On the left is Mimosa the second brightest star in the constellation Crux, the southern cross at Magnitude 1.25 is the 19th brightest star in the sky.

Very close to Mimosa there's a blood-red star, that's DY Crucis a carbon star! Carbon stars are the reddest stars in the sky. Mimosa and DY Crucis are a beautiful blue-red pairing in the sky.

On the right side of the photo lies the beautiful star cluster known as the "Jewel Box" (NGC 4755). The cluster is centered around Kappa Crucis an orange star contrasting with the other members of the cluster.

How the sky looked about one hour before sunrise, the waning crescent Moon is just two days before new Moon. Two planets are aligned over the ecliptic: Jupiter and Mars. Zooming into the photo Jupiter's Moons are visible trailing the planet.

The great display of planetary conjunctions of May ends, the thin crescent Moon and Venus are still visible and bright while the first rays of sunrise create a shadow in the sky.
Buenos Aires, Argentina.

The bright full moon of May 2012 above Rio de La Plata with a colorful corona around it.

This photo is the best representation of what I saw with my own eyes, a very beautiful scene.

To create this with the camera I had to take 3 exposures: one for the water, one for the moon and one for the Corona and then combine them.

Our eyes adapt to light so quickly and the camera can't do the same trick so sometimes it's hard to show in a photo what you saw with your eyes.
