Description

50min integral LRGB exposure for the Coalsack dark nebula region captured remotely using Telescope #4 (Nikkor 200mm f/2, FLI Microline 16200) system of ChileScope observatory, also known as VST - a Very Small Telescope)) The complexity of this region is astounding, the small and dense molecular clouds are all over the place, and the Acrux shining on its boundary only adds for the contrast of the scene.

I also found this reference paper of much use while targeting the substructures of this region for narrower views:
