Hi Rusty..
I used to align with 2 stars but when i was close to believing i was polar aligned, i would align with 3 stars and everything never as it seemed....alignment was definately not the same as was indicated by 2 star alone.
I tried 20 min subs last night for the first time...the stars at the edge were marginally elongated...
I am not a big fan of aligning the Heq5 pro...it isnt bery user friendly especially the elevation axis....
Is there some sort of plate that can be mounted between the tripos and mount head that is motorised and can be used to uncrimentally move the mount head in alt az for accurate polar alignment?
hmmm i am not sure if i should move this thread to equipment discussion....

yes mine changes depending upon the stars. I've had all zero's across the board a few times, whether or not that is actually a reality is another question all together.
I know there are some people who go with the 3 star alignment process but I use 2 star alignment. From memory the manual suggests 3 star alignment to make a more accurate map of a certain part of the sky and to help eliminate cone error.
