Barnard's loop in the giant molecular cloud of Orion

This is an unusually very wide field picture centred on the great Orion nebula. The Moon would look very small on this scale in fact similar to M42, the brightest object in the lower centre. Barnard’s loop is probably the result of a supernova explosion and is lit by the young stars of the nebula. The arc diameter is about 600 arc minutes. It is also possible to see the Horse Head in the centre and part of the Rosette in the top left corner.
