Comments: This is likely the most famous cluster in the heavens. Also called the Seven Sisters, most people can see only six stars with the unaided eye, but reports of up to 18 visible stars have been documented. Many people don't realize that M45 also contains a nebula. This nebula is of the reflection type (blue) with only a slight emission component (pink). This star cluster is close, by cosmic standards, being only 407 light years away.
