This emission nebula is lying only 1 degree north of the Great Orion Nebula (M42),
very familiar to astro-photographers because they're capturing one of the most photogenic objects in heavens with this NGC1973 in same flames.
The nebula has been spread out in span of about 20-by-30 arc minutes, we can recognize very complicated gaseous matters in the nebula.
Those hydrogen inter-stellar clouds are same that of M42 and various nebulosities around this field.
