13999539 - A moonlit scene of the Blakiston Valley in Waterton Lakes National Park,Alberta,May 29,2023. The waxing gibbous Moon is in the frame at top,providing the illumination and lighting Blakiston Creek. Moonlight is the same colour temperature as sunlight,so in a long exposure like this,a scene looks like daylight.13999527 - This is a panorama of the ground and sky framing the badlands of Dinosaur Provincial Park,in the Red Deer River valley in Alberta,with the summer sky above filled with three dozen meteors from the annual Perseid meteor shower,of August 12,2023. The meteors all appear to be streaking away from the radiant point in Perseus at far left. The location is the upper viewpoint near the Park Entrance,and looking northeast to southeast. The lights in the valley below are from the campground and service centre. The one glaring sodium vapour light should be removed or at least shielded. The brightest hori13999168 - The rising Full Moon of May 5,2023,coming up over the Red Deer River near East Coulee,Alberta. The Moon is illuminating the water with a fine golden glitter path.13900618 - The galactic centre area in Sagittarius (at left) and Scorpius (at right) low in the south on a summer night at Dinosaur Provincial Park, Alberta. This was June 30/July 1, 2022. Being just 10 days after summer solstice and at latitude +50° North, the sky even to the south still has a blue tint from all-night twilight. I made no attempt to neutralize the sky colouration. In addition, some haze from smoke discoloured the sky and reduced transparency and contrast low in the sky.13900215 - The Andromeda Galaxy (aka Messier 31) and the stars of Andromeda rising over moonlit formations at Dinosaur Provincial Park, Alberta. Illumination is from the waxing gibbous Moon, low in the southwest so it is providing a warm light. This is an example of a "deepscape" - a nightcape with a telephoto lens to also record a deep-sky object in the frame above the horizon. However, moonlight prevents the galaxy from showing up as well as it would in a dark sky.13900075 - Circumpolar stars trails over Castle Mountain in Banff, Alberta. Taken July 23, 2010 from Castle Cliffs viewpoint on Bow Valley Parkway. A stack of 160 25-second exposures with Canon 15mm lens at f/4 and Canon 7D camera at ISO 640. Taken over 2 hours. Full Moon light provided the illumination.13899769 - VLA radio telescope array, near Socorro, New Mexico.13899576 - The galactic core area of the Milky Way over Maskinonge Pond in Waterton Lakes National Park, Alberta. Jupiter is the bright object at left, with Saturn dimmer to the left (east) of Jupiter. In the summer of 2020 the two planets were close together in the summer sky. Jupiter provides the glitter path on the water. Antares and Scorpius are to the right. Sagittarius is at centre. This was July 13-14, 2020.13899539 - The Big Dipper and Ursa Major over moonlit formations at Dinosaur Provincial Park, Alberta. Illumination is from the waxing gibbous Moon, setting in the southwest so it is providing a warm "bronze-hour" light.13899470 - Orion setting in March over Mt Temple near Lake Louise in Banff National Park, Alberta.13899459 - The summer Milky Way over the Log Cabin at the Reesor Ranch, July 16, 2013. This is a stack of 5 x 4 minute tracked exposures for the sky + one 4 minute untracked exposure for the ground. Each at f/2.8 with the 15mm lens and Canon 5D MkII at ISO 1600.13899423 - The galactic core area of the Milky Way over Waterton Lakes National Park, Alberta with the pairing of giant planets from summer 2020. Jupiter is the bright object at centre, with Saturn dimmer to the left (east) of Jupiter. In 2020 the two planets were close together in the summer sky. Sagittarius is at right. The Prince of Wales Hotel is the bright light source. This was July 13-14, 2020.13899397 - Venus as an "evening star" in the deepening twilight of solstice eve on December 20, 2021.13899099 - A panorama of the glacier-fed Athabasca River and peaks around Mount Fryatt in Jasper National Park, as the Milky Way is setting and the waning gibbous Moon rising, lighting the peaks of the Continental DIvide with lunar alpenglow. Mount Fryatt is at centre, while to the right is Mount Geraldine, and to the left are Brussels Peak and Mount Christie. Jasper is one of the world's largest Dark Sky Preserves.13898290 - The summer Milky Way over and reflected in the relatively calm water of Pyramid Lake in Jasper National Park, on a mid-October night. The Jasper Sky Tram adds the lights on Whistler Peak. Bands of airglow tint the sky with red. Lights from the Jasper townsite, still mostly unshielded