Description:
At ~ 8° of the Pleiades.  The observation of this double gave me much satisfaction;  in the first seconds of the observation, the secondary remained invisible.  But by observing a few minutes moreover, it ended up appearing.  The gap in magnitude between the components is 3, which made more difficult the separation of the members of this double star.  The primary star is white-yellow and the secondary is too weak to see the color of it.
