OK, the other nights were rubbish, tonight was the real thing! Amazing comet.

I took many shots of the same FOV for each of the comet shots, to be able to stack them later, so should end up with nice big prints of reasonable quality which I'm really looking forward to. The above are raw individual frames.
I'm very happy with the results. Amazing comet. The other nights were "oh yeah, that's pretty good", tonight it was "wow, that's really a bright, big comet!".