sodium vapour lights as of 2022, add the skyglow at left. Altair is the bright star at top. The red Lagoon Nebula is just setting behind the mountain skyline. The slight wind rippled the water enough to prevent a perfect reflection.13898251 - The Pleiades star cluster and the other stars of Taurus rising above Mount Kerkeslin at Athabasca Falls, in Jasper National Park, Alberta, October 22, 2016. The sky is brightening with the rising waning Moon off frame at left. Some cloud adds star glows and hazy patches to the sky.13898054 - The International Space Station (ISS) flying away to the east over the moonlit badlands formations at Dinosaur Provincial Park, Alberta, on July 12, 2022, just before local midnight. The image frames the stars of Cassiopeia (upper left), Perseus (at left), Andromeda (centre) and Pegasus (at right). A couple of other fainter satellites are also in the image. Light from the almost Full Moon illuminates the sky blue and foreground a warm colour.13897921 - Mars (near its brightest just past closest approach) shining over Two Jack Lake and Mr. Rundle in Banff National Park. Saturn is left of Mars near the trees, Antares below in the trees. This was June 3, 2016. Wind prevented reflections on the water.13897897 - The aurora of February 7, 2014 seen from Churchill, Manitoba at the Churchill Northern Studies Centre, in a view looking southeast over the abandoned Churchill Rocket Range, with the 10-22mm lens. This is taken from the second floor viewing deck at the CNSC. This is a 15-second exposure at f/3.5 and ISO 1600 wth the Canon 60Da camera. Jupiter and Gemini are at top and Orion at lower right. The gibbous Moon is just off the frame at upper right.13897642 - 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.13897568 - Orion Rising with trails13897522 - Sunset colours over White Sands National Monument, New Mexico, December 10, 2013. Venus is at left of centre. This is an HDR (High Dynamic Range) stack of 7 exposures at 2/3 stop increments from -2 to +2 EV, processed first with ACR then with Photomatix Pro. Images taken with the 14mm Rokinon lens at f/4 and Canon 5D MkII at ISO 100. While colour vibrancy has been enhanced the colours to the eye were quite vivid. The HDR technique brings out details in the dark ground while preserving the bright sky.13897514 - The Milky Way over Herbert Lake, Banff, Alberta, near Lake Louise. Mount Temple is glacier-clad peak at left. A single exposure of 40 seconds at f/2.8 with 16-35mm lens and Canon 5D MkII at ISO 1600. No Moon, and taken in late twilight.13897433 - Curtains of aurora over the Ramparts falls on the Cameron River near Yellowknife, NWT, on Sept 8, 2019.13897404 - Photographer Stephen Bedingfield is shooting the Northern Lights at the Ramparts waterfalls on the Cameron River, September 8, 2019. The Big Dipper is at centre. The aspen trees are nicely turning colour.13897397 - The summer Milky Way overhead and through the Summer Triangle stars in July, looking up through trees in Banff National Park at Herbert Lake. Deneb is at top left, Vega at top right, and Altair is at bottom. The bright Cygnus star cloud is obvious. As are the dark lanes in the Milky Way, including the Funnel Nebula at top, aka Le Gentil 3.71444198 - At night at Alexanderplatz in Berlin, Germany.13999548 - This is a 180° panorama of the night sky over the hoodoo formations of Bryce Canyon National Park,Utah,at Sunset Point. The panorama extends from the northeast (at left) where the autumn Milky Way is rising,to the southwest (at right) where the summer Milky Way and galactic core in Sagitarius are setting. This was October 11,2023. The most notable feature is the prominent arc of green airglow bands across the eastern sky,a natural sky phenemenon. Perseus is at left in the Milky Way. At top at left is the Andromeda Galaxy,M31. Below it is the blue Triangulum Galaxy,M33. Jupiter is the bright ob13999161 - The Full Moon of July 31,2023 rising at the end of a long line of high tension towers across the prairie near Milo,Alberta. Some smoke in the air made the rising Moon even redder than normal,making it look like an eclipsed Moon. This night the alignment of the rising point of the Full Moon coincided with the angle of the powerlines off to the southeast at 135° azimuth.13998865 - The rising Full Moon of May 5,2023,coming up over the Red Deer River near East Coulee,Alberta. This is a panorama of the Badlands scene,with the site planned with The Photographer's Ephemeris app.13998394 - This is the northern hemisphere autumn Milky Way from Auriga (at bottom) to Cygnus (at top,at the zenith) rising into the northeast