Some resources say no and other say yes.Hi Euan,
There are two ways to connect your mount to your guiding system via the universally used PHD2 Guiding software. You can use the legacy ST4 connector on the mount with an ST4 cable to your camera. This is called "On camera" in PHD2. OR, you can eliminate the use of another cable by using the PulseGuiding API in ASCOM by selecting ASCOM in PHD2 for the auto guiding connection. PHD2 makes use of the USB connection you have to your mount already to send pulses to your mount.
The ASCOM PulseGuide function is the best way to go. No need to use the legacy ST4 connector anymore.
