Actually there’s another nebula, making three all together. The Orion Nebula proper, also known as M42, is the large spread wings brightness in the lower center. Separated from M42 by a narrow dark lane is the tear drop shape in the slightly left upper dead center, M43, apparently also known as “Mairan’s Nebula”. And finally in the upper third is the dimmer”Running Man” Nebula, in the top.
I’m getting better at this, but it is an incremental process.
