About C105

Description

NGC 4833 is a globular cluster in Musca, about 21,200 light-years away. It spans about 14 arcminutes and shines at magnitude 7.4. The cluster lies behind significant foreground dust, which reddens and dims it somewhat.

Observing Tips

Visible as a moderately bright, round glow in a 4-inch telescope. An 8-inch scope resolves the outer stars. The foreground dust gives the cluster a slightly reddened appearance. Best from southern latitudes in autumn and winter.

History

Discovered by Nicolas Louis de Lacaille in 1751 from South Africa. It is one of the more obscured globular clusters in this part of the sky due to intervening Milky Way dust.

Fun Facts

NGC 4833 is one of the more metal-poor globular clusters in the Milky Way, suggesting it is among the oldest. Its position behind moderate interstellar extinction has historically made precise measurements challenging.
