Roll your mouse over the picture to see the Southern Cross stars
Here we see the stars of the Southern Cross and pointers (alpha and beta Cen) recorded in an exposure of about 40 minutes, during which the lens focus was moved from infinity to about 2m in six steps five minutes apart. For a fuller explanation see a similar image of the stars in Orion.
