If you are using an external flash drive to save your images and you plug that into a computer, you will see the following directory [folder] structure:
ASIAIR
-- Autorun
-- Live
-- log
-- Plan
-- Preview
-- Stacked
-- Video
The Autorun and Guide (PHD2) logs will be in the log directory.
To look at a Guide log (and make some sense of it) you need to download and run the PHD2 Log Viewer. You can get it from here:
https://openphdguiding.org/phd2-log-viewer/
In looking through my logs, I always have a corresponding Autorun and PHD2 log file although in one case I started playing with guiding about one half hour before midnight and started the Autorun imaging after midnight so they had separate dates on them.
