Background
NGC 4833 is a bright globular cluster 21,000 light-years away in Musca, embedded in a relatively rich Milky Way starfield. About 12 billion years old, it sits close enough to δ Muscae to make a convenient star-hop target.
My Observing Notes
25-cm (Meade 10-inch LX200, The Coffee Grinder): Easy to find without Go-To: δ Muscae in the viewfinder shows the globular as a faint fuzz in the 9×50 finder. In the eyepiece, relatively bright with chains of brighter stars resolved.(Thursday, April 2025)
