Description

83min of integral LRGB exposure of the FeSt1-203 high density area in the corner of the Coalsack nebula near Acrux (which floods the left bottom corner with parasitic (yet artistic) light). Captured using Telescope #3 (ASA-N D = 0.5m f/3.8, FLI ProLine 16803) systems of ChileScope observatory (remotely), over 3 imaging sessions carried out on Jan 11, 25, 26, 2021. Many grades of darkness in this area, with nice attenuation on the edges.

This area is identified as "AV-Large" area in Fig. 1 on page 25 in [1].
