13898158 - A fish-eye lens / all-sky view of the STEVE aurora arc across the sky and in clouds on May 6, 2018, from home in southern Alberta, with a diffuse aurora to the north casting streaks of purple up the sky, and a green glow along the horizon. This night the aurora was very active to the north and east with a terrific display in Churchill, Manitoba about an hour before this, matching the usual STEVE characteristic of him appearing as a major storm subsides.13897757 - A horizon-to-zenith panorama of the winter consellations on a March evening as they set into the southwest. Orion is at bottom centre, with his Belt pointing down to Canis Major and up to Taurus. Gemini and Auriga are at top, in this case near the zenith overhead. The bright star clusters, M44, the Beehive, (at left) and M45, the Pleiades, (at right) flank the Milky Way. M45 is embedded in the Zodiacal Light. The star clusters M35 in Gemini and M41 in Canis Major are also visible as diffuse spots, as are several other star clusters. A couple of satellite trails are visible.13998456 - A panorama of the extensive aurora of Oct 20/21,2023,from home in southern Alberta. The aurora coloured much of the sky,but was most prominent as a larrge diffuse arc across the north,with a more active structured arc low in the north. This was at local midnight,MDT.13899923 - The spectacular field of Messier 8 and 20 emission and reflection nebulas in Sagittarius, with M8, aka the Lagoon Nebula below, and M20, the Trifid Nebula, above, all set in the rich starfields of the Milky Way. The diffuse nebula left of M8 is NGC 6559. Two globular clusters, NGC 6544 and NGC 6553, sit below and to the left (east) of M8. The Messier open cluster, M21, sits above M20.13899715 - One of a short series of images showing the development of an aurora display from a classic arc into a more complex pattern of concentric arcs and with loops and swirls. This was Feb 5, 2019 from the Churchill Northern Studies Centre. The outburst lasted only 5 minutes or so and might have been due to the Bz interplanetary field turning south briefly. After this series, the display faded and fractured into faint arcs and a diffuse glow across the sky.13999418 - A framing of a field in southwestern Gemini rich in star clusters and nebulas. At top right is the rich star cluster Messier 35 and its small more distant companion cluster NGC 2158. At bottom right is the emission nebula NGC 2174 that is over the border in northern Orion. Above centre is the supernova remnant IC 443 arcing to the east of the orange star Propus or Eta Geminorum. The large diffuse nebula at left is IC 444 above the orange star Tejat Posterior or Mu Geminorum. The large,loose cluster Collinder 89 is embedded in IC 444. That region also has some blue reflection nebulosity,as does13999628 - The aptly-named Coathanger Cluster,a more properly an asterism of stars in Vulpecula. A true star cluster,NGC 6802,lies at the left end of the coathanger arm. The field contains diffuse blue reflection nebulosity which appears to not have a catalogue number. The small round emission nebula at bottom is Sharpless 2-82. A very small round red nebula above the right end of the Coathanger is Sh2-83.13999436 - 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 Moo13899461 - This is the rich region of clusters and nebulosity in the constellation of Gemini, with the Jellyfish Nebula, IC 443 at bottom near the orange star eta Geminorum. IC 443 is a supernova remnant. The larger region of fainter, diffuse nebulosity at left is IC 444. The loose star cluster embedded in it, with the blue star 12 Gem, is Collinder 89. At top right is the bright showpiece open star cluster Messier 35 with its smaller, more distant companion cluster NGC 2158 at lower right from M35.13998285 - 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 Mo13898300 - A 150° panorama of an arc of diffuse aurora to the northeast, and above the glow of solstice twilight to the north at centre, while the urban sky glow from Calgary lights the sky at left to the west, as well as an odd band of cloud that persisted all evening across the north.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.13774440 - Diffuse Light Brings Unique Color To The Surf On The Oregon Coast; Newport, Oregon, United States Of America70235744 - Sun Beams diffuse Ocean, Micronesia, Palau70580676 - Sonnenstrahlen durchdringen Meeresoberfläche, Mikronesien, Palau, Sun Beams diffuse Ocean, sea, Micronesia, Palau70391088 - A small excursion boat floats down the Hozu River valley amidst rental rowboats and a palette of autumn hues under diffuse light in the northwest Arashiyama district of Kyoto, Japan.
