The formation of dark lanes called the Dark Emu in Australian aboriginal sky lore, seen here in its entirety with it overhead in the April pre-dawn sky. The head is at right in Crux, as the Coal Sack, the body is around the Galactic Centre, the tail is at left in Scutum. Some airglow discolours the sky. This is a stack of 5 x 2.5-minute exposures with the 14mm Rokinon lens at f/2.8 and filter-modified Canon 5D MkII at ISO 1600. On the iOptron Sky-Tracker. From Tibuc Gardens Cottage near Coonabarabran, NSW, Australia, Aoril 28, 2017.
The “Dark Horse” region of dark nebulosity near the galactic centre in Scorpius and Ophiuchus, also known as the Pipe Nebula. The small squiggly Snake Nebula is above centre. This is a single frame, made of a stack of 4 x 3-minute exposures with the 135mm telephoto lens at f/2.8 and filter-modified Canon 5D MkII at ISO 1600. Taken from Tibuc Cottage, Australia, April 13, 2016.
The region around the Pipe Nebula (B78), the main part of the naked-eye formation of dark nebulas called the Dark Horse. In photos it breaks up into patches of dark nebulosity, including the tiny Snake Nebula (B72) at centre in Ophiuchus. I shot this the morning of May 5, 2014 from the Four Bar Cottages near the Arizona Sky Village near Portal, Arizona. This is a stack of 5 x 3 minute exposures with the 135mm telephoto lens at f/2.8 and filter modified Canon 5D Mark II at ISO 1600. It is one segment of a larger multi-panel mosaic.
