Thanks Paul, I think I know what the issue is for guiding but I dont know how to fix it.

If i put the guider in the telescope without the imaging camera (or OAG) the stars are more pinpoint, probally due to the OAG prism picking stars from the edge of the field. Guiding this way the graph is flat or within one pixel. When I try to guide on the OAG stars phd struggles to find the centroid and then slews the scope around when the stars not really moving at all.

I might try to move the prism towards the center of the field to catch some better stars.
