Marc is absolutely right. A C14 weighs in at about 22-23 Kgs. A G11 is rated as having a capacity of about 25Kgs (or thereabouts) so you're already at or close to the max rating for the mount. This means that with the addition of some imaging gear, you will almost certainly exceed it. This will stress the mount and, for imaging at prime focus, make it susceptible to shakes and shudders. Guiding will be difficult.
I suggest that you consider a smaller and lighter scope or a heavier mount.
I have imaged with a C14 and guided with it, and got very pleasing results, but on a Titan mount.
But, if you really want to go ahead, you'll need, as a bare minimum, a Celestron .63 reducer, an off-axis guider and guide cam, and as a starter camera, a DSLR with the necessary T-ring connector.
An alternative is to fit a Hyper-Star adapter (if your C14 has been modified to accept one) and image at f2.8 or whatever it is. That will make it less susceptible to vibrations. But the Hyperstars are heavy beasts and your weight problem will be somewhat worsened.
