This is a closer view - with a 50 mm lens - of the wider-angle image seen here:

Here, Orion's orientation is familiar to northern hemisphere astronomers. The reddish curve of Barnard's Loop is obvious in this view. The brilliant star Sirius - bloated and over-exposed in this photo - is at bottom left. The large reddish circular Rosette Nebula in Monoceros is at the top edge just left of centre.
