13999415 - Comet C/2022 E3 (ZTF) passing Mars in the constellation of Taurus on the night of Feb 10,2023. Mars appears to be at the tip of a dark lane of interstellar dust in the Taurus Dark Clouds. The comet is showing its whitish dust tail and blue ion tail,as well as its cyan coma from diatomic carbon emission. The star cluster at left is NGC 1746.13999315 - Comet Nishimura (C/2023 P1),at left,captured at dawn on September 7,2023 with the sky beginning to brighten with morning twilight colours. Plus the last quarter Moon was lighting the sky and landscape with moonlight. The comet appears with Venus,at right,beginning its morning sky appearance for 2023/24. In addition,the star cluster Messier 44,the Beehive,is at top right. The smaller Messier 67 star cluster is just above Venus.13998840 - Comet Nishimura (C/2023 P1) captured about 25 minutes after rising in the pre-dawn sky on September 10,2023 with the sky bright with morning twilight colours. The comet was only about 4º above the horizon at this time. This was about 5:25 am MDT.13998596 - The infamous "Green" Comet C/2022 E3 (ZTF) passing by reddish Mars with both in the constellation of Taurus on the night of Feb 11,2023. The comet was 2° south of Mars this night. Mars was embedded in some of the dark obscuring dust clouds in Taurus,creating the dark patchy appearance to the background sky. The comet's coma glows cyan due to emission from diatomic carbon molecules,a common trait of comets. The dust tail and faint ion tail are just visible.13898668 - Comet Hale-Bopp13999412 - Comet C/2022 E3 (ZTF) in the constellation of Taurus on the night of Feb 10,2023. The comet is the cyan-coloured glow above bright orange Mars at upper left.13999163 - Comet C/2022 E3 (ZTF) in the constellation of Taurus on the night of Feb 10,2023. The comet is the cyan-coloured glow above bright orange Mars.13999146 - Comet Nishimura (C/2023 P1) captured at dawn on September 7,2023 with the sky brightening with morning twilight colours. The comet was set amid the stars of the Sickle asterism of Leo the Lion,just rising in the east. The comet sports a faint blue ion tail,with the comet seemingly pointed toward the sunrise point; it was moving down and closer to the Sun at this time.13998741 - A portrait of green Comet C/2022 E3 (ZTF) in Taurus beside Aldebaran and the Hyades on February 14,2023. The star cluster NGC 1647 is at upper left.13998648 - A portrait of green Comet C/2022 E3 (ZTF) in Taurus beside Aldebaran and the Hyades on February 14,2023,with Mars at upper left,and the Pleiades at upper right. This frames some of the other NGC star clusters in Taurus.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.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.13899261 - Comet Leonard (C/2021 A1) on the morning of December 10, 2021, with a 200mm telephoto lens for a field of view of 10° x 6.8°. The tail appears to be about 3.5° long here. Taken about 6:30 am MST with the comet as high as it would be, though the sky is already beginning to brighten with the blue of dawn twilight. The distinctive cyan tint of a comet's coma is prominent.13899090 - Comet PANSTARRS C/2011 L4 and the thin waxing Moon, March 12, 2013, over the Chiricahua Mountains, in Arizona, but seen from New Mexico, from a site on Highway 80 north of the Painted Pony Resort. A 2s exposure at f/2.8 and ISO 640 with the Canon 60Da and 135mm telephoto + 1.4x Extender.13898898 - Comet NEOWISE (C/2020 F3) over some of the eroded hoodoo formations at Dinosaur Provincial Park, Alberta, July 14-15, 2020. A faint aurora is at right. The foreground is lit by starlight only; there was no light painting employed here.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.13898641 - Comet Hale-Bopp13898314 - Comet NEOWISE (C/2020 F3) in a telephoto lens close-up on July 19, 2020, showing the straight blue ion tail and the curving whitish-yellow dust tail. Even the ion tail was visible in binoculars and traceable out for 12° or so, or two binocular fields. A bit of cyan colour is visible around the head of the comet. The ninth magnitude galaxy NGC 2841 is visible to the right of the comet.13898245 - This is Comet Wirtanen 46P in Taurus on December 14/15, 2018 accompanied by a meteor, caught by chance of course. The meteor has left a yellowish “smoke” cloud.13898154 - Comet Leonard (C/2021 A1) on the morning of December 10, 2021, with a 135mm telephoto lens for a field of view of 10° x 15°. The tail appears to be about 4° long here. Taken about 5:45 am MST. The distinctive cyan tint of a comet's coma is prominent. The comet was in Serpens at the time.13998387 - Comet C/2022 E3 (ZTF) on the night of January 22/23,2023 when it was in Draco,with it near the reddish star Edasich (aka Iota Draconis) at top,and the edge-on galaxy NGC 5907 below the comet. To the right of that galaxy is NGC 5866,aka M102. The dust tail of the comet was showing a strong anti-tail spike ahead of the comet's greenish coma,as this was two days before we