I attach my image of Mr G taken last night but it’s only a 20 minute total exposure so doesn’t show things as clearly as yours. The fan shape is there plus a hint of the extension. I agree with Grant that the fan shape has been there a while. Indeed Mike H commented on it when he posted his image on 23rd November. However I need to check more of my images but I don’t think the fan shape was there before 9th November. So maybe the nebula is trying to return! I’m sure we will keep checking!
