Description

a closer look at the CrA nebula complex reveals an amazing mixture of dust plumes and reflection nebulae, caused by the light of bright young stars shedding on the dust. The globular NGC6723 lies in the far distant, just over the border to Sagittarius.

A full field with 300mm and fullframe EIS6d is provided, an annotated version, and a crop on the central portion with its intricate detail
