Thanks for the images, Dean. Your wide-angle shot really shows well the
relative positions of the comets and galaxies. In that photo, Tuttle is in
quite a different position compared to when I looked at it just the night
before -- this comet is really on the move! Also striking is the color
difference between the comet and galaxy, which wasn't apparent through my
binoculars.
The spaceweather.com gallery also has a bunch of images:

Hi All-
Don't know if anyone else had a chance to image last night, but will throw
in my efforts... Haven't had a chance to work on flat fielding, but here
is a 2 minute exposure of comet plus M33 with the C-14 + Hyperstar + Canon
20Da (660mm @ F/1.9):

Also, with all these bright things in the sky, here is a shot with a 35mm
lens @ F/4 for 3 minutes (had to work to fit them all in, north is towards
the lower right). You got your Tuttle plus M-33, Andromeda Galaxy, Comet
Holmes plus the Double Cluster taking up the 4 corners of the shot:
