If you want to do a Meridian flip "early" you can only do that manuallyI forgot to state also that there is a better alternative to doing a Meridian Flip "on-time" The PMC-EIght and driver is fully capable of tracking up to an hour past the Meridian (depending on mount/scope configuration) and if you are in the middle of an imaging run, it is best to not schedule the Meridian flip until at least 5 minutes past the Meridian. I think that this should be possible if you are using an automation program like NINA or APT (I don't know). I use MaxIm dl and it allows me to delay the meridian flip. This is a better approach than trying to do the flip "early" and will not run into the issue when trying to do a plate solve immediately after the flip causing a pier-side miscalculation.
