13899237 - The constellation of Andromeda, with Cassiopeia at upper left, and Pegasus at right, 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. The faint (in the moonlit sky) fuzzy patch of the Andromeda Galaxy, Messier 31, is visible at centre.13898535 - The constellation of Ursa Major, the Great Bear, and the asterism of the Big Dipper low in the north over Lake Edith in Jasper National Park, on a clear autumn night. Arcturus is at left setting over Pyramid Mountain.13898171 - The northern autumn constellations of Pegasus (partially seen at right), Andromeda (across the centre), Perseus (at lower left) and Cassiopeia (at upper left) rising 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. The Andromeda Galaxy, M31, is at centre. The star clusters NGC 752, M34 and the Double Cluster are at left, as well as the Perseus OB Association of stars. Some of the small star clusters in Cassiopeia are resolved as well.13898085 - Jupiter (bright at left in Pisces) and Saturn (dimmer at right in Capricornus) low in the southeast sky on a mid-September evening in 2022. Jupiter was then nearing its opposition, and a close one at that in 2022, appearing brighter than it usually does at opposition. Jupiter appears below the Square of Pegasus at upper left. This was from home in southern Alberta at latitude 51° N.13897910 - This is Comet NEOWISE (C/2020 F3) over the Horseshoe Canyon formation near Drumheller, Alberta on the night iof July 10-11, 2020, taken about 2 a.m. MDT with the comet just past lower culmination with it circumpolar at this time. Warm light from the rising waning gibbous Moon provides the illumination. The comet’s faint blue ion tail is just barely visible even in the moonlit sky and low altitude. The glow of summer perpetual twilight at latitude 51.5° N still colours the northern horizon despite this being close to the middle of the night.13897719 - The constellation of Andromeda with the famous Andromeda Galaxy (Messier 31) rising on an early summer night at Dinosaur Provincial Park, Alberta. This was June 30, 2022.13897557 - A bright green auroral arc with prominent red curtains, to the east in front of the winter stars rising. with bright Mars below centre and the Pleiades at top right. This was from home in Alberta on September 26, 2022.13999436 - An ice crystal halo around the waxing gibbous Moon set in the winter stars of a January night. The 22° halo is most obvious and with a reddish and sharper inner rim.,and a bluish and more diffuse outer edge. But a faint inner 8° halo is also visible,a rare halo sometimes called the Van Buijsen Halo (according to Lynch and Livingston in their book Color and Light in Nature; Minnaert also mentions it in his seminal book The Nature of Color and Light in the Open Air). It is not a lens flare as shots taken with the Moon well off to one side of the frame still show the inner halo centred on the Moo13999319 - This is the Perseid meteor shower over the badlands of Dinosaur Provincial Park,in the Red Deer River valley in Alberta,with the summer sky above filled with about two dozen meteors from the annual shower on August 12,2023. The meteors all appear to be streaking away from the radiant point in Perseus at left,below the "W" of Cassiopeia. The meteor trails are shortest near the radiant point,as at that location they are coming at us head on. The Andromeda Galaxy is near centre.13999304 - This is a framing of an array of emission nebulas in Cygnus: the bright North America Nebula (NGC 7000) at right,and to the right of it,the Pelican Nebula (IC 5067/8). Those bright nebulas are set amid a complex of fainter nebulosity,notably the Clamshell Nebula at left,as it has become known recently,and catalogued as Sharpless 2-119. At bottom right is the curving Cygnus Arc,aka IC 5068. The small star cluster NGC 7044,yellowed by interstellar dust,is below the Clamshell. The nebulas are marked by lots of structure and radial streaks,perhaps from magnetic fields.13998959 - The sparkling winter stars and constellations over the moonlit badlands of Dinosaur Provincial Park,Alberta on Feb. 4,2023. The waxing gibbous Moon is off frame at left providing the illumination on this very clear and mild night. Captured here in a vertical panorama from below the horizon to past the zenith.13998672 - 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 ar13998429 - This is a composite of the October 14,2023 annular solar eclipse at second contact. It illustrates the irregular edge of the Moon breaking up the rim of sunlight as the dark disk of the Moon became tangent to the inner edge of the Sun at second contact at the start of annularity. This is a blend of fifteen exposures taken over 20 seconds at second contact.13899816 - This is a framing of the rich complex of nebulosity in and around the constellation of Cygnus, in a blend of "white light" images and images shot through a deep red hydrogen-alpha filter that isolates the red emission line from the gas clouds, bringing them out in much more detail than is otherwise possible.13899635 - This is the central area of Cygnus and its bright Milky Way starcloud surrounded by red nebulosity. At left is the star Sadr (gamma Cygni) with the complex of nebulosity catalogued as IC 1318. At centre is the distinct Crescent Nebula, NGC 6888, a expanding nebula created by winds from a hot Wolf-Rayet star. At bottom left is the star cluster Messier 29, though looking a little lost in the rich starfields here. At top is the cluster IC 1311, looking more obvious than M29 but not observed visually and included in the NGC catalog. Odd. At far right are the large and loose star clusters NGC 6883 13899320 - This is the occultation of Mars by the Full Moon on December 7, 2022, in a composite showing the motion of Mars relative to the Moon. The motion here is from left to right. However, while this composite makes it look like Mars was doing the moving, it was really the Moon that was passing in