I'm a newb here but have never had the problem you mention, so maybe I am confused at what you are doing. After the 60 degree slew and that plate solve I NEVER, UNLOCK and then rotate the mount back to the home position. I finish the PA from the 60 degree position, after I hit the LETS GO command. Once I'm done with the PA final adjustments from that position, ( 60 degrees from the original home position ) I either tell the mount to go to home position ( WITHOUT UNLOCKING IT ) or try to use the GO TO command from where I finished the PA. It seems to me that by unlocking and freely rotating your OTA your mount still knows where it is pointing, but it also thinks your OTA is pointing that way too. By unlocking and rotating it, there is now a 60 degree difference between them. My guess at what is causing your problem. But being a newb myself Who knows :-))
