This was on the evening of May 3, 2025, in the deep twilight sky. Mars was passing across the north edge of the star cluster over several nights in early May 2025, but on this night the Moon was also in the scene near Mars, which was then at magnitude +1.14624515 - This is a roughly 180º panorama of the bright aurora, which had peaked at a Kp 6 to 7 level, on the night of May 28/29, 2025, shot from home in southern Alberta. The aurora was starting a post-substorm pulsing or flickering phase at this time. The arc displays some blue pillars and upper curtains from sunlight interacting with the aurora particles.14623955 - This is the 10th magnitude Messier galaxy M109 in Ursa Major, a barred spiral near the bright magnitude 2.4 star Gamma Ursa Majoris or Phecda, in the Bowl of the Big Dipper. While Messier listed it as object #109 in his catalogue in 1783, it did not become officially accepted as a member of the Messier Catalogue (along with other objects over #101) until the 1950s.14623826 - This is a version of the full-colour panorama, here rendered in near monochrome and low contrast to more or less simulate the appearance of the scene and sky as he unaided eye saw it.14623625 - This telephoto lens image frames the two bright open star clusters in Cancer: M44, aka the Beehive, at top, and the smaller Messier 67 below, a fine cluster but often neglected in favour of its larger and brighter companion above. The field is 10º by 15º, so wider than but similar to that of binoculars and these clusters are both fine binocular targets.14623190 - This is pairing of two large and loose open star clusters: NGC 6633 (at right) in Ophiuchus and IC 4756 (at left) in Serpens. They have been called the S-O Double Cluster or sometimes Tweedledum (NGC 6633) and Tweedledee (IC 4756). IC 4756 is also called Graff's Cluster. The pairing is ideal for binoculars.14623111 - This is the 9th magnitude Messier galaxy M61 in Virgo, a bright face-on spiral galaxy. It was observed by Charles Messier in 1779.14622974 - This is the 10th magnitude Messier galaxy M102 (at lower right) aka NGC 5866 in Draco, an edge-on lenticular galaxy. It is paired with the large and more impressive 10th magnitude edge-on spiral NGC 5907 at upper left.14622799 - This frames Saturn (at bottom) and Neptune (at top centre) when they were just less than 1 degree apart (59 arc minutes) on the morning of June 30, 2025. This was in the dawn sky with the sky blue with oncoming twilight. The two planets were about this close together for several mornings in late June and early July 2025 as they move so slowly. Both were in southern Pisces .14622775 - Experience the breathtaking view of the Milky Way arching over the Atlantic Ocean at Punta del Moral, Huelva during a clear night.14622767 - This is a 120º panorama of the Northern Lights across the northern sky on February 26, 2025 during a Kp3-level display. This shows some fine ray structure in the curtains.14622692 - This frames Saturn (at bottom) and Neptune (at top centre) when they were just less than 1 degree apart (59 arc minutes) on the morning of June 30, 2025. This was in the dawn sky with the sky blue with oncoming twilight. The two planets were about this close together for several mornings in late June and early July 2025 as they move so slowly. Both were in southern Pisces.14622689 - A panorama of a brilliant display of noctilucent clouds (NLCs) in the summer sky, June 29-30, 2025, taken from home in southern Alberta. These were unusually bright and obvious in the darkening twilight, across the northern sky. The glowing NLCs shine with an electric blue light and, as here, can exhibit repeating wave structures. They contrast with the dark tropospheric clouds seen in silhouette against the twilight sky. NLCs appear to shine with their own light, though they are in fact reflecting sunlight coming over the pole.14622169 - A fish-eye 360° view of the fine display of Northern Lights on February 25, 2025, during a substorm outburst with bright curtains to the north. The oxygen green curtains show some pink lower fringes from nitrogen emission. This is looking northwest, with the zenith at top of frame. The Big Dipper is right of centre near the zenith; Orion is setting at far left in the southwest.14622105 - Red Mars at bottom left is here forming a straight line with yellow giant star Pollux (at centre) and bluish-white Castor (at top) in Gemini. Mars was passing below the twin stars in early April in its eastward prograde motion, and happened to form an equally-spaced trio for a few nights in early April 2025. Mars was magnitude +0.6, about a magnitude brighter than the stars. The nearly Full Moon lights the sky deep blue.14622032 - This vertical panorama frames the bright winter stars and constellations setting in the twilight over the Bay of Fundy on an early April evening. The 5-day-old waxing crescent Moon shone in Taurus just above Jupiter this night. At top, reddish Mars appears below and left of the pair of stars Pollux and Castor in Gemini. At centre is Orion with its distinctive trio of Belt stars, as well as reddish Betelgeuse above and