Tried tonight with C11, 2x Tele-extender, Canon 60D (video crop mode, ISO6400) and I caught it without too much trouble.
Processing was with PIPP, Autostakkert, curves in DPP.
First I tried visually but it was barely visible.
Video is here.
Another attempt, this time with 10" f/5.6 Newt, prime focus (FL-1420mm) on Bartelised Dob mount.
Canon 60D, crop mode video, Pipp, AS, R6 (~2800 frames).
