2 or 3 star alignment only gives the mount a model of the sky for Go To
purposes, nothing to do with PA. I have found the built in PA function fiddly and time consuming.
I suggest you Google DARV, like I did. It is the easiest way of polar
aligning I have come across. Another possibility; are you lining the mount
up with true south, as you should, and not magnetic south.
With an ED80 on a reasonably aligned mount you should get an
acceptable percentage of subs at around 90 secs, and with really good
PA, about 100-120 secs, or even longer.
