Update: Saw it! With my eyes it's just a centerless cloud to be seen near Mirphak through binocs or by passing my eyes over Mirphak to activate peripheral B/W vision, but if it blows up tomorrow I will have seen it. Clue: the last link of the handle of the Little Dipper points more or less at Mirphak.
