Tech@ZWO It seems that when using ascom and phd2 you can adjust the AM5 guide rates, and in ASIAIR you can adjust all other manufacturers worm and harmonic mounts guide rate… so it is handicapping and limiting to your own mount that it cannot be done to help improve guidng for the AM5 mount when using Asiair to run it. It is an essential feature especially if the mount has a very sharp PE slope.