over the hoodoo formations of Inspiration Point,at Bryce Canyon National Park,Utah.13900423 - The late winter evening Zodiacal Light, as shot at Dinosaur Provincial Park, Alberta, February 28, 2017. The Light is the glow from sunlight reflecting off cometary dust particles in the inner solar system. It is not an effect of twilight. It is best visible in the evening from northern latitudes in late winter and spring.13900420 - The Northern Lights over the waterfalls known as the Ramparts on the Cameron River east of Yellowknife, NWT, on September 8, 2019. The aspen trees are turning yellow on this September evening. This is looking northeast toward Perseus and Andromeda. M31 is at top centre.13900415 - The summer Milky Way and Summer Triangle stars rising in the east at Dinosaur Provincial Park, Alberta on May 14, 2018.13900394 - 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.13900300 - 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.13900298 - A 360° ground to zenith panorama of the Mt. Edith Cavell area from the Trail of the Glacier pathway, at the footbridge crossing Cavell Creek. I shot this at twilight, just after sunset. It is a stitch, with PTGui software, of 8 segments at 45° spacings with the 15mm full-frame fish-eye lens and Canon 6D. Each was 0.4 seconds at ISO 100 and f/4. (I should have stopped down some more!)13900152 - 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.13900144 - The Big Dipper reflected in the still waters of the lake at Police Outpost Provincial Park, in southern Alberta, on September 26, 2016, with an aurora to the north at right. Only in autumn can one shoot the Dipper reflected in the water in the evening sky, as it is then riding low along the northern horizon. This is from a latitude of 49° N where the Dipper is circumpolar. It is also called the Plough in Great Britain.13900110 - A curtain of aurora sweeps over the houseboats moored on Yellowknife Bay in Yellowknife, NWT, on September 11, 2018.13900092 - An overhead pass of the International Space Station in a bright moonlit sky on the night of May 31/ June 1, 2015, with the gibbous Moon in to the south, below. The view is looking south, with the ISS travelling from right (west) to left (east) over several minutes. This was the second pass of a 4-pass night, May 31/June 1, starting at 12:44 am MDT this morning.13900083 - 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.13900052 - The arc of Northern Lights starting a show in the deep twilight over Prelude Lake on the Ingraham Trail near Yellowknife, NWT. This was September 9, 2019. Light from the waxing gibbous Moon behind the camera also illumimates the scene. The autumn colours make for a good contrast with the sky colours. This was from the lookout point above the lake and main parking area and boat launch.13900025 - The rising autumn stars and constellations over and reflected in the lake at Police Outpost Provincial Park, in southern Alberta, on September 26, 2016. The stars of Auriga and Taurus are rising, including the Pleiades at upper right. Capella is the bright star above right centre; Aldebaran is below right in the sky. Both are reflected in the still water, along with the Hyades and Pleiades star clusters. A mild aurora is at left.13899973 - Bright planets Mars (reddish at left) and Jupiter (right, over Bow Glacier) over Bow Lake, in Banff, Alberta, and reflecting in the water in glitter paths on the lake.13899797 - Circumpolar star trails and aurora over the Red Deer River, Alberta from the Orkney Viewpoint north of Drumheller on May 5, 2018.13899753 - One of the 27 antennas of the Very Large Array (VLA) radio telescope complex in New Mexico (with others in the distance at lower right) illuminated by moonlight, on December 13, 2013, peak night for the Geminid meteor shower. A single exposure of 30 seconds with the Rokinon 14mm lens at f/2.8 and Canon 5D MkII at ISO 800. Orion is rising a lower centre. The Moon is the bright object at upper right. The Pleiades and Hyades are above centre.13899655 - The Big Dipper over Castle Mountain, Banff, on a partly cloudy and dewy night. Taken as part of a 150-frame time-lapse. With the 24mm lens and Canon 5D MkII for 30 seconds at f/2 and ISO 1600.13899634 - The Milky Way and galactic core area over Mount Andromeda (centre), Mount Athabasca (left) and the Athabasca Glacier (right) at the Columbia Icefields, on a very clear night July 27, 2020.13899464 - Orion and the winter stars and constellations rising in the light of a first quarter Moon on December 3, 2019. The vertical format sweeps up the Milky Way.13899443 - The rising of the nearly Full Moon