Description:
Beta Scorpi can be splitted by 36x but they seem very close. With 72x,it is
much easier to split and now colors are easier to see. The faint star is blue
and the bright one seems white instead of yellow(as other people say). It is
said that, under high magnification, the yellow color will be more prominent.

Nu Scorpi is very easily split at 36x. Although it is a double-double like
Epsilon Lyr, I didn't try to split because I don't have enough magnification.
