There's a pretty good comet visible near the easy-to-find constellation Cassiopeia (the big "M" or "W" in the Northern sky). It's brightness is listed as magnitude 5.7, which ought to be visible with binoculars if you aren't too close to bright lights. (If you have really dark skies and sharp eyes and let them dark-adapt for half an hour or more, it might even be naked-eye visible, but I'm not betting on that even up on Mauna Kea!)
This chart might help: you can see that the comet is pretty much in line with the first stroke of the "M" of Cassiopeia. With binoculars you'll probably just see a smudge of light with maybe some elongation. With a scope, who knows?