on October 8, 2022, the Hunter's Moon. This was the evening before the official day of Full Moon. Jupiter is just at upper right.13899184 - The stars setting into the west over the Columbia Icefields and Athasbasca (left) and Stutfield (right) glaciers, and Snowdome peak. I shot this Sept 6 under very clear skies and a bright waxing gibbous Moon off frame at left. I shot this from the moraine at the upper parking lot.13899140 - Reflections of the Northern Lights in the calm and misty waters of Madeline Lake on the Ingraham Trail near Yellowknife, NWT on Sept 7, 2019. This is one of a series of “reflection” images. Altair is at left.13899127 - 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.13899082 - The Milky Way reflected in the unusually calm waters of Middle Waterton Lake from Driftwood Beach, in Waterton Lakes National Park, Alberta, Canada. The Park is an International Dark Sky Preserve, along with Glacier National Park in the U.S. The Park is also a U.N. World Heritage Site.13899081 - The Northern Lights shot at the old Larson Ranch site in the Frenchman Valley at Grasslands National Park, Saskatchewan, August 27/28, 2014. The pioneer cabin was the home of the legendary western author and movie star Will James, born Ernest Dufault in Quebec. He lived in this cabin when he worked the ranches in the area. The aurora was excellent this night. This is a single 1-minute exposures at ISO 2500 with the 15mm full-frame fish-eye lens at f/3.2 and the Canon 6D.13899024 - The nearly Full Moon (0ne day before Full) rising at the end of Bow Lake, with purple flowers (Purple Saxifrage?) in the foreground. Taken August 9, 2014. This is an HDR High Dynamic Range stack of 5 exposures at 2/3rds stop intervals, with the Canon 16-35mm lens and Canon 6D at ISO 400.13898847 - The old Atlas Coal Mine near East Coulee, Alberta, now a museum and tourist attraction. This is a composite of 20 x 1 minute exposures with the Canon 5D MkII and 16-35mm lens at 16mm and f/2.8, and ISO 1250. Taken June 27, 2013. While the Moon was up it was in some cloud and most of the illumination of the foreground comes from a sodium vapour light just off camera at right. Images stacked with StarCircleAcademy's Advanced Stacker Actions, Comet Streaks option.13898812 - Comet NEOWISE (C/2020 F3) over the still waters this night of Crawling Lake in southern Alberta. This was early in the evening with the sky still brightly coloured with twilight. The comet was in the southern part of Ursa Major between the pairs of stars called Tania and Talitha. The clouds that were present nicely framed the scene and reflected in the water as well. The comet was too high to be visible as a reflection at this time.13898662 - A panorama of noctilucent clouds to the northwest just before midnight on the evening of July 10-11, 2022, over a hill and red farm road in southern Alberta, Canada.13898308 - The stars of Ursa Major, the Great Bear, over the waters of Peyto Lake, Banff, in deep twilight. Arcturus in Böotes, the Bear Driver, is setting over the peak at left. Ursa Major contains the seven stars that make up the Big Dipper, aka the Plough or the Wagon. This was October 13, 2022 on a very clear night in the Rocky Mountains.13898150 - The late-night spring Milky Way from my rural backyard in Alberta (latitude 51° N) on a fine May night in 2020, with the waxing Moon just setting and lighting the landscape and sky. Jupiter (brightest) and Saturn to the east (left) are just rising together at left, east of the Milky Way. West of the galactic centre at right is red Antares in Scorpius. The Small Sagittarius and Scutum starclouds are prominent at centre, with their various Messier nebulas and star clusters visible.13898130 - This is a blend of exposures showing all the satellites (and a few aircraft) recorded by the camera on a late spring night (June 1-2, 2022) from latitude 51° North, from where and when satellites are illuminated all night long and can be seen all through the short night. This is looking almost due south.13898058 - The Milky Way from northern Sagittarius to southern Cygnus, above the mountains of Waterton Lakes National Park; Alberta, Aug 31, 2013. This is a stack of 4 x 3 minute exposures at f/2.8 with the 24mm lens and Canon 5D MkII at ISO 1600.13897971 - Galaxy and glacier! This is a vertical panorama of the Milky Way Galaxy over Lake Louise and Victoria Glacier in Banff National Park, Alberta. The Summer Triangle stars of Vega, Deneb and Altair are at centre. The Scutum Starcloud is just above and setting over Victoria Glacier. The dark lanes of interstellar dust — stardust! — weave among the bright