Here's my procedure for quick setup and polar alignment with the HEQ5 Pro:
  1. Upgrade the hand controller to firmware version 3.35.
  2. Set down the tripod, use a compass to make the South leg (labelled "N") point south, compensate for the magnetic declination at the location.
  3. If the ground is reasonably level don't bother with levelling the tripod.
  4. Add the mount, counter-weights and scope. Adjust the mount elevation using the azimuth scale.
  5. Turn on the mount, enter location, date, time and DST flag, be as careful and accurate as possible.
  6. Perform a two-star alignment. After successful alignment the hand controller will display the polar alignment error in azimuth (Maz) and altitude (Mel).
  7. If the azimuth error is larger than a couple of degrees yank the tripod around a bit. If the displayed Maz error is positive the South leg needs to be pulled to the West (right), if negative, to the East (left).
  8. Likewise for altitude error, but the error is shown with the wrong sign (Southern hemisphere bug I presume). If the Mel error is positive the mount needs to point higher, if negative it needs to be adjusted lower.
  9. Perform another two-star alignment to a) confirm that the adjustments have been in the right direction and b) that the mount is within a couple of degrees in alt and az. If not, repeat the previous three steps.
  10. Use the Polar Alignment function in the Alignment menu. Refer to the SynScan 3.35 manual for details. Repeat until the polar alignment error is acceptable.
  11. Do a final two-star alignment and start observing!

This works for me every time, and I get to sub-minute alignment errors within minutes after setting up the mount and scope. That's as far as I take it for my visual use. For imaging you can go nuts and repeat step 10 for as long as you like

Cheers
Steffen.
