The comet continues to rapidly fade, so I did a 550sec exposure this morning with a 16mm fisheye (on 35mm, but equivalent to 24mm on the D200). Over 23deg of tail is still visible, although it is no longer obvious, and would easily be missed by someone who wasn't familiar with the sky.
Larger version, and maybe another image later if it looks any good, here:
