Meridian flip

[Jezphil]

Just checking here as a I think I discovered the answer to this the hard way on Friday night. I took some subs and with my software marked three key stars and saved those markers and coordinates. In the middle of the session I did a meridian flip. I loaded in the x-marks-the-spot markers to align the post-flip stars with the pre-flip ones but none of the stars seems to match. I realise now this must have been because my camera would have been turned upside down by 180 degrees during the flip. Would that make sense?

Yes.

Yep.  If you rotated one of the post-flip images, it would line up fine.

Thank you!

Before I automated things that's exactly how I used to do it
