Maik,
Good luck tomorrow. I know you are very experienced but be careful. I'm only risking a camera, not my eyes!
I've processed the full video now and the result is here:
I've tried to estimate the magnitude by measuring the intensity in a 40 arcsec diameter aperture and comparing it to a video of Venus taken just before the comet observation using the same settings. Assuming Venus is -4.6 and using a correction of 1.0 mag for differential altitude (Venus was at 29 deg, the comet at 10 deg) I get -0.8. That doesn't really seem bright enough given how prominent the comet is on the image but that is what I get!
Nick.

Nick,
this is really great, great images, thank you. I might try it visually tomorrow as we have sunny skies predicted. Should gain maybe 2 mag in the next 24-48 hours.
