[QUOTE="Robbo, post: 750847, member: 256551"] It would be off track yes, if it was not setup properly, but not necessarily. It would be more difficult to achieve is the point. When making the inititial alignment with a motorised dish using a satellite that is exactly at your due NORTH location, the polar mount can be set to centre and alignment carried out. Assuming that all other things are correct, the dish would then follow the arc. However, when aligning to a satellite that is NOT at your due north, the polar mount has to turned either east or west (depending which way the satellite is with respect to your due north sat), before commencing alignment. However turning the motor to that satellite can be innacurate. Getting it wrong on such a large dish would mean the whole arc just crossing at that point only. Correction to my previous post, I note that you are in the southern hemisphere, so it should be due north rather than due south. [/QUOTE]
