Hi,
Here's some more comet images plus animation of C/2011 K5 LINEAR, for 3/1/2013.
First C/2011 K5 LINEAR animation, this comet is really moving and I was limited to 30 sec exposures at ISO 3200 to stop trailing. I decided to supply an animation, 31 sec run time, real time 18 minutes that includes timing intervals. I also used registax to stack on the comet, for a single image.
In that time it moved 3.8 arc minutes.
Animation.

C/2012 F6 Lemmon is a colourful comet, really putting on quite performance.
Again here's the link to Michael Mattiazzo's comet page for further info.
