Observing podcast: Open cluster NGC 7261, globular cluster 47 Tucanae, and Bond's Galaxy

47 Tucanae
The Southern constellation Tucana is probably best known as the home of the Small Magellanic Cloud, one of the satellite galaxies of the Milky Way. But Tucana also hosts another famous object that shines thousands of lights, like a magnificent, oversized diamond in the sky: the globular cluster 47 Tucanae. More popularly known as 47 Tuc, it is surpassed in size and brightness by only one other globular cluster, Omega Centauri.
