The Seven Sisters
This is 3hrs in 10 min subs on the Seven Sisters/Pleiades/Subaru/M45 Very gentle processing, bit of HDR wavelets and NR then a little saturation boost. M45 is an open cluster, visible to the naked eye. The light from the hot blue stars is reflecting off the nearby dust giving the lovely delicate detail. This dust is not actually part of the cluster but merely in the area of space the cluster is currently passing through.
