This is an animation of 3 sessions, with 6 months between each, a few years ago. I had heard that the pulsar in M1 was creating a shockwave and that we might be able to see it. So I collected the images I had of M1 (I happened to have imaged it 3 times) and created an animation of its centre. It's subtle because ideally I would have needed data over a longer period of time and better equipment, but I think you can see the shockwave move top left (arrow), top right (arrow), and bottom right (which I missed when I created the animation).
