I got the home position all sorted. Did a check on polar alignment tonight using the drift method, no star movement in 10 mins, so I reckon I am pretty well polar aligned.
The PHD graph is still shocking. I disabled the guide output and the dec and ra graph chased themselves off the scale.
Beginning to think it is either my Gemini guider port, dodgy starshoot autoguider, or a cable issue. I have a toucam which I will connect tomorrow night via gpusb and see if that will work ok. Beginning to clutch at straws now.
