Cederblad 51 is a bluish reflection nebula located in the constellation Orion, north of the star λ Orionis (Meissa).
It is part of the Sharpless 2-264 (Sh2-264) complex, which constitutes what is commonly called the *Head of Orion*. This nebula is illuminated by light from surrounding stars, which is scattered by dust particles in the cloud. Its bluish appearance is due to the dispersion of light, a phenomenon similar to that which gives its color to the earth’s sky.
