Agreed, but I have an observatory 500 feet away - and the delay of having my home computer process guiding is too much. I have to use PHD2 or use VNC and run KStars at the observatory.

It runs on the mini but through the rPi. Using the rPi as server to Mac kstars client the internal guider works fine. I have a wired Ethernet connection so the lag for guide camera image files is not really a problem. My wording was a little ambiguous kstars and ekos run on the Mac and control everything (including auto guide). The rPi serves up the devices (mount, cameras, etc) to the Mac.
