Hi Martin
Keep the handcontroller for visual work, but for AP you're better off to get EQMOD going. You'll need a dedicated cable, something like:

Connect the HEQ5 back to a USB hub (to direct to your laptop if close enough) and your guidecam back to Hub or laptop via USB. Then use PHD2 to take care of guiding.
What guiding hardware do you currently have? (camera, scope/OAG)
