As a rookie astrophotographer, I have recently acquired a star adventurer mount. Seeing the port marked "Auto Guider" it sure seems to me that the manufacturer intended the mount to be used this way. But the documentation on this capability or connection is non existent. I bumped into something called phd2..it seems there is hope. Do I need a guide scope or can the mount take direction directly from phd2? Obviously i am somewhat confused. Any guidance out there? Thanks in advance.
