Just a short note on a little software program which makes polar drift aligment a piece of cake as long as you have a live camera connected to a telescope.
This little program is $20 US and realy makes light work of drift aligment.
Fire up your imager and start Startarg. This program overlays your imagers movie image. It comes with a full set of instructions and tips to help you make fine adjustments to your polar alignment.
It is available from. http://www.andysshotglass.com/StarTarg.html
Hope this helps someone who had as many problems as I did.