bluish Rigel below. Taurus is to the right of Orion, with the Pleiades cluster, while Canis Major and its bright star Sirius is to the left. At top right is Auriga and its bright14621932 - This scene captures the total eclipse of the Moon of March 13/14, 2025, with the red eclipsed Moon over Upper Waterton Lake in Waterton Lakes National Park, Alberta. This is looking southeast toward Vimy Peak.14621352 - This shows some subtle blue rays or pillars emanating from a diffuse green aurora on June 2, 2025, as seen at Dinosaur Provincial Park, Alberta. The aurora never took on much form or structure this night and remained a diffuse arc, but it did show some faint blue rays like this, likely caused by the aurora interacting with sunlight at high altitudes, common near summer solstice.14621288 - Bands of aurora to the east and south over the Churchill Rocket Range in the early evening twilight with the sky still deep blue. Orion and Canis Major are at lower centre. Above is Taurus and the Pleiades, with Jupiter in Taurus. At lower right is the old Aerobee rocket launch tower.14620975 - This frames the bright northern winter constellations setting in the twilight over the Bay of Fundy on an early April evening. The 4.5-day-old waxing crescent Moon shone in Taurus just above Jupiter this night. At left of centre is Orion with its distinctive trio of Belt stars, as well as reddish Betelgeuse above and bluish Rigel below. Taurus is to the right of Orion, with the Pleiades cluster, while Canis Major and its bright star Sirius is to the left.14620866 - The great aurora of May 31/June 1, 2025, in a ~240º panorama from northeast at left, to northwest at right, taken as a substorm was hitting, and the sky was lighting up with bright and colourful curtains. Here the curtains had moved mostly to the south, at centre here, after an initial appearance at the start of the night as a diffuse band across the north.14620749 - This frames most of the bright and dark nebulas inhabiting northern Cygnus, the Swan.14477712 - A clear night reveals a sky filled with stars above Canigou mountain and the Pyrenees, seen from the village of Eus in Languedoc-Roussillon.14476905 - Captivating star trails enhance a serene night at Canigo Mountain in the Pyrenees.71485036 - Starry sky over the Faro de Punta Teno at dusk, Santa Cruz de Tenerife, Spain 71485035 - The beautiful Faro de Punta Teno lighthouse under a starry sky, Santa Cruz de Tenerife, Spain 71479127 - Sphinx Observatory At Top Of Jungfraujoch and Snowcapped Mountain Range in a Sunny Winter Day in Canton Valais, Canton Bern in Switzerland.71479121 - Sphinx Observatory At Top Of Jungfraujoch in a Sunny Winter Day in Canton Bern in Switzerland.71479120 - Sphinx Observatory At Top Of Jungfraujoch and Swiss Flag in a Sunny Winter Day in Canton Bern in Switzerland.14625308 - A display of Northern Lights the day after the vernal equinox, on March 21, 2025, looking northeast with an ultra-wide-angle lens. This night the Kp was 5 to 6, with the Lights prominent at nightfall and active in the early evening but then fading away and receding to the north by about 10:30 pm MDT.14624950 - A fish-eye 360° view of a dim and weak display of Northern Lights on February 24, 2025, showing a green diffuse band to the south and a dim red curtain overhead with rays to the east. This red aurora was just visible to the eye as a grey streak. A bright meteor is at lower left below the Milky Way in the northwest. The Big Dipper is at centre almost overhead at the zenith.14624759 - The great aurora of May 31/June 1, 2025, here with a burst of red appearing for a brief time amid the curtains to the east as a substorm hit boosting the brightness and colours. On this night the Kp index peaked at Kp8, unusually high. However, to the eye the aurora still remained dimmer and colourless, except for moments like this when some reds did show up to the eye.14624751 - This is the Trifid Nebula, Messier 20, in Sagittarius, a combination of a magenta emission nebula and a blue reflection nebula. It is crossed by dark dust lanes that split it into a tri-segmented object, at least visually in the eyepiece.14624664 - A moonlit panorama at Dinosaur Provincial Park, Alberta, with a bright green aurora in the northeast behind the clouds moving in from the north, on June 2, 2025. Illumination is from the waxing quarter Moon amid clouds at left. The Kp Index was peaking at 7 this night, but even with the clouds, the aurora seemed to remain a bright but mostly diffuse glow.14624563 - The waxing 3.5-day-old crescent Moon, with Mars and Jupiter, all amid the stars of winter shine in the darkening twilight over the Bay of Fundy at Cape Enrage near Alma, New Brunswick. This night the Moon was close to the Pleiades star cluster which appears just below the Moon. The Moon had occulted the Pleiades a few hours earlier in the evening sky over Europe. The sky is dark enought to be star-filled but retains the deep blue of twilight and the horizon colours of sunset, in this late blue-hour scene.14624509 - This is a roughly 240º panorama recording a faint appearance of the STEVE (Strong Thermal Emission Velocity Enhancement) sub-auroral arc on the evening of May 28, 2025, with a Kp6 to 7 level aurora storm underway in the twilight. This STEVE was dim, and in a still bright sky, and was just visible to the eye as a grey band. The camera revealed the colours and structure.14624439 - A moonlit scene at Dinosaur Provincial Park, Alberta, with a bright green aurora in the northeast behind the clouds moving in from the north, on June 2, 2025. Illumination is from the waxing quarter Moon off frame to the left, and from sky twilight.14624436 - This captures a 180° panorama of the rich and colourful summer Milky Way over the iconic Sweetgrass Hills of Montana, specifically the West Butte, but as seen looking south from Alberta, from the Sunset Point viewpoint at Writing-on-Stone (Aisinai'pi) Provincial Park. From this latitude of 49º N the lower tail of Scorpius never rises above the horizon and the deep sky objects that are visible here appear low.14624435 - This is the small open star cluster NGC 6802 at the left (east) end of the asterism of stars called the Coathanger, or more officially Collinder 399, or Brocchi's Cluster, located in Vulpecula the Fox. However, the Coathanger is not a bound star cluster but is a chance alignment of stars. Nevertheless, it is a fine sight in binoculars.14624432 - A group of photographers is capturing a bright display of Northern Lights at the Churchill Northern Studies Centre, near Churchill, Manitoba. This was the first night of a five-night session for aurora tourists from the Road Scholar education travel company.14624429 - This captures the rich region of the summer Milky Way around the galactic centre as it was rising into position over the iconic Sweetgrass Hills of Montana, specifically the West Butte, but as seen looking south from Alberta, from the Sunset Point viewpoint at Writing-on-Stone (Aisinai'pi) Provincial Park. From this latitude of 49º N the lower tail of Scorpius never rises above the horizon and the deep sky objects that are visible here appear low. Though when I shot this Sagittarius was still rising and not at its highest yet. The timing was to get this field over the Hills.14623102 - This panorama scene captures the total eclipse of the Moon of March 13/14, 2025, with the red eclipsed Moon over Upper Waterton Lake in Waterton Lakes National Park, Alberta. This is looking south, with the cloud-obscured mountains in the distance in Glacier National Park in Montana.14622953 - This is a brilliant display of noctilucent clouds (NLCs) in the summer sky, June 29-30, 2025, taken from home in southern Alberta. These were unusually bright and obvious in the darkening twilight, across the northern sky. The glowing NLCs shine with an electric blue light, and as here exhibit repeating wave structures. They contrast with the dark tropospheric clouds seen in silhouette here against the twilight sky. NLCs appear to shine with their own light, though they are in fact reflecting sunlight coming over the pole.14622863 - This is the large and loose open star cluster IC 4665 in Ophiuchus, just above the yellow star Cebalrai, or Beta Ophuichi. It is sometimes called the Summer Beehive, but is also catalogued as Collinder 349 and Melotte 179. It is best viewed in binoculars or a telescope at very low power.14622809 - This wide view frames several of the southerly constellations of the northern hemisphere spring sky:14622536 - The Coma Berenices star cluster, aka Melotte 111, in deep twilight. The field of view is 3.8º by 2.5º.14621885 - This is the small and dim (for a Messier object) globular cluster Messier 56 in Lyra, set in a rich star field. It was discovered by Charles Messier in 1779.14621625 - A selfie of me observing in the backyard with the venerable (30-year-old) Astro-Physics Starfire 130mm (5-inch) f/6 refractor equipped with a Baader binocular viewer. I spent this night (May 6, 2025) observing a suite of showpiece double stars in the spring sky. Illumination is from a waxing gibbous Moon.14621562 - Here's a selfie of me looking through my telescope at the star cluster Messier 7 in the tail Scorpius, with the cluster very low on the southern horizon. The cluster Messier 6 is just above it. They appear just above the Sweetgrass Hills in Montana.14621336 - A selfie of me looking at the double star Alya, aka Theta Sepentis on a moonlit June night at home in my rural backyard in southern Alberta. The waxing gibbous Moon provides the illumination. The sky was somewhat smoky this night, a good one just for observing double stars.14620867 - This view frames some of the main constellations of the northern spring sky:14620791 - This is a widefield framing of the rich area in southern Gemini that contains the bright star cluster at centre, Messier 35, and its smaller companion cluster NGC 2158. The red nebula below it is NGC 2174, aka the Monkey Head Nebula, over the border in Orion. The crescent-shaped nebula left of the orange star Eta Gemnorum, or Propus, is IC 443, the Jellyfish Nebula, an ancient supernova remnant. The faint area of nebulosity left of the Jellyfish is IC 444.next page
