If you setup in the same position everynight, spend a bit of time (a couple of hours of one night) to do an accurate polar alignment. Learn drift aligning, if you don't have the mount connected to a computer. Mark the position of the tripod legs on the ground, or put a line on the ground which matches the back legs of the tripod. Do this once and every night you go out, as long as you havent moved the AZ and Alt bolts on the mount you should be very close to polar aligned. Good luck hope you get there.
