Going to answer my own question here. I was imaging the Statue of Liberty Nebula NGC3576 2 days ago and had some guiding success with the below.
It wasn't perfect but was the best I've had.. One thing to note. I've struggles to get a clear image out of the Edge, thought it might be Collimation, the OAG Prism being too low & obstructing, not perfect PA, checked all these things that could make the image look out of focus but in the end if your tracking isn't around the 1.5" or less error range then your images really suffer. Get this done before you start changing major setups.
Guide Camera Gain 320
Guide Focal Length 1458mm (should match main focal length after plate solve).
Calibration Steps 500
Max RA 600
Max Dec 600
RA Aggression =60%
Dec Aggression =60%
Exposure 2 Sec
I was imaging 60 sec subs as the above would stay stable the majority of the time but a slight blip from RA or Dec would rubbish the sub.. There wasn't a breath of wind but it just jumped randomly which annoyed me enough to drop the exposure down.
Hope it helps someone.
