Very nice picture by the way
Unguided means that you allow the mount to guide using its motors without using an external camera to provide corrections for periodic error. Some mounts have to be guided with anything longer than 30 second exposures because the periodic error is so erratic it would cause the image to be blurred
Hope this was the answer you were looking for
Kind regards
