How Does a Meridian Flip Affect Your Image Framing and Alignment?

A meridian flip rotates your field of view 180°, requiring reframing and recalibration for accurate astrophotography.

After a meridian flip, your telescope’s field of view rotates about 180 degrees, flipping your image upside down or reversed left-to-right.

This means your target and guiding stars will appear shifted, requiring you to:

  • Re-center your target for consistent framing
  • Recalibrate your autoguiding system
  • Check polar alignment to maintain tracking precision
  • Rotate images during stacking to align pre- and post-flip frames

Planning your framing with the flip in mind—such as framing slightly off-center—can save time and keep your session running smoothly.
