LEAPING EMU IN THE FAR-SOUTHERN SK Y Howard L. Ritter Jr. This stretch of the Milky Way starts at the tail of Scorpius (far left) and glides up through Crux and the Coal Sack (center) to the Carina Nebula and beyond. Aboriginal Australians imagined this region's dark nebulae as an emu, with the Coal Sack as its head. The Magellanic Clouds are at lower right. The camera sat on a picnic table for this untracked celestial snapshot. DETAILS: Nikon D810A DSLR camera at ISO 3200 with a 14-to-24-mm lens set to 14 mm. Exposure: 30 seconds. sskkyyaannddtteelleessccoo p p e . c o m * O C T O B E R 2 0 17 73http://www.skyandtelescope.com
