Thanks LA3QMA for your reply.
The initial position of the level may not be accurate enough with some factors, at this point you can do a manual calibration.
You need to remove the Seestar from the tripod and place it on a flat surface (you need to make sure it is level).
Then go to the app and click “Advanced Feature--Level sensor calibration” to calibrate the initial level position, which is what Seestar considers as This is what Seestar considers to be the “0” degree horizontal position.
When you are shooting in other locations, first adjust the level in “Adjust Level” by using a tripod.
Thank you.
