A Question about Off Axis Guiding

Hi all!
I have an Atik One camera with the OAG kit. I have not used it yet as I have preferred to learn other things. I am now ready to give it a try!
It has a Prism that can be adjusted. I assume the idea is to set it so that the edge of the prism is just on the edge of the image? I have had a play with it and moved so when I take a flat frame with my light box, then stretch the heck out of the image there is just a hint of a dark line at the edge. Procedure was to set it low so it was very obvious and then keep taking images while edging it up.
I assume a thin line can be dealt with via flats or should I keep going until it is completely clear?
