astrosatch But that wasn't the issue I started with in this post.
I thought you mentioned "periodic swings?" Perhaps you mean random swings? "Periodic" in the engineering world implies an oscillation (i.e., something with a period).
Anyhow, it is odd that the correction signs were switching without a pier switch.
Try recalibrating and see if the problem goes away. If so, ask ASIAIR to always recalibrate after a meridian flip.
FWIW, I do not use auto meridian flip. I always control the telescope myself -- part of the charm of a technical hobby is to be involved with the technical aspects, instead of letting the telescope take "selfies" by itself. I avoid anything in ASIAIR that has the word "auto" in it. Even when they work, they are suboptimal (e.g., auto centering never centers sufficiently, auto focusing that does not focus critically, etc). Good enough for the selfie crowd, but insufficient for serious hobbyists.
