In the Coalsack, image published here https://astrob.in/353867/B/ it is mentioned a tiny cluster of stars NGC 4609. It is magnified by my Tamron 1200 mm.
It was discovered by James Dunlop in 1826 and later included in the NGC by John Herschel.
The biggest star on the image is HD 110432 and probably part of NGC 4609.
Slightly below, on the left, there is a small open cluster called Hogg 15. It has the particularity of containing a Wolf-Rayet star (WR 47).
These two clusters would apparently lie behind the Coalsack.
I made the stars twinkle...
