions.

  • The stars, Milky Way, and constellations of the northern winter sky, including the Winter Hexagon of bright stars, and the Winter Triangle of Betelgeuse, Sirius and Procyon, in a wide-angle shot from the snowy horizon to Capella nearly at the zenith. Orion is at centre. His Belt point up to Taurus and down to Canis Major and Sirius. The Beehive Cluster is at lower left, while the Pleiades is at upper right. <br />
<br />
There are deer tracks in the snow. <br />
<br />
With the 14mm Sigma Art lens at f/2 for 20 seconds at ISO 3200, with the ground a stack of 4 exposures to smooth noise. All untracked. Shot from home January 13, 2018, on a mild winter night at -8° C or so. Diffraction spikes added with Astronomy Tools actions.

  • The constellation of Orion the Hunter, at right, and his two Hunting Dogs and their brightest stars: Procyon in Canis Minor (at left) and Sirius in Canis Major (at bottom).<br />
<br />
The winter Milky Way runs from top to bottom through Monoceros and Canis Major.<br />
<br />
The red arc is Barnard’s Loop, an interstellar bubble blown by hot stellar winds from young stars in the Orion complex. The red patch at upper centre is the Rosette Nebula in Monoceros. The Orion Nebula is overexposed right of centre. <br />
<br />
This is a stack of 3 x 2-minute exposures with the 35mm lens at f/2.5 and filter-modified Canon 5D MkII at ISO 1600, on the Star Adventurer Mini tracker. <br />
<br />
A 4th exposure through the Kenko Softon A filter adds the star glows for accentuating colour and the visibility of the brightest stars.<br />
<br />
Shot from Quailway Cottage in southeast Arizona, December 15, 2017.
    Orion and His Dog Stars (35mm 5DII).jpg
  • Orion and Sirius rising over the Peloncillo Mountains of southwest New Mexico, on a clear night in December in the early evening. The Belt stars of Orion point down to Sirius, the Dog Star. <br />
<br />
The long tracked exposures and the filter-modified camera brings out the red nebulsity in the area, such as Barnard’s Loop, the Lambda Orionis bubble at top, the Horsehead Nebula area near the Belt, the very bright Orion Nebula, and the intense Rosette Nebula at left. <br />
<br />
Airglow add some bands of red and green toward the horizon. <br />
<br />
This is a mean-combined stack of 5 tracked exposures for the sky, each 2.5 minutes at ISO 1600, and 3 short 30-second but also tracked exposures for the ground at ISO 6400, again mean combined to smooth noise. As the ground exposures were also tracked, the ground is blurred slightly. <br />
<br />
An additional short exposure taken through a Kenko Softon A filter blended in with Lighten mode adds the star glows for accentuating star colours and the prominence of bright stars. <br />
<br />
All with the 35mm Canon L-series lens at f/2.5 and Canon 5D MkII camera, on the Star Adventurer Mini tracker, and shot from the Quailway Cottage in SE Arizona.
    Orion & Sirius Rising over Pelon...jpg
  • The constellations of Orion the hunter and Eridanus the river (at right), with the bonus of a Geminid meteor below Orion, through Lepus the hare. <br />
<br />
This is a stack of 5 x 2-minute exposures with the 35mm Canon lens at f/2.5 and Canon 5D MkII at ISO 1600, including one with the meteor, plus an additional exposure through the Kenko Softon filter layered in to add the star glows. <br />
<br />
Taken from Quailway Cottage in Arizona, with the Star Adventurer Mini tracker.
    Orion and Eridanus (35mm 5DII).jpg
  • A composite showing the 2017 Geminid meteors streaking from the radiant point in Gemini at upper left, above the blue-white star Castor. 2 or 3 meteors are not Geminids as their paths do not project back to the radiant, but I have left them in regardless, as an illustration. <br />
<br />
This also illustrates how the meteor paths are shorter closer to the radiant and lengthen away from the radiant. <br />
<br />
This is a stack of 43 exposures, each 1-minute with the 24mm Canon lens at f/2.5 and filter-modified Canon 5D MkII camera at ISO 6400, set fast to pick up the fainter meteors. These were 43 exposures with meteors (some with 2 or 3 per frame) out of 455 taken over 5 hours. <br />
<br />
Orion and its red nebulas are at right. The Beehive star cluster, M44, is at lower left. Sirius is the bright star at lower right.<br />
<br />
The camera was on a Star Adventurer Mini tracking unit, so all the frames more or less aligned when stacked with the meteors in the correct relative position. The background sky comes from just one of the exposures. All the other frames are masked to show just the meteor.<br />
<br />
Taken December 13/14, 2017 during the very active 2017 Geminid meteor shower, and shot from Quailway Cottage in southeast Arizona, near Portal.