front of Mars. But for this sequence I set the telescope mount to track the Moon at its rate of motion against the background stars and Mars, to keep the Moon more or less stationary on the frame while Mars and the background sky passed behind it.13898403 - The nearly Full Moon rising on March 18 near the date of the March equinox (March 20 this year) , so it rose nearly due east this night. This March Moon is also popularly called the Worm Moon.13898163 - This captures a panorama of the northern sky over the foreground landscape of Dinosaur Provincial Park, Alberta, with the waning Moon rising, and an arc of Northern Lights above the northern horizon. A Kp6 show was forecast for this night but nothing spectacular materialized -- we had just a quiescent arc across the north.13897773 - NGC 281, aka the Pacman Nebula, in Cassiopeia, near the bright star Schedir (or Shedar), at right, and below Achird at top.13999530 - The stars of the northern sky over Castle Mountain in Banff National Park,Alberta. This was June 6,2023 on a very clear night,but bright with blue summer twilight at this latitude of 51° N in June. The W of Cassiopeia and the Milky Way are at right. Polaris is at top.13999053 - This is a framing of the main area of central Auriga filled with an array of Messier star clusters and faint IC emission nebulas.13998285 - An ice crystal halo around the waxing gibbous Moon set in the winter stars of a January night. The 22° halo is most obvious and with a reddish and sharply defined inner rim and a bluish and more diffuse outer edge. But a faint 8° halo is also visible,a rare halo sometimes called the Van Buijsen Halo (according to Lynch and Livingston in their book Color and Light in Nature; Minnaert also mentions it in his seminal book The Nature of Color and Light in the Open Air). It is not a lens flare as shots taken with the Moon well off to one side of the frame still show the inner halo centred on the Mo13899645 - Jupiter (brightest), Saturn (to the left), and the Milky Way over the Saskatchewan River and the area of Howse Pass, on July 26, 2020. Mount Cephren is at left; the scene is framed to include Cephren. The nebulas and star clouds of the galactic centre area at right show up well on this very clear night. The bright Small Sagittarius Starcloud, aka M24, is most obvious, flanked by the star clusters M23 and M25 to the side, and the nebulas M17 and M16 above, and M8 and M20 below. The fuzzy globular cluster M22 is to the left of the large Lagoon Nebula, M8. Green airglow tints the sky.13899372 - A selfie of me observing with the 20cm Sky-Watcher Dobsonian telescope on a June night in the backyard. Shot for a book illustration of accessories and observing. The sky is blue from solstice twilight as this was June 18, 2020. The galactic core is at centre; Jupiter is rising at left.13899323 - This is the complex of nebulosity that has become known as the Cosmic Question Mark, a good name as its official designations are confusing.13898806 - Comet NEOWISE (C/2020 F3) over some of the eroded hoodoo formations at Dinosaur Provincial Park, Alberta, July 14-15, 2020. Twilight colours the sky. In this case the foreground is mildly light painted with a warm LED light. This was from the Trail of the Fossil Hunters site.13898682 - The autumn constellations of Perseus and Cassiopeia above, with bright Capella in Auriga and the Pleiades star cluster in Taurus, at bottom, rising in the northeast over Lake Edith in Jasper National Park, on a clear autumn night. The Double Cluster is at centre, above the larger group of stars around Mirfak called the Perseus Association.13897976 - Comet NEOWISE (C/2020 F3) over a ripening canola field near home in southern Alberta, on the night of July 15-16, 2020. Light pollution from a nearby gas plant reflecting off low clouds and a rain shower adds the yellow at right.13897908 - The Moon in mid-total eclipse, on January 20, 2019, with it shining beside the Beehive star cluster, Messier 44, in Cancer. This was the unique sight at this eclipse as it can happen only during total lunar eclipses that occur in late January. There was one on January 31, 2018 but the next will not be until 2037.13897791 - This is the line-up of planets across the southwestern sky on December 6, 2021, consisting of (L to R): Jupiter, Saturn and Venus, with the 2.5-day-old waxing crescent Moon in conjunction below Venus. The Moon had eclipsed the Sun two days before on December 4, when it was on the ecliptic. Two days later it was below the ecliptic line. Jupiter and Saturn are in Capricornus, with its stars all visible here in the evening twilight. The three planets are nicely equally spaced. Such an array makes the ecliptic line visible.13897703 - A line-up across the southwestern sky on December 5, 2021, consisting of (L to R): Jupiter, Saturn and Venus (brightest), with Jupiter and Saturn in Capricornus, with its stars all visible here though dim in the twilight. The three planets are nicely equally spaced here. Such an array makes the ecliptic line visible.13897654 - This captures the vertical sweep of the summer Milky Way over the foreground landscape of Dinosaur Provincial Park, Alberta. The image serves as a good illustration of the richness of objects, dark dust lanes and bright starfields along the Milky Way, from Sagittarius low in the south at bottom, to Cygnus at top. In between are Aquila and Scutum, with part of Ophiuchus at right. This was from latitude 50.5° North, where Sagittarius and the galactic centre are low in sky. The Summer Triangle stars of Deneb, Vega and Altair are at top.13884758 - Sika deer (Cervus nippon) on the island of Miyajima, also known as Itsukushima. More than a thousand of the deer live on the island, wandering in search of food and attracting attention of tourists; Hiroshima, Japan70188614 - Jumble of houses built into a cliff in Positano, Italy along the Amalfi Coast.70438561 - Close up of liquid in pipette.
