Everyone from the north who sees this area of sky for the first time quickly realizes just how much better the sky is down south. This is the most spectacular region of the deep-south Milky Way, as it passes through the constellations of Carina, Crux and Centaurus.

Dead centre here is the symbol of the southern sky, the Southern Cross. To the right of it glow the reddish nebulas of Carina and Centaurus; to the left of the Cross lie the dark clouds of the Coal Sack and the pair of brilliant stars, Alpha (on the left) and Beta Centauri. Alpha is the closest bright star to our solar system.

This one field contains much of what makes the southern sky so memorable and a mecca for any backyard astronomer. You haven’t lived an astronomical life until you’ve seen this part of the Milky Way, accessible only from southern latitudes.

I took this shot last night, May 4, 2011, using a Sigma 50mm lens and a modified Canon 5D MkII camera. The image is a stack of four 6-minute exposures at f/4 and ISO 800, plus a stack of two more 6-minute exposures taken through a soft-focus filter, with those images layered into the final Photoshop image to add the star glows and make the constellation outlines, like the Southern Cross, pop out.
