Omega Centauri, NGC 5139
Located in the constellation Centaurus, Omega Centauri is the largest globular cluster in our Milky Way galaxy.
This is the second target visible only in the southern hemisphere I have imaged since moving to South Africa. Omega Centauri is especially impressive to me coming from the USA and being used to M13, the Hercules globular cluster, which used to seem big.
