Description:
Crux is an obvious naked eye asterism.  The "top" star
is Gamma Crux and is seen as orange, even with no optical
aid.  Comparing to Betelguese, it is about the same tint.
The other star with color in the area of Crux is Epsilon,
also known as Mariposa, Spanish for butterfly.  Because
this star is dimmer than Gamma, I seen it as faintly
orange in the binocs, but not brilliantly colored.
Crux is always smaller than I have in my minds eye.
