Heh, PP involved mainly waiting for the CPU to do the crunching.
Anyway, the image FOV is 1.36 x 0.89 degrees (1 deg 21 arcmins X 53 arcmins), and that would make the comet at its widest at that moment a little larger than the full moon.
Of course it wasn't visible as such to the naked eye, it required at least a pair of large binoculars to spot the brighter center of it.
