A mosaic of the region in the tail of Scorpius from the False Comet Cluster (NGC 6231), at left in the starclouds in the tail of Scorpius, to what I call the Dark River Cluster, NGC 6214, at right, an open star cluster contrasting with lanes of dark nebulosity. This is a two-panel mosaic, each panel a 4 x 6-minute stack with the Borg 77mm astrograph at f/4 and filter-modified Canon 5D MkII at ISO 1600. Taken from Tibuc Cottage, Australia, April 11, 2016. Stacked and stitched in Photoshop CC 2015.
