Hello Adam,
yes thats it. but bernhard forgot one important step. autoslew needs to know where the hardware reference marks are. so before you sync to a star you need to put RA and DEC axis close to the reference marks and click "find home position" (i think this is the correct name of the function. or you just klick the house symbol).
after that you sync to a star and klick "set the new home position"
