hey guys just a quick one if phd is making north adjustments is it because I'm to far south i get a rms of 0.03   

so I'm fairly close to pa but the stars move in each pic just a little bit and anything over 15 mins is egg shaped stars

If guiding is good but you have egg shaped stars with longer subs then you probably have differential flexure problem. If that's the case, solution is OAG.

try the trail version of CCD inspector will show your curvature and tilt amongst other things.

Simple as well which was great for me load a picture and press the button.  You can compare images that way also if you have altered your set up.
