I also observed the two comets Saturday night, from a dark-sky site in the
Southern California desert. Agree with Steve's comments; Tuttle and M33 did
look similar, but the comet had noticeably higher surface brightness than the
galaxy. Were in same field of view with 10x50 binoculars; could not see Tuttle
naked-eye.
If anybody images Tuttle and M33 together, please post a link. Thanks.

Comet Holmes is much dimmer than before, I would guess about 4.5 magnitude.
It is larger and lower surface brightness. I can still see it with just
naked eyes, but it is fainter than the Double Cluster and somewhat larger.
Naked eye I say it is about the same brightness as the Andromeda Galaxy.
Using the ED80 refractor and a 27mm Panoptic eyepiece gives a nice view.
The comet takes up about 60% of the field of view and the central elongated
bright section is still pretty easy to see.
It took a while to find Comet Tuttle, but once we did it is also nicely
displayed in the 80mm RFT. This comet is round with a bright core. Averted
vision makes it much larger in size. In my widest eyepiece, a 35mm
Panoptic, Comet Tuttle and M 33 are at the opposite edges of the field of
view. They look rather similar.
