Meridian Flips

Parent Previous Next

Sequence Generator Pro, when used with PHD2 or better can provide you the ability to perform an automated meridian flip.  This function can be run manually, by clicking a single button or you can let the sequence decide if it needs to run a flip based on settings you provide.


A Brief Summary of Automatic Meridian Flips


  1. Stop auto guiding: Simply sends a command to PHD2 requesting a stop.
  2. Flip the mount: Send a signal to the mount to flip sides.  This  is based on input that provides the number of degrees past or before (negative values) the meridian to invoke a meridian flip during a sequence.  Not all telescopes allow for setting of SideOfPier.  For these telescopes it is best to always use a positive value.  For details take a look at the telescope control panel page.
  3. Perform auto centering (optionally): Performs a precision centering to ensure that your target is still centered on the other side of the mount.
  4. Restart guiding: Send a command to PHD2 to automatically select a guide star and resume guiding.
