The last in my series of star clusters, I found it impossible to avoid halos around the stars in the Pleides despite a few attempts. I can only figure it must be caused by the dust, but can't 100% rule out clouds. This cluster is about the same age as the Double Cluster in Persues and containts hot, blue B1 stars, only this time in the middle of a dust cloud, lighting up the Merope Nebula. Note that the reflection nebulosity has nothing to do with the formation of the Pleiades starts themselves, the stars are just passin' through.
Once again, the dim nebulosity coupled with the fine stars (other than the halos) are courtesy of the GHS script.
