    Description

    Corona Australis, the southern crown, is located next to the galactic bulge, and harbours a complex of dust plumes and reflection nebulae. Visually the dust looks like a shadow cast on the background stars, but on the photo it can be displayed with depth and detail. To the right the condensing mass of bulge stars intensify ever more, forming a counterpoint rarely seen in an astrophoto.

    A full field with Samyang 135mm at open f/2 and Eos6d is shown, and an annotated version. To take a closer look please move on to the next picture entry, taken with 300mm.