crossed the plane of the comet's orbit when we would see its dust tail "edge-on." The coma of the comet is strongly cyan or green from glowing diatomic carbon molecules,common for comets. There was little sign of the blue ion ta13998259 - Comet C/2022 E3 (ZTF) in the constellation of Auriga on the night of Feb 8,2023. The comet is the small cyan-coloured glow above centre. It was technically in Auriga but heading south into Taurus and in front of the Taurus Dark Clouds here at centre. Mars is the bright orange object right of centre.13900057 - A close-up of Comet NEOWISE (C/2020 F3) on the night of July 14/15, 2020 with a 135mm telephoto lens, and cropped in somewhat. But the field is about 10° high and the white dust and blue ion tails extend across the frame and beyond it. Some of the banding structure in the dust tail is visible.13898737 - A selfie observing Comet NEOWISE (C/2020 F3) with binoculars on the dark moonless night of July 14/15, 2020 from Dinosaur Provincial Park, Alberta. A faint aurora colours the sky green and magenta. The faint blue ion tail of the comet is visible in addition to its brighter dust tail. The ground is illuminated by starlight and aurora light only.13897961 - Comet NEOWISE (C/2020 F3) with the Northern Lights over the Waterton River at Waterton Lakes National Park, Alberta, on July 13-14, 2020. This was from the Maskinonge picnic area.13899854 - 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 adds the yellow at right.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.13897728 - Comet NEOWISE (C/2020 F3) over the still waters this night of Crawling Lake in southern Alberta. The Big Dipper is at top. Even in this short exposure, the two tails — dust and ion — are visible. This was July 20, 2020. The blue ion tail is extending up into the Bowl of the Big Dipper, for some 20° in length. Very impressive!13897417 - Comet Hartley 2 near the Pacman Nebula, NGC 281, in Cassiopeia. Stack of 4 x 6 minute exposures at ISO 1600 with Canon 5D MkII on A&M 105mm apo refractor at f/4.8 with Borg reducer/flattener. Bright star is Alpha Cas, Schedar. Autoguided with Celestron NexGuide autoguider. However, image of comet core is from only one exposure to minimize trailing from this fast-moving comet.13898763 - Comet NEOWISE (C/2020 F3) reflected in the still waters this night of Crawling Lake in southern Alberta. A dim aurora at right colours the sky magenta. Lingering twilight colours the sky blue. A meteor or more likely a flaring satellite appears at right and is also reflected in the water. Even in this short exposure, the two tails — dust and ion — are visible. This was July 20, 2020.13897653 - Comet Hale-Bopp with Owl13999047 - Comet 2022 E3 (ZTF) at top,as the green fuzzy star above the semi-circle of stars marking the constellation of Corona Borealis,the Northern Crown. The comet was approaching the Sun and Earth at this time (January 3,2023) and was brightening,but even here was visible in binoculars and sporting a short dust tail and cyan-colored coma. ZTF = Zwicky Transient Facility,the telescope used to discover the comet in early 2022.13999038 - Comet Nishimura (C/2023 P1),at left,captured about 30 minutes after rising in the pre-dawn sky on September 10,2023 with the sky bright with morning twilight colours. The comet was only about 4.5º above the horizon at this time.13998517 - Comet Nishimura (C/2023 P1),at left,captured just after rising in the pre-dawn sky on September 10,2023 with the sky beginning to brighten with morning twilight colours. The comet was only about 2º above the horizon at this time.13898894 - Comet Lovejoy (C/2104 Q2) on the night of Dec. 27/28, 2014, as it was approaching the globular cluster M79 at upper right, in Lepus. This is a stack of 5 x 3 minute exposures at ISO 2500 with the Canon 5D MkII and TMB 92mm refractor at f/4.4. Taken from near Silver City, New Mexico.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.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.13897613 - This is Comet NEOWISE (C/2020 F3) over Deadhorse Lake near Hussar in southern Alberta, taken just after midnight on July 10-11, 2020 during its evening appearance. The comet shines just above low noctilucent clouds. The slight wind ruffled the waters enough to prevent the clean reflection I was after.13897554 - Comet Wirtanen (aka 46P) as it appeared in my sky on November 28, 2018 with it still only 17° above my southern horizon, so partly in haze. The comet was obvious in big 10x70mm binoculars as a large diffuse glow. Wirtanen was moving north and had just entered my western Canadian sky the week I took this.71353420 - Comet NEOWISE is photographed in front of a bony old tree on a foggy meadow, Germany, Brandenburg, Spreewald70205324 - McNaught comet flying over the night sky, Patagonia, Argentina, South America70043383 - Aurora borealis with Hale Bopp comet star traces, Alaska, USA71097317 - a comet in the sky.70167386 - Comet Hale-Bopp in the constellation Perseus above Mt.

