Description: Omega Centauri. This is unbelievable! There are several thousands of stars all over the field and only the brightest ones are placed right in the sketch. The cluster is strongly elliptical in NWW-SEE direction and there are several figures visible among the stars. The most eye-catching is a footprint in the middle of the cluster, and it's obvious. The core is very large and doesn't have brighter center at all. The brightest stars are ~11 mag.
