Thanks for the very clear explanation Andy. I actually have been connecting to my mount as an Aux Mount since upgrading to the newer PHD2 development build, so I’d already stumbled into that one. I didn’t realize that was what Ken was talking about with regard to recalibration. I had no idea about Auto Restore Calibration though so that is a big help - I will do a good calibration near Dec 0 and set that option - that’s assuming that clear skies return within my lifetime.
Good to know I can keep running in the configuration I have now or I can ditch the ST-4 cable and run using a single ASCOM connection in the future. I assume that, other than losing a cable, there is no real difference between the last two options? Again, thanks for explaining this so clearly.
