This horizon-to-horizon image takes in a broad sweep of the southern Milky Way from Orion to the Southern Cross.

At upper left shines bright Jupiter in Taurus and the stars of Orion, upside down. To the right of Orion is Sirius in Canis Major, the brightest star in the night sky. To the right of Sirius above the Milky Way is Canopus, the second brightest star in the night sky and one we don’t see from up north. The two satellite galaxy Magellanic Clouds are at upper right. Below them is the bright Milky Way through Carina and Crux, the Southern Cross. Alpha and Beta Centauri are just above the dark trees at right. This is the entire Milky Way you see on an early austral summer night from down under.

What stands out is the huge red bubble of gas called the Gum Nebula in Vela and Carina. It is strictly a photographic object but shows up well on red-sensitive digital cameras.

I shot this with a filter-modified Canon 5D Mark II camera and a 15mm wide-angle lens on a mount tracking the stars. It is a stack of four 6-minute exposures, shot from Australia a few nights ago under nearly perfect sky conditions.

  1. Did you see (or have you ever seen) the light bridge that spans from the LMC to the Milky Way? It’s supposedly visible under Bortle Class 1 skies. Your photos are beautiful and inspirational, btw.

    • Hi — I’ve not seen that light bridge but I’ll be sure to look next time! I have certainly seen the Zodiacal Band across the sky and the Gegenschein. But those are easy in a truly dark sky.

  3. Absolutely amazing, Alan – grand vistas!
