FW, I humbly apologise for saying Orion and not Orions Belt.
The explanation (tho' I know you won't take this as an adequate excuse) was that I was playing with the idea of making the title catchy, Orion Ornot?
I also apologise for not making it clear there is in fact no Orion nor a Belt but merely an optical illusion and burning clouds of gas.

Actually, the belt is a fair bet to have been taken most note of, I think, rather than the larger constellation patterns. It, like the Pleiades sticks out more clearly than all other constellations, being so closely grouped. I don't "see" the plough as a whole thing quite as readily as the others jump out at me.
