Hi Deimos. Welcome to the forum.
There are a number of ways to polar align your scope. Do you actually use the polar alignment scope to find the SCP? I've known a few people who have had LX75s and have found the polar alignment scope next to useless unless you actually know how to use it
Bit of an ask for someone who is new to the mount. Also have you trained the drives?
The Autostar should take care of most inaccuracies when you do your alignment, but of course the further out from the pole you are the less accurate it is going to be. The best suggestion I can give you is to learn to drift align. It isn't difficult to learn and you will need to be able to do it for imaging anyway. There is a great simulator available. Check out this post with the
simulator link
Once you have drift aligned a few times you get a good feel for where south is anyway. Btw for visual work you don't need to be accurate to the arcsec, an alignement procedure of 15 min will probably get you accurate enough for the autostar and visual work.
Alternatively to the simulator you can join us tomorrow week at Astroron's for our monthly Cambroon (near Kenilworth) get together. There is a map at the top of the Star Party and Observing Session forum. Check the events calendar for when it's on. You would be more than welcome and staying overnight is not a problem. Pm me if you'd like more details.
