PONIATOWSKI'S BULL OF OPHIUCHUS
The vee-shaped set of stars pointing downward at the center of the
picture, reminiscent of a bull's head and horns and set in northeastern
Ophiuchus, is the defunct constellation -- now an asterism --
Poniatowski's Bull (Taurus Poniatovii), which honors
Stanislaus Poniatowski, King of Poland from 1764 to 1795.
Flamsteed numbers all belong to
All but 70 Oph were once thought to be members of the cluster Collinder
359 (as was Gamma Oph). Only 67 Oph survives membership,
making Poniatowski's Bull something of a false cluster like
Fast-moving Barnard's Star, not visible in the picture,
lies within the labelled circle. To the right of the
Bull is the open cluster IC 4665.
