Losmandy G-11 + PHD question


I have a Losmandy G-11 Gemini I level 4 mount and a Takahashi FS-102. I need to autoguide it with PHD + William Optics SD-66 + QHY5 camera.

Question: what cables or accesories do I need to connect my computer's PHD to my G-11 Gemini panel and in which Gemini's panel conectors?

My mount is already controlled with my computer conected with the Gemini's RS-232 plug.

PHD can be used for pulseguiding. That means that the guide corrections are being send through the same cable that you're already using for controlling the mount. So you don't need any additional cables if you choose to pulseguide.

If you are using the QHY5 to guide, there is a cable connection on the back of the QHY5 camera that goes to the autoguide port on the G-11.

That is all you need to use PHD to control the G11 when guiding. In the setup of PHD use "On Camera" as the mount setting. I use that setup.

I don't even connect the mount to the computer.

Thanks jjongmans and Dwight. I will try both methods, and check which one is easier.

Good to hear I don't need the GPUSB, less cables to deal with.
