Discovered by Nicholas Louis de Lacaille in 1752.
The considerable southern open cluster NGC 3766 was discovered by Nicholas Louis de Lacaille on March 5, 1752 from South Africa.
The red nebulosity you can see starting to appear on the right of NGC 3766 is from the nearby emission nebula Lambda Centauri (IC 2948).
NGC 3766 is a very dense open cluster and shimmers like a Pearl which is how it got it's nickname, "The Pearl Cluster."
This is a good binocular target but can also be glimpsed with the naked eye from dark skies.
The image in this page was obtained by Ray Palmer. It was taken on March 3rd, 2006 from Perth, Western Australia, with a Takahashi Epsilon 160 mounted on a Losmandy G-11at f/3.3, exposed for 20 min on Kodak Elite Chrome 200 unhypered.
