Here is a great page that has a list of visible comets on a month by month basis, good through the next few years. There are some pretty nice comets in the sky right now and a good 4.5" Newtonian will suffice to get an excellent view of all of the comets listed. Not all comets are listed, and many comets are out there, ready to be discovered.
