Hi Mick, As you are in Sydney, you will set up your rig as normal, with
the leg below the counterweights pointing due South [NOT magnetic South].
Point the scope to 0 degrees Dec and find a suitable moderately bright
star as close to where the scope is pointing as possible. When you have
obtained a straight line on your camera's LCD screen by following the
DARV instructions, point your scope low on the horizon East or West and
follow the instructions to get a straight line with whatever star you have chosen. Make all adjustments with the alt and az adjusters, not the motor
controls. Takes a while the first time, but after you've got it down pat
you can get accurate P.A. in a few minutes. Use shorter exposures at
first to see if the P.A. is way out. As the P.A. improves use longer
exposures as when P.A. is very close deviation will take longer to show up.
