currently you can use the autoguiding by connecting a guiding camera with ST4 cable to the Star Adventurer and running PHD2. You must select "On Camera" in PHD2 for mount and then this program will do pulse guiding the Star Adventurer mount. You can use Drift Alignment in this setup with PHD2 if you can't see the Polaris from your observation site. That is what I do. In my case, I put a Skywatcher Merlin mount on the top of Adventurer for slewing to avoid manual fiddling with a ballhead.