This area was directly overhead when I took this at about 4:30 am local time on April 6, 2014 from near Coonabarabran, Australia. The head of Scorpius is at top his tail at bottom though you could turn this image any direction and it would be correct as seen in the sky at this latitude, depending on the time of night. But in portrait mode like this north is at top. Along the Milky Way are numerous nebulas, including the False Comet area, the Cat's Paw area, and the colourful nebulas around Antares at top. The dark 13899040 - A scene at the public "Parks 'n Stars" stargazing night, March 15, 2015, at the City of Rocks State Park, New Mexico, and at their Gene and Elizabeth Simons Observatory in the Orion group campground. Here observers are aiming their laser pointers at the position of Comet Lovejoy in Cassiopeia, just visible at top left. Observers are using the big binoculars to view the comet.13898926 - A single image of bright noctilucent clouds in the dawn sky over a prairie pond near home in southern Alberta on July 7, 2020, with Venus bright as a “morning star” at right above Aldebaran. Comet NEOWISE was in the scene but hidden behind dark weather clouds here.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.13898092 - A 360° fish-eye panorama of the evening sky, January 16, 2015, showing the Zodiacal Light rising out of the western sky and last vestiges of twilight, and the Milky Way across the sky in the east. Comet Lovejoy (C/2-14 Q2) near the Pleiades just left of centre at the top of the pyramid of light from the Zodiacal Light. A meteor appears below centre. This is a stitch of 8 segments, each taken with the 15mm lens and Canon 6D in portrait orientation, for 1 minute at ISO 3200 and f/2.8. Stitched with PTGui.13900090 - Venus in the evening twilight on December 17, 2021, about 2 weeks after its point of greatest brilliancy. This was shot in hope of also catching Comet Leonard, but it showed up as only a dim smudge hard to distinguish from the background sky, and is behind thin cloud here. Shot from near home in southern Alberta. Foreground illumination is from the gibbous Moon to the northeast opposite this scene which looks southwest.13899523 - The northern stars turn around Polaris and the North Celestial Pole in a composite of 400 images taken for a time-lapse and stacked here using Advanced Stacker Actions in Photoshop to create the comet trails effect - Using Comets 90% mode. Taken at the Table Mountain Star Party July 26, 2014 using the 14mm Rokinon lens and Canon 6D. Each exposure was 45 seconds at ISO 200.13998276 - This is the odd sight of an arc of light across the sky created by the high-altitude fuel dump from an orbiting rocket. It looks like a huge comet or an odd auroral arc.13899867 - A telescopic closeup of Comet Lovejoy (C/2014 Q2) on January 17, 2015, showing structure in the ion gas tail, in the form of streamers and discontinuities in the tail.13899076 - Comet Lovejoy, C/2014 Q2 amid the clusters, nebulas and dark dust clouds of Taurus and Perseus, on Friday, January 16, 2016. Its long blue ion tail stretches back at least 15°, almost to the open cluster NGC 1647 on Taurus at the left edge. At centre is the Pleiades star cluster, M45; at top right is the red California Nebula, NGC 1499, in Perseus, while the field is filled with the dark dusty lanes of the Taurus Dark Clouds. At left is the red giant star Aldebaran amid the V-shaped Hyades star cluster.13898512 - A telescopic closeup of Comet Lovejoy (C/2014 Q2) on January 19, 2015. I shot this from near Silver City, New Mexico, using a TMB 92mm apo refractor at f/4.4 and using a Canon 6D at ISO 1600 for a stack of 4 x 5 minute exposures. The ion tail is primarily from a single exposure to minimize blurring from the comet’s motion relative to the stars. The rest of the image is from the stacked combination to minimize noise.13846970 - Comet Glass Star sculpture made for Christmas 2007 by Master glass maker Simone Cenedese, displayed at Campo Santo Stefano, Murano, Venice, Italy13900199 - The False Comet Cluster area of southern Scorpius, which includes the open cluster NGC 6231 and emission nebula IC 4628, and open cluster NGC 6242 at top. This is a superb binocular field.13899193 - Tail of Scorpius with False Comet area (NGC 6231 and IC 4628) and Ara )with NGC 6188 nebulosity), taken from Atacama Lodge, Chile, March 2010, with Canon 5D MkII (modified) and Canon L-series 135mm lens at f/2.8 for stack of 5 x 4 minute exposures at ISO 800.
