Interesting Trev,
I suppose it's not outside the realms of possibility that it's a recently
illuminated part of another clump of dust. AKA McNeils Nebula.
I hope it is, then it will be named after you!!
I'll certainly take a widefield shot tonight of the spot.
Could also be a lens flare from Rigel, did your camera orientation
change at all compared to where Rigel was in the frame?
That usually identifies a lens flare.
regards,
Steve.
