This wide-field image shows the open star cluster NGC 3766, which seems to float weightlessly in the universe. It is a bright object that can be seen even with the naked eye and is very impressive in a medium-sized amateur telescope.
wikipedia:
NGC 3766 (also known as Caldwell 97) is an open star cluster in the southern constellation Centaurus. It is located in the vast star-forming region known as the Carina molecular cloud, and was discovered by Nicolas Louis de Lacaille during his astrometric survey in 1751–1752. At a distance of about 1745 pc, the cluster subtends a diameter of about 12 minutes of arc. There are 137 listed stars, but many are likely non-members, with only 36 having accurate photometric data. It has a total apparent magnitude of 5.3 and integrated spectral type of B1.7. NGC 3766 is relatively young, with an estimated age of 14.4 million years, and is approaching us at 14.8 km/s. This cluster contains eleven Be stars, two red supergiants and four Ap stars.
