Yes I'm a big an of both this cluster (nice pic) and in particular the star Zeta Puppis (Naos). It is in fact my most favourite'st star of the lot and I was just admiring it while bobing around in the pool outside (its still 27 deg C here just before midnight).

There is some new info about this star here:

Courtesy of Jim Kaler that paints the picture well. It is probably the most powerful star within 1000 ly of the Sun, the earliest O-type (O5) bright naked eye star in the sky, the 2nd brightest O-Type star in the whole sky after Zeta Orionis and shines with a total luminosity 360,000 times greater than the Sun.


Best,
