oc Dunlop 224
The open cluster Dunlop 224 = Harvard 6 is about 45' north of alpa in Musca.
Dunlop found it in 1826 and described it as " An exceedingly faint nebula, extended in the direction of the meridian, about 4' or 5' in length, with a line or group of very small stars in it."
He found about 20 non NGC/non IC open clusters. They were not included in the NGC because John Herschel failed to see them.
The attached wikisky.org image shows beta Mus top left, H6 and alpa Mus lower right.