star clouds of the Milky Way.13897968 - A 360° panorama of the landscape and skyscape at Grasslands National Park, Saskatchewan, Canada, taken August 25, 2014. The Milky Way arches overhead from south to north at right, and the last vestiges of twilight light the western sky at left, providing a natural backdrop for the silhouette of the photographer gazing wistfully into the distance! Some green bands of airglow also light the sky, but only a few farm lights from outside the boundaries of the Park mar the landscape in this darkest of Dark Sky Preserves in Canada. I shot this from the Eagle Butte Loop Trail at the end of the 70 Mile13897956 - Gibbous Moon over Banff townsite, Banff National Park, Alberta, Canada. Taken July 29, 2012 with Canon 7D and 10-22mm lens at ISO 100, f/6.3 and metered. Taken in twilight. Peak is left is Mt. Rundle. Taken from Mt. Norquay viewpoint overlooking town looking south.13897949 - The rising nearly Full Moon of December 19, 2021, above a snowy prairie scene with a lone tree, and the cold blue twilight lighting the snow, contrasting with the pink of the Belt of Venus above. The Moon is partly in a narrow band of cloud and is exhibiting a slight green flash phenomenon on its distorted upper edge, and red limb on its lower edge from atmospheric dispersion.13897937 - A selfie of me shooting time-lapses and tracked Milky Way images at the 76 Ranch Corral site at Grasslands National Park, August 27, 2019. Taken for use as a book cover. High cloud and a dark aircraft contrail drifting through added the star glows and the dark streak. Jupiter, at right, and Saturn, at left, flank the Milky Way. Altair is the bright star at top.13897860 - The core of the Milky Way in Sagittarius low in the south over the Frenchman River valley at Grasslands National Park, Saskatchewan. This is from the 76 Ranch Corral site. Grasslands is a Dark Sky Preserve.13897834 - A composite stack of 12 images taken June 11/12, 2017 of the waning gibbous Moon tracking low across the southern sky on a June nght, from moonrise at left at 11:30 pm to when it began to leave the frame at right at 4 a.m. and when the sky was brightening with dawn. Images are at 25-minute intervals. The sky is blue here from the moonlight.13897676 - The galactic centre area of the Milky Way in Sagittarius behind the grand old barn near home in southern Alberta, on June 30, 2019. Illumination of the barn is from twilight to the north, but also from light pollution skyglow from the west off frame at right. The sky is blue from the perpetual summer twilight at this time of year.13897546 - Orion rising in the moonlight over an old fence and farm implement at my house in southern Alberta, on a very cold and frosty -20° C night on January 3, 2017. Illumination is from the waxing crescent Moon.13999714 - The Blakiston Valley in Waterton Lakes National Park,in Alberta,Canada,in a panorama captured by moonlight,May 29,2023. Illumination is from the waxing gibbous Moon just off frame at top.13999152 - The quarter Moon,(in Leo) and planets Venus (brightest at right) and Mars (dim and upper left of Venus) in the late evening twilight over the front ranges of the Rocky Mountains. The stars Castor and Pollux in Gemini are above Venus. This was May 27,2023,from the Sierra Cabins West property near Lundbreck,Alberta,shot during a workshop as part of the program for the Lightchasers Conference held in Pincher Creek,Alberta. Illumination is by moonlight and some car headlights.13999115 - A moonlit scene of yellow balsamroot wildflowers blowing in the wind on a moonlit night in the Blakiston Valley in Waterton Lakes National Park,Alberta,May 29,2023. Blakiston Creek winds below toward the Waterton River. The waxing gibbous Moon just off frame at top provides the illumination. Moonlight is the same colour temperature as sunlight,so in a long exposure like this,a scene looks like daylight13998900 - The northern sky over the Hoodoos badlands formations in the Red Deer River valley near Drumheller,Alberta,on a night with some aurora tinting the sky yellow and magenta,with a touch of blue. The foreground is lit partly by a yardlight nearby and car headlights. The Big Dipper is at left; Polaris and the Little Dipper are above centre; the W of Cassiopeia is at upper right.13998841 - This is a panorama of the colourful evening twilight sky over the Badlands of the Red Deer River,Alberta,taken from the Horsethief Canyon viewpoint north of Drumheller on the Dinosaur Trail. The very thin crescent Moon is in the photo,but tough to see. It is a pale crescent very low in the orange glow to the right of the grain bins at