M78
About this celestial object
The cool reflection of M78 glows in Orion just above the horizon.
M78 is a reflection nebula: fine dust scatters the light of young stars, often appearing as a delicate blue.
At only about 4° altitude and in dense air, the faint sheen remains discernible.
66 frames yield just under 11 minutes total integration at 250 mm focal length and f/5.
