I like the Southern Cross; but I can't help seeing a kite also!

Have you ever seen the Southern Cross?
Every spring, but never in that position, except the time I visited South Africa.
I did visit southern Chile once, but it was late spring, and I was never awake when the Sun was down.
It may have been on a trip to Bolivia when I realized that I took the Southern Cross for granted. All the other tourists around me were floored and amazed at the sight, and I was like, it’s just the Southern Cross.

Out of curiosity, what is that bright star at the base of the volcano, right side. That star looks even bigger than the brightest star Acrux. I've got an old star map from school days long gone by and it says the name is Rigel Kent in the constellation Centaurus. Is this correct?

Rigil Kentaurus is another name for Alpha Centauri, the nearest star (apart from the Sun) to the Earth.
(Yes, Proxima Centauri may be closer, but it belongs to the Alpha Centauri system anyway. Or it probably does.)
Interestingly, Alpha Centauri A is a star very similar to the Sun, a middle-aged hydrogen-fusing G2V star just like dear old Sol. Just a bit brighter a a tad more massive.

Ann didn’t explicitly say, but, yes, that star you pointed out really is Rigel Kent(aurus).
