The Meridian Flip can be one of the most painful and annoying parts of an imaging session. It interrupts the imaging run, and is likely a big point of failure.
At best, it just wastes a bunch of time.
Automating it can alleviate a lot of the pain. Sequence Generator Pro does a good job of this, using Plate Solving to make sure you're back on track quickly and with a minimum of fuss.
This is a quick run-through of what happens during a Meridian Flip in SGP, and once you've got it working properly, you can let it go and know that you can do it confidently in future.
