1350-27 - The nebulas of Orion in the Belt and Sword of Orion area. Including M42, Orion Nebula 9below centre), Barnard's Loop (at left), M78 (small reflection nebula above centre), Horsehead Nebula (centre) and NGC 2024 (above Horsehead). There is faint reflection nebulosity at right -- the frame does not extend right far enough to show the Witchhead Nebula near Rigel.
1350-116 - 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�8 N still colours the northern horizon despite this being close to the middle of the night.
1350-178 - The asterism of the False Cross in Vela and Carina, at left, with Gamma Velorum, a bright blue supergiant star, at right. In between are faint arcs of nebulosity in the Gum Nebula. To the left of Gamma Velorum is the open star clister NGC 2547. Below the bottom star of the False Cross, Epsilon Carinae or Avior, is the large naked-eye star cluster NGC 2516. To the right of the right star of the False Cross, Delta Velorum, is the loose open cluster IC 2391.
1350-39 - Astronomer Vance Petriew at the eyepiece of his 20-inch Dobsonian reflector telescope, at the 2012 Saskatchewan Summer Star Party in Cypress Hills, SK. This is a single 20 second exposure with the Canon 5DMkII at ISO 4000, and 24mm Canon L-series lens at f/2. A faint aurora adds the horizon colours. The photo was taken on the occasion of the second return of Comet Petriew 185/P since its discovery 11 years earlier in 2001 at this very same location.
1350-115 - 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.
1350-79 - The Belt and Sword region of Orion, with the Orion Nebula, Messiesr 42 and 43, at bottom. Below the left star of the Belt, Alnitak, is the famous Horsehead Nebula, while above it is NGC 2024, aka the Flame Nebula. At very top left is Messier 78, while part of Barnard's Loop arc across the field at left. The field is filled with other faint red emission and blue reflection nebulas. The large loose open cluster Collinder 70 surrounds the middle star of the Belt, Alnilam.
1350-16 - Comet Holmes, 17P, taken Nov 1, 2007 on excellent night. Taken with A&M 105mm apo refractor at f/5 with Borg 0.85x compressor/field flattener on SkyWatcher HEQ5 mount. Canon 20Da camera at ISO400. Composite of 4 min, 2min, 1min, 30sec, 15sec, and 7 sec exposures, each exposure being a stack of 3 to 4 identical exposures. Registered and stacked in Photoshop (HDR mode did not produce usable result, so manually composited with sucessively smaller masks to reveal short exposure content around nucleus. Contrast exaggerated with Curves to bring out very faint tail structure. North up, so tail to the S and SW.Nucleus is dot at upper left of inner coma, other star in inner coma at right is a field star
1337-21 - An Acacia Koa tree reaches out over the Waimea Canyon as a faint sunset rainbow stretches over Waipo'o Falls, Kauai, Hawaii, United States of America, Pacific
1116-48916 - The faint glow of Aurora Borealis in the night sky illuminates the sparse cloud over Moose Pass, Kenai Peninsula, South-central Alaska, Moose Pass, Alaska, United States of America
