Hi Ryan, Your focus seems to be off. How are you focusing? Does your 5D have "Live View"? If so it makes focusing easy by enlarging stars by either
5 or 10x.
I have attached a pic of similar scale to yours to illustrate how your stars should look.
You are up against it using an f/10 scope;for comparison the attached image is a single 10 sec frame using ISO 1600 with an 8" f/5 scope.
