Stacking not failing but bad results

Flix19

Hey everyone,
my s30 shows some weird behavior.
Sometimes it stacks images in a wrong way. The stars look like there are 3 of each.
Often, a go to another star them returning to the original target helps. It does not matter which exposure time I set the Seestar to.
Here is a picture of SH 2-142.
Shot in eq mode with 20 sec. 209 frames.
Can anyone help me with it?

This issue is likely caused by vibration. You can try switching to Solar System mode, select GOTO the Sun or Moon, and enable tracking to check if the image is shaking.
If it’s not shaking, please record a video showing the issue and share the link with us, or contact us through this link https://support.zwoastro.com/
You might also try using the device in a different environment to see if the problem persists.

Support@Seestar Okay thanks. I tried it with the sun and it looks like it’s wobbling up right and down left. Just like the offset in the star picture. In one moment of the video there is a strong jump where the sun gets a few millimeters off the center of the frame. The Seestar centers the sun a few miliseconds after that back in the middle of the frame.
What can I do to stop this movement?
