I think these are all fabulous pics. This wonderful Jewel Box cluster is one of the true gems of the southern skies, and it has captured my imagination ever since I first saw it at Sydney Observatory. This history of its observations, and the coloured star have let it keep its endurable popularity and legacy. (Could they be running out of the usual northern targets I wonder?)
The only open comment to make is that this open cluster was a perfect cluster to choose, because it is relatively small in size. Love the fact that the the camera still couldn't fit it all in.
Another interesting thing is they leave out the most obvious candidate!
The image neglects one member of the cluster, which is well away from the asterism. This is the star HIP 62646, of 5.7 magnitude, lying some 15 arcmin away — roughly towards β Crucis / Mimosa. It is the brightest star associated with familiar 'A' shaped asterism. Those here might be interested to read part of the southern page about the cluster and where this "missing star" is placed. I.e.
❝NGC 4755 — THE JEWEL BOX – "The Jewel of the South", which is broken up in several parts.