far left.13998730 - The rising Full "Wolf" Moon of January 6,2023 over the Badlands of Horseshoe Canyon,near Drumheller,Alberta. The sequence demonstrates the changes in colour of the rising Moon from atmospheric absorption,and changes in its shape from atmospheric refraction.13998597 - The Hoodoos formation near Banff,Alberta,on the Tunnel Mountain Drive,overlooking the Bow River and Mount Rundle,with the stars and Milky Way in the sky. Illumination is by starlight,twilight sky colours,and lights from Banff in the distance. The sky is bright and blue with summer twilight,and from the waxing Moon low in the sky behind Mount Rundle.13998459 - Venus in the evening twilight over Lundbreck Falls on the Crowsnest River,near Pincher Creek,Alberta on May 28,2023.13998361 - The rising Full Moon of January 6,2023 over the Badlands of Horseshoe Canyon,near Drumheller,Alberta. Here the Moon is set in the pink Belt of Venus and with dark blue crepuscular rays (or more correctly,anti-crepuscular rays) converging on the point directly opposite the Sun. The rays are shadows cast by clouds in the west,which parted enough for a few moments for the setting Sun to light the foreground,making for a colourful contrast between ground and sky.13900600 - Full Moon rising at fall equinox, over Vermilion Lakes, and beside Mt. Rundle, Banff National Park, September 1995.13900573 - The Hoodoos in the Red Deer River valley on Highway 10 east of Drumheller. Taken September 21, 2013 with the Canon 5D MkII and 24mm lens with a single 30-second exposure. Light from waning gibbous Moon provided the illumination.13900496 - An arc of modest aurora borealis (Northern Lights) across the northern horizon, above a prairie meadow in the light of a bright waxing gibbous Moon, a day before Full. This was just after midnight on July 11/12, 2022 when the sky was also still lit by summer twilight colours, and with a weak display of noctilucent clouds also visible low in the northwest at left. The auroral curtains exhibit the usual green band and rays, but also upper altitude reds and purples and a faint blue tint at the very tops where the aurora is lit by the Sun. The aurora was never bright this night (Kp Index was 3 or 13900221 - A subtle and pastel aurora borealis (Northern Lights) in the northeast, above a prairie meadow at "Lone Tree Hill". The foreground and sky are lit by a bright waxing gibbous Moon, a day before Full, shining in the south. This was just after midnight on July 11/12, 2022. The auroral curtains exhibit the usual green band and rays, though with shades of green visible, perhaps from hydrogen-beta proton emission as well as oxygen electron emission, but also upper altitude reds and purples and a faint blue tint at the very tops where the aurora is lit by the Sun. The aurora was never bright this nig13900174 - Mars (at left in clouds) and the summer Milky Way over Lake Herbert and reflected in the still waters this night. This is in Banff National Park, Alberta. I shot this July 17, 2018 on a night that gradually clouded up, after a run of two very good nights previous to this.13900130 - Mars and the Milky Way over the tipis at Two Trees area in Grasslands National Park, Saskatchewan on August 6, 2018. Some light cloud added the haze and glows to the planets and stars. Illumination is by starlight. No light painting was employed here.13900093 - An all-sky aurora with green and purple curtains, the night of June 7-8, 2014, starting up about 12:30 and going until dawn. This shot was near its peak, from the old barn site near home in southern Alberta. Foreground illumination is from the aurora and ambient sky -- the Moon had set. The Big Dipper is above the Barn. The purple colour is from blue scatttered sunlight hitting the red tops of the auroral curtains. This was with the 16-35mm lens at f/3.2 for 20 seconds at ISO 1600 with the Canon 6D.13900038 - The rising nearly Full Moon of December 19, 2021, above a snowy prairie scene with a lone tree, and with the cold blue twilight lighting the snow, contrasting with the pink of the Belt of Venus above.13899985 - The Milky Way over Athabasca Glacier and the Columbia Icefields in Jasper National Park, Sept 14, 2014 on a very clear night before moonrise. The centre of the Galaxy area in Sagittarius is setting in the southwest behind the Icefields. The foreground light on the moraines is wash from lights on the Glacier View Inn and Icefields Centre. Other ground illumination on the peaks is from starlight though the tops of the peaks are just being lit by light from the rising waning Moon which is also beginning to light the sky a deep blue. Mt.
