Comet not aligned

Hi, 
I'm following the steps of *C2022E3(ZTF) OSC example*
and the comet is not aligned when doing the CometAlignment process. 
When doing the Blink it keeps jumping. What could be happening?
 Thanks in advance.

    Hi Alex,

    Assuming you do not have a meridian flip in your data... (you can't use CometAlign with a flip)- then it is likely the centroid process. If you turn off PSF Fits, it will be a linear fitting of the motion of the comet. You can also force the fitting with PSF fits by clicking on every singe frame! 

    If you really can't solve this you can upload your star aligned images and I can look at them.
