Three faint comets.

Hi,
Thought I'd give some faint comets a go last night 12-06-2012.
The magnitudes listed are from guide 8.
1. Comet Garrard C/2009 P1. in Cnc. mag 10.9
2. Comet Loneos C/2006 S3. in Oph. mag 12.2
3. Comet McNaught C/2009 F4. in Dor. mag 14.3.
Comet Garrard has been a consistent performer, imaged it back in September 2011 and I wanted to image it one more time. The galaxy in the field is UGC 4740 mag 14.8.
Comet Loneos, shows a well defined nucleus and sporting a small tail.
Comet McNaught was a real surprise at mag 14.3, I was happy to get anything, this even shows a small tail.
All images are at ISO 1600 5 x 120 sec exposures, no auto guiding.
Telescope 8" f/4 astrograph on a HEQ Pro 5 mount.
Unmodded Canon 1100D at ISO 1600
5 x120 sec subs ISO 1600
Stacked in DSS and post process in Phototshop.
Cheers,

Justin.
