Crux, Southern Cross, Mosaic (77mm 5DII).jpg
A mosaic of the Southern Cross, Crux.
Acrux, Alpha Cruxis, is the star at bottom and Becrux, Beta Cruxis, is the star at left, with the Jewel Box Cluster, NGC 4755, just to the left of Becrux. Reddish Gacrux is at top and Delta Cruxis is at right. The star cluster NGC 4349 is above Alpha Cruxis. The bright red nebula in the dark Coal Sack is Gum 46. The rich cluster to the right of Becrux is Harvard 7. The dark nebulosity at lower left is the Coal Sack. The small cluster embedded in the Coal Sack to the left of Acrux is NGC 4609, what I call the Coal Dust Cluster. Slight haze or high cloud added the natural star glows here.
Technical:
This is a moasic of 3 panels, each a stack of 4 x 4-minute exposures with the Borg 77mm f/4 astrograph and filter-modified Canon 5D MkII at ISO 1600. No filter was employed here. Stacked and stitched in Photoshop. Shot April 5, 2016 from Tibuc Cottage, Coonabarabran, NSW, Australia. Reprocessed in 2025.
