This picture shows you a corner of south west of the constellation of Monoceros.
Just western part of γ Mon, you can detect several faint reflection nebulae in a span of about 1 degree.
It's considered that those nebulosities is emitting by reflecting light of stars.
All of those have about 1 to 3 arc minutes in apparent diameter.
The gaseous matter of this group of nebulae constitutes the outer region of the Orion Association that is spread out in the constellation of Orion just west of this field.
