" I have got very interested in this issue of why it is that NGC6231, which is at a (rather uncertain) distance of some 5000-6500 light years, and which is so remarkably luminous that it is a bright object in amateur telescopes despite its considerable distance, seems to be just about the only such "young & luminous, very OB-star rich" cluster in the Milky Way between Scorpius and Circinus."
I just blew $90 on a recent book, so as to better understand these issues regarding star formation regions, star clusters, and nebulae, in the southern Milky Way!!
The book is called "Handbook of Star Forming Regions : Volume II, The Southern Sky", edited by B. Reipurth(published in 2008)
This isn't going to be an easy read, as it is an 890 page professional monograph, but I just love digging up these kinds of details!
(For many years now, I have only studied galaxies external to the Milky Way, but I once did spend some years as an enthusiastic student of Milky Way structure.)
