Jean,

Hier een korte nota van Bill Gray in zijn Guide list. Misschien
noemenswaardig:

About the missing star, SAO 76188, in Pleiades Cluster: to my
knowledge,
this is the brightest star missing from Tycho, Hipparcos, and GSC. I
have hopes that Tycho-2 will repair this omission (as well as omissions
of some fainter stars.)
