There has been some excellent advice in this thread. I haven't got much to add, but in an attempt to be helpful I'd say:
- here, on the southern hemisphere, forget the polar alignment scope
- also, forget the RA and Dec setting circles, but...
- do not neglect the Altitude (geographic latitude) scale (on the opposite side of the HEQ5 Pro label), that one has to be set rather correctly, best to start in the right ball park
- try to get your south bearing (the tripod leg labelled "N") to within less than +/- 10 degrees of true south
- put your mount into the best eye-balled home position before you turn it on: counter-weight bar straight down parallel to the south ("N") leg, the scope aligned with the RA axis of the mount
- if your first alignment star is way off and you feel you could get much closer by dragging the tripod around a bit – do so, then start over with the alignment
- pay attention to the SynScan version displayed when you power on the mount, if it's lower than 3.35, seriously consider to upgrade
Keep coming back to this thread with what you've done and what results you got, there are plenty of people here that have got their HEQ5 Pro mounts humming (near) perfectly, and we're all eager to help.
Cheers
Steffen.
