How does it work, what is it for?
I understand that the purpose is to sync internal coord system with real, Ok. But seestar tutorial says:
When the Seestar is successful in GoTo, when the celestial body is in the center of the screen and the centering is successful, the system will automatically Sync once.
If it syncs after goto then why do we need button for manual sync? Or does seestar sync after first goto only? And after that we can sync manually at any time if we wish to improve goto accuracy, especially if we moved to the other part of the sky.
