The Great Orion Nebula M42 (NGC 1976)
Diffuse Nebula, distance: 1300 ly ; apparent magnitude: 4.0 ; apparent size: 85x60 arcmin
Discovered 1610 by Nicholas C.Fabri de Peiresc and independently 1611 by Johann Baptist Cysatus. Trapezium cluster which was found as multiple star by Galileo Galilei in 1617, is among the youngest open clusters with stars still forming in this stellar nursery.

De Mairan's Nebula M43 (NGC 1982)
Diffuse Nebula, distance 1300 ly ; apparent magnitude 9.0 ; apparent size 20x15 arcmin
Discovered 1731 by Jean-Jacques Dortous de Mairan, separated from the great nebula by an impressive, turbulent dark lane, and is lying 7 arcmin north of the Trapezium Cluster. M43 surrounds the irregular young "nebula variable" NU Orionis

Running Man Nebula (NGC 1977), NGC 1973 and NGC 1975
Reflection Nebula ; apparent size: 20x16 arcmin
Discovered 1785 by William Herschel, a region of predominately blue reflection clouds of hydrogen.
