Outstandingly more interesting in the NIR than in the visual regime, especially the cluster!
Me and Dana have been obsessing about the cluster Westerlund 2 in a number of threads:

The might call me madbadgalaxyman, but Dana is definitely the Mad Cluster Man; he will spend multiple nights trying to glimpse a vanishingly faint Star Cluster, and he looks up all of the science about his target of observation.
