If you're planning to use the camera connected to the C8 for prime focus work, you'll also need a T-ring and a prime focus adapter. This allows the camera to be used anywhere a 2" eyepiece can be used.
There is also a a 2" adapter for the C8 that replaces the visual back and allows you to use a 2" eyepiece/diagonal and of course the t-ring/adapter.
