Pegasus Cluster
This is an Open Cluster, but too impressive not to include. As often with diffuse nebulae, clusters of young stars may form from the nebula's dust/gas and other material. If you have a look at the Lagoon Nebula under Nebulae, you can see part of this cluster at the top right hand corner of that image.
