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. This is a stack of 10 x 7 minute exposures at f/2.8 with the Canon 135mm L series lens and filter-modified Canon 5D MkII at ISO 640. One exposure had soft stars from high altitude haze which added the glows around stars naturally. Shot from Coonabarabran, Australia, December 14/15, 2012. This is a better version than #1 shot the night before under some haze and cloud.
The Milky Way of a late May night, in 2017, with Saturn amid the Milky Way at right, near the dark lanes of the Dark Horse. SHot from home in Alberta (latitude 51° N) as part of a time-lapse sequence testing the Star Adventurer Mini tracker and motion controller. Messier 6 star cluster, one of the most southerly Messier objects is just above the trees at right. The Small Sagittarius Star Cloud (aka M24) and Scutum Star Cloud (above) are the bright patches in the Milky Way. The Lagoon Nebula, M8, is the pink patch below M24. This is a single 22-second exposure at f/2.2 and ISO 3200 with the Canon 6D and 35mm lens, one frame from a motion-control panning sequence.
A vertical sweep with a 15mm ultrawide lens from the horizon to past the zenith, taking in a large part of the northern winter Milky Way. Orion is right of centre; Canis Major and Sirius (the night sky’s brightest star) are below and to the left of orion. The second brightest star in the night sky, Canopus, is just above the southern horizon at right. It just clears the horizon at 32° North latitude. Jupiter is the bright object at left, just left of the Beehive star cluster, M44, in Cancer. The Pleiades star cluster, M45, is at upper right in Taurus. The larger Hyades star cluster is below it. The small light dome on the horizon at left is from Las Cruces and El Paso. Otherwrise the site was perfectly dark and free of any man-made light sources. I shot this March 10, 2015 from the summit of the Trail of the Mountain Spirits Highway, Hwy 15, in the Gila Wilderness of southern New Mexico, at an altitude of 7900 feet. I shot this in the last of the deepening twilight before the sky was completely black. Some twilight blue remains. The bright glow at upper right is from the top of the Zodiacal Light cone in the western sky - a natural form of “light pollution.” The image is a stack of 4 x 3-minute tracked exposures, with the 15mm lens at f/3.5 and Canon 5D MkII at ISO 1600. The camera was on the Star Adventurer tracker.
