The Pointer Stars (Alpha and Beta Centauri, at left) pointing to the stars of the Southern Cross, Crux, at right. The Coal Sack, obvious as a dark patch in the Milky Way to the naked eye, here looks less obvious as it breaks up into streaks and bands of dark dust to the left of the Cross. This is a stack of 5 x 2.5-minute exposures at f/2 with the 85mm Rokinon manual lens, and filter-modified Canon 5D MkII at ISO 2000. Plus one exposure through a Kenko Softon A filter layered in to add the star glows.
